Angular Metal Core Drilling Machine – ALFRA Rotabest® V32

B

Made in Germany by ALFRA

■ Horizontal metal core drilling machine for the tightest conditions. Perfect for use where regular metal core drilling machines cannot go due to their height. ■ Application areas: Steel construction (in between girder flanges), vehicle construction (truck frames), bridge construction, tower construction, tunnel construction, tersely everywhere, where it´s narrow ...

Suitable for the tightest spaces, wherever it is tight.

■ The total height is just 227 mm and can even be reduced to 185 mm by removing the handle. ■ The spur gear unit is designed for robust use and is fed using a ratchet leveler. Reversible for right- and left-handed operation. ■ Another advantage: the design of the angled gear unit ensures permanent lubrication and prevents dry running.

Fed using ratchet leveler, reversible for right- and left-handed operation

■ Used with the proven motors and magnet foot components from the Rotabest® series.

The application area of TCT Hole Saws differs from HSS-Bi-Metal Hole Saws. With ALFRA TCT Hole Saws, suitable to economically process stainless steel up to 2 mm (1/16”), unalloyed steels up to 4 mm (3/16”), plastics, PVC, aluminium, zinc, gypsum plaster boards and lightweight building boards, as well as asbestos. Do not use automatic feed, when working with pillar drilling machines. For the use on portable- and pillar drilling machines.Do not use automatic feed, when working with pillar drilling machines. Features: ■ High concentric running exactness through solid construction. ■ CAD-optimized cutting angles with specially ground section ensures high cutting capacity and long tool life. ■ Quick removal of drilled core through ejector spring for all hole saws up to 150 mm (5 29/32”) Ø. ■ Carbide tipping enables repeated re-grinding. ■ ALFRA hole saws are repairable. In the event of a tooth breaking, it can easily be replaced and resharpened. ■ Exchangeable center pin. ■ Use of MT tool holders from Ø 31 mm (1 7/32”). ■ For use on hand drilling machines (recommended up to max. Ø 40 mm; 1 9/16”) or stationary machines. Tips: ■ At thicker materials: cut 2-3 mm per cutting process, remove chips afterwards. ■ When cutting metals, a high- grade cutting oil should be used. Exception: Do not use cutting oil when using cast iron, use parrafin instead of oil when cutting aluminium. ■ Keep in mind: Always wear safety goggles. Another special technical feature: From Ø 15.2 mm (3/16”) to 30.0 mm (1 1/8”), the hole saw is made of one piece. From Ø 31.0 mm (1 3/16”) we use specially hardened tool holders to compensate for the torsional power in case of heavy operation, which avoids early shearing off of the tool holder shank. In terms of construction not comparable with any other make.

16 mm (5/8”) 10 mm (3/8”)

Ejector Spring Tapered center drill with pre- and post-cutter Centering without running off (center punching not necessary) Cutting geometries Variable teeth, less Vibration, longer tool life, smoother cutting.

This TCT Hole Saw is a multi-range Hole Saw for the universal use up to a material thickness of max. 10 mm (3/8”) (without ejector spring). Through its solid construction and an enhanced cutting geometry (Registered Utility Model No. 202 03 232 9), an improved cutting behaviour combined with a high cutting capacity and tool life, is achieved.

MBS – for almost limitless use

For the use on flat steel, as well as on pipes and vaulted materials. Cutting of overlapping holes is possible. For use on stationary and hand drilling machines (recommended up to max. Ø 40 mm; 1 9/16”). ■ Portable drilling Machines: up to 4 mm (1/8”) material thickness ■ Stationary drilling Machines: up to 10 mm (3/8”) material thickness (for material thickness over 6 mm (15/64”), it is necessary to settle and empty the chips several times). In case of heavy operation, we recommend Morse Taper Tool Holders, which are suitable from Ø 37 mm (1 7/166”).

