Adjusting of tool diameter in increments of 0.01mm by changing inserts and putting a shim underneath the guide pads. The tools do have an adjusting range within 0.25mm (..,00 - ..,24mm) (..,25 - ..,49mm) (..,50 - ..,74mm) (..,75 - ..,99mm). For the smallest diameter of each drilling range no guide pad shims are used.

Adjustment of tools Drill heads will be adjusted to the ordered drill diameter in-house. Stop plate thickness "S” is engraved into the drill head body (see below)
Tools can be adjusted in diameter by using guide pad shims and exchanging the stop plate. The maximum adjusting range is 0.25mm diameter.

The exact drill head diameter D1 is adjusted by exchanging the stop plate. The difference between D1 and D2 must be at least 0.02mm and at most 0.06mm. D1 should be always bigger as D2.

Example: The drill head 64-1121-000 with D1 = 45.00 should be adjusted to D1 = 45.22 mm Engraved in the head is a stop plate thickness S = 1.51 mm for a drill head diameter 45.00 mm. For adjusting the drill head to the new diameter guide pad shims # 10-0800-4919/0.1mm thickness and a stop plate # 01-2050-610-S1.63 are used.

Stop plate system When using identical tools with exactly the same drill head diameter, the thickness of the stop plate (dimension "S”) can vary due to manufacturing tolerances of the milled drill head body.
Thickness "S” is engraved in the stop plate as well. When re-ordering, please state order number as well as the dimension "S” of the requested stop plate.
