PLUNGING CUTTERS
F1
ISCAR offers several plunger options which were designed for deep cavities and high shoulder milling. The tools are very effective and economical for deep machining of slots, straight and sloped walls which require very long tool overhang. The main feature of the plunger tools is that the loads on the machine, tool and workpiece are mainly axial, avoiding bending moments. It is recommended to use horizontal machines with an abundant coolant stream when machining deep cavities. Horizontal tool and cavity orientation allow gravity to enhance chip removal.
HTP
TANGPLUNGE HTP plungers carry tangentially clamped inserts on the frontal face of the tools, featuring high durability and excellent cutting performance. The tools are available with 3 insert size options: HTP LNHT 0604, HTP LNHT 1006 and HTP LNHT 1606. They all have coolant holes for efficient edge flushing and chip evacuation. The HTP LNHT … tangentially clamped right-hand inserts feature four cutting edges, with a positive rake face for reduced forces during machining and high chip removal. The insert orientation on the tool results in excellent machined surface flatness. The integral shank tools are available as endmills with integral shank FLEXFIT and SHANKMASTER, which have a threaded connection modular shank option in a diameter range of 16-40 mm. They are also available as shell mills in in a diameter range of 40-100 mm. The shell mill plungers can also be used for general side milling applications.

PH
Center cutting plunger that uses a very strong, double-ended insert with 4 cutting edges. The tools have a cylindrical or a CLICKFIT shank option. In case of vertical machining, the PH-A plunger (which has a spiral, drill-like flute) is recommended. This tool type evacuates chips effectively.
PLX
Side plunger equipped with standard XCMT 120408TR inserts, featuring a maximum width of cut - ae = 11 mm for plunging and a maximum depth of cut - ap = 9 mm for tangential milling. Each insert has two cutting edges. The tool is multifunctional for rough plunging operations and light milling or semi-finishing. With the PLX cutter – with an overhang of up to 3-3.5xD – there is no need for angular retractions. (This is normally done in order to avoid insert breakage and scratching the walls of the workpiece during retract pass). The PLX cutter enables faster retraction from the workpiece and significantly reduces machining time and failure. There is no need to apply any special CNC programming for the retract pass. Operations with very long overhangs are performed by the PLX cutters with only 45° angular retractions. No other cutters will function under such long overhang conditions. The PLX cutters have a 17° angle built into the insert, which reduces the radial cutting forces and prevents insert breakage. The cutters also have high tooth density, which means that the PLX cutters can run very fast. All PLX cutters are manufactured with coolant holes for better chip evacuation.

USER GUIDE
The PLH...- type (trepanning) plungers have a hollow center. This requires a specific pattern so the column that remains after each plunge is removed completely and smoothly. The coordinates in Table 1 produce the pattern shown in Sketch 7. This provides the optimal results for the PLH D75-27-13 type plunger (outer diameter of 75 mm, inner diameter of 24 mm).