Advantage: All MBS-Light type TCT Hole Saws are equipped with an ejector spring. The cut material is self-ejecting. The cut material is self-ejecting. Another special technical feature: From Ø 37 mm (1 7/16”), specially hardened tool holders are used to compensate for the torsional power in case of heavy operation which avoids early shearing off of the tool holder shank. In terms of construction not comparable with any other make.

ALFRA TCT-Hole Saws – MBS-Pro The TCT Multi-Range Hole Saw • Made in Germany by ALFRA Ø 18.0 - 100.0 mm = 13.0 mm shank Ø 11/16” - 3 15/16” = 33/64 ” shank Recommendation: Use exchangeable Morse Taper arbor MT2, MT3 or 13 mm straight shank from Ø 31 mm (1 7/32”) for stability reasons.

Clamping screw Basic body

30 mm (1 3/16“) 20 mm (25/32“)

Ejector Spring Tapered center drill with pre- and post-cutter Centering without running off (center punching not necessary) Cutting geometries Variable teeth, less Vibration, longer tool life, smoother cutting.

MBS-Multirange Hole Saws for universal use. Max. cutting depth 20 mm (25/32”) Suitable for flat materials but also for pipes and curved surfaces. Cutting of overlapping holes is possible. CAD optimized precision tools with high cutting performance and durability. For use on stationary and portable drilling machines (recommended up to max. Ø 40 mm; 1 9/16”) ■ Portable drilling Machines: up to 6 mm (15/64”) material thickness ■ Stationary drilling Machines: up to 20 mm (25/32”) material thickness at cutting depths from 6 mm (15/64”) we recommend clearing the chips. MBS hole saws can be resharpened, and it is possible to replace broken out teeth depending on the condition of the hole saw. Advantages: All Alfra TCT Hole Saws MBS-Pro type are equipped with an ejector spring. The cut material is self-ejecting. The cut material is self-ejecting.

Another special technical feature: From Ø 31 mm (1 7/32”), we use specially hardened tool holders to compensate for the torsional power in case of heavy operation, which avoids early shearing off of the tool holder shank. In terms of construction not comparable with any other make.

Multi-Step Drills – HSS DM O5

More precise hole diameter through cylindrical steps. Hole deburring through the next step. Application area: The ideal tool for sheet metal forming, for the electrical industry, HVAC or the common engineering or the switchboard industry. Suitable for all materials such as nonferrous metals, stainless steel sheets, thermoplastic and thermosetting plastics, as well as for steel sheets up to a max. material thickness of 6 mm. With the Multi-Step Drills, sheet metals can be centered, drilled and subsequently deburred in one work step. ■ A break of the drill tip mostly occurs through high feed forces at the start of the drilling operation. Multi-step drills with fixed drill tips are worthless then. A broken center drill in an ALFRA multi-step drill can be easily replaced. This more than compensates for the higher price. ■ Each stage is equipped with a radially adjusted relief grinding corresponding to its diameter. ■ Each stage is provided with an axial relief grinding and a relief angle on its cutting edge. ■ All step diameters are laser marked on the tool. Benefits of multi-step drills with keyway and 3 cutting edges: ■ The keyway allows the drill to make a chipping cut during drilling for better chip removal. ■ The special keyway geometry, arranged around the drill, makes for a longer cutting edge compared to the usual straight groove and noticeably easier cutting. ■ Spiral cut chip spaces guarantee an absolute running smoothness and a high cutting capacity. Tip: The tool life can be considerably prolonged by using of ALFRA Cutting Spray or ALFRA Coolant Stick.

Burr removal, Countersinking 4 or 6 mm Boring ■ Exchangeable center drills 6 4 chipspaces

Advantages of TiAlN hard coating: ■ Suitable for use on very hard materials (VA). ■ Offers optimal tool life with the same use at the highest cutting speeds. ■ Very high microhardness HV 0.05 of 3200 – so that the blue-black hard coating is more than 20% harder than conventional gold-yellow TIN coating. ■ Maximum working temperature: 800°C.

Standard values for the use of ALFRA Multi-step drills This drill was developed to bore perfectly round and deburred holes in sheet metal from 4 - 6 mm thick. The transition forms a radius which serves to deburr or bevel the hole at the same time. While conical one-lip bits drill a slightly tapered hole, our ALFRA multi-step drill achieves a cylindrical hole. The tools have axial-radial relief grindings and can be lightly reground on the breast of the cutting tooth. We recommend the use of pillar drilling machines, however, the small ALFRA Multi-step drills can be used on adjustable hand drilling machines. Sufficient cooling using ALFRA coolant stick or a bore emulsion is imperative. Speed chart rpm Type AM AM-1 PVD+PVK+DKI PVD-VA + SVB

The Core Drilling Principle

■ Core Drills machine only a fraction of the material at the same bore diameter than a twist drill ■ The remaining core is ejected after finishing the drilling process.

Economies on chipping volume of a core drill compared with a twist drill

■ Thereby minor power and feed pressures are required.

85% saving

■ When using twist drills, it is possibly required to pre-drill. This is entirely omitted when using core drills, you can directly drill with the requested diameter.

81% saving

The primary drilling time is abbreviated considerably depending on the cutting diameter.

Tips for tapping 1. Clearance Hole For Clearance Holes we recommend alongside mentioned taps, which safely conveys the chips out of the hole. The specially shaped grinding guarantees a safe re-mounting, when the tap opted out of the thread hole and returns in left hand rotation. 2. Tapped Blind Holes For Tapped Blind Holes we recommend alongside mentioned taps. The chips are conveyed out of the hole contrary to the cutting direction. Important: do not run aground with tap, as otherwise the automatic return run won‘t be activated. A correspondingly larger pre-drilling depth must be carried out.

Punching Unit APS 60/70/120 â&#x20AC;&#x201C; Notes on use How to select the correct ratio of material thickness to tool size

The choice of the proper tool size at a given material thickness is a usual question in daily practice.

Minimum tool size at a given material thickness

For customary punch models, an old rule says that the minimum tool size is the material thickness.

At a given material thickness, fig. 2 can be used for the rapid determination of the tool size. The values for Al, Cu, DIN S233 and St 70 are indicated.

This rule is no more valid for our hydraulically actuated punches. Example: The rule only still applies for fast moving mechanical presses: Thicker materials could cause the punch to break. With our ALFRA PRESS APS-punches, the process is carried out by a smooth, slow motion allowing the punching of holes with a diameter smaller than the material thickness.

You want to punch holes into a steel plate of DIN S233; the material thickness is 20 mm. Which is the minimum hole diameter to be punched? Look for the corresponding value on the solid line. Result: Minimum hole diameter is 15 mm.

But still, a certain minimum diameter has to be respected. For that reason, we have carried out tests, and the results are demonstrated in fig.1. Example: You want to punch holes into a steel plate made from DIN S233. Which is the correct ratio of material thickness to tool size? The shear strength of the material is at 30 kg/mm2 approx. The recommended ratio is represented by line A. The corresponding value on the ordinate is 1.3.

The dashed line represents the upper tolerance values, which can be used only for exception (reduced tool life). We recommend you to select the hole size by means of the solid line. ALFRA punches and dies are made of high-quality materials. But still, sometimes a tool may break. The following reasons have to be taken into account:

Result: The recommended ratio is 1.3.

1. Incorrect selection of the ratio of tool size to material thickness.

The upper tolerance limit for that ratio is represented by line B which at this point gives an ordinate value of 1.7. Hence, it is possible to punch holes with a diameter of only 1/1.7 of the material thickness. You may use this tolerance value for exception, but the service life of the tool will be significantly reduced.

2. The material is not aligned straight on the die.

We would like to remind you only to use line A for the correct determination of the ratio of material thickness to hole size.

3. Disturbing movements during the punch process. 4. The hold-down is damaged, or its height is not adjusted correctly, so that the material will be tilted during the removing of the punch. 5. The distance between hold-down and tool is too large. Thin sheets can be bended during the removing of the punch. In such cases, the tool breaks at the cutting edge in the form of thin leaves. In that case we recommend the hold-down to be equipped with a bridge or the utilization of a special hold-down.

ALFRA – Tips for right deburring

B

Model KFH 150, KFH 250, KFT 250, KFT 500

Rotating direction

Our precision high performance motors are continuously adjustable. We recommend to start with a low engine speed and to raise it continuously when milling.

When machining the work pieces on the table based models, the rotating direction must be obeyed.

The optimal engine speed can be detected by the running noise of the milling cutter and by the infeed.

When using the hand operated models (KFH 150, KFH 250) the running direction (compare arrow) must be considered. Synchronous milling is only applicable for a very small bevel height.

The tool depending cutting speed, can be found out with the help of a well known formula and therefore the revolution can be adjusted in advance: vc 1000 n = ––––––––––– U/min d x 3.14

Surface finish

d = cutter-Ø, n = rpm, 3.14 = Pi

Responsible for the milling cutter speed (N) and the cutting speed (Vc) are first of all the used material, the bevel height and the cutting geometry of the solid carbide-milling cutter.

The bevel height (h) For choosing the right solid carbide-milling cutter the bevel height is determining. When using the table based models KFT 250 and KFT 500 it must be considered, that the tool needs to be hold and controlled manually. If the milling power is too high, especially for little work pieces, the bevel height should be reached by several production steps. Don‘t do bigger bevels in one go!

Bevel width (b) The bevel width can be measured by use of the formula (b = h x 1.414)

The surface finish of the bevel is depending on the used solid carbide milling cutter and the material as well as on the chosen infeed. If the chips start to glow, the infeed was too high or the milling cutters too thin.

Tool saving costs In combination with the above mentioned models also standard solid carbide-end mill with face grinding can be used. By moving the milling cutter inside the arbor, the milling cutter can be consumed totally.

Cost reduction: The bigger part of the End Mill´s cutting range can be used by moving the End Mill in the collet.

TCT cutting tools – Technical terms

Clearance Angle Is the angle between the TCT tooth and the material to be cut. ALFRA TCT Cutters are equipped with serveral clearance angles at a cutting edge. Cutting Depth Is the maximum material thickness which might be cut with the particular tool (not to be mistaken with the constructive height of the tool). Chip Flute Takes the generated chips and advances this out of the bore. Chip Forwarding Pitch Forwards the chips from the TCT tooth to the chip flute. Chip Surface On this surface the chip is formed. Chip Angle Is the angle between tool axis and chip surface. Tooth Excess Length Is the carbide excess to the basic body. Tooth Height Difference Acts as a chip breaker.

HSS Bi Metal Hole Saws – Notes on use

B

To achieve the best results: 1. Use the hole saws at the recommended cutting speed, see guide table on the packaging. 2. Do not apply excess pressure. Apply a little more pressure for a harder material and less pressure for a softer material. 3. In order to achieve good centring, the centre drill must project approximately 6 mm beyond the teeth. It is recommended that the hole is first predrilled with a twist drill and then the centre drill is used in the adapter as a centring pin. 4. Use a good cutting oil when drilling metal. This extends the hole saw‘s service life and prevents premature blunting of the tooth tips. 5. The arbor of the adapter must be firmly clamped with the flattened sides correctly seated in the chuck. 6. The hole saw must cut into the workpiece at a right angle. Avoid tilting. Risk of accident. 7. If large hole saw diameters are used in hand-held drills, the hand-held drill must be held particularly firmly. A drill stand should be used where possible. 8. The adapter must be firmly screwed into the hole saw with all its thread and the driver pins must be firmly seated in the driver holes. 9. Secure the driver pins with the rotating ring or lock in the case of a quick-change adapter. 10. Wear protective goggles when working with the bi-metal hole saws and keep hands away in case saw runs out. Never attempt to stop with your hands a saw that is running off. 11. Lift the saw clear frequently, especially when cutting timber, chipboard and wood substitutes and remove the sawdust and chips. If this is not done, the tooth tips can burn and the hole saw will jam in the cut. 12. We recommend the following procedure when drilling timber, chipboard and wood substitutes: Drill a number of holes immediately inside the cut. This helps carry the chips away and avoids frequent interruptions in cutting to clean the tooth tips.

Enlarging existing holes Existing holes 32 mm (1 1/4”) or more in diameter may be enlarged with a simple trick: Take a 32 mm diameter hole saw and screw this inside the hole saw on the projecting thread of the A2 adapter. The inner hole saw then acts as a kind of guiding hole saw for extending existing holes, see photo.

What you absolutely must avoid: 1. Drilling at too fast or too slow a cutting speed. The teeth will glide over the material and become prematurely blunt. 2. Avoid bringing the saw teeth abruptly down on the workpiece, the teeth will break off. 3. Never cut metallic materials dry. Always use a cutting oil. 4. Never bring the saw up to the workpiece on a slant. There is a risk of injury when hand drills are used. The saw can break up or the arbor could be damaged. 5. Ensure that the hole saw is running true. Check the chuck as necessary.

If the workpiece is especially thick ... ... it is also recommended that you cut from both sides, or drill a number of holes immediately inside the circular cut. This helps carry the chips away and avoids frequent interruptions in cutting to clean the tooth tips.

6. Never screw the adapter‘s guide pins only partially into the hole saw guide holes. The thread of the hole saw could be torn out. 7. Never regrind the hole saw freely by hand. Have hole saws reground by a specialist. Care must be taken to ensure sufficient residual setting and a uniform tooth height. 8. If the tool arbor is pushed into the chuck or if the arbor shears off, the advance pressure is too great. 9. If the hole saw is unevenly worn on the outside, then the saw is not running true or the material to be sawn was not correctly clamped. 10. If the tooth tips are blued, the saw has been used without cutting oil, or at too high a cutting speed.

* Drilling in tiles only up to a scratch hardness of 6, mark centre, set the centre drill and drill through the glaze with at a low speed, allow the saw teeth to penetrate the glazing uniformly, running as smoothly and level as possible, so that the edge of the hole is made without chipping. Continue drilling at a normal drilling speed. Tiles with a scratch hardness greater than 6 may only be cut with diamond or carbide hole saws.

Notes on use • Use rotation only. Switch off impact or hammer drill. • Impact and shock on the sharp, ground carbide cutters can lead to small carbide splinters and thus to a severe loss of performance. • Do not tilt the hole saw in the hole. • Remove the drill core after each operation. Remove the sawdust when drilling timber and timber products. Notes on use For multipurpose hole saw with rim countersink • The rim countersink is placed between hole saw and adapter and the carbide cutter is used to make a countersink in timber and timber substitutes. This makes it possible to fit sockets flush. Important notes on use - The hole saw with rim countersink may not be stopped before it is removed. - Advance with care, to prevent the cut edges tearing.

Speed Chart – Multi-Step Drills/Conical One-Lip Bits

ALFRA-Multi-step drills

ALFRA HSS DM 05 precision Multistep Drill

These drills were especially to drill perfectly round and simultaneously deburred holes insheet metals of 4 - 6 mm. The radius transition simultaneously deburrs or bezels the holes. While conical one-lip bits drill slightly conical holes, cylindrical holes can be drilled with ALFRA Multistep drills. The tools are axial-radially relief ground and ccan be resharpened at the breast of the cutting tooth.

• Take notice of the cuttig speed • Grease the cutting lips in case of application

We recommend the use of pillar drilling machines, however, the small ALFRA Multi-step drills can be used on adjustable hand drilling machines. Imperatively use sufficient cooling (ALFRA coolant stick or bore emulsion)?
