Put the guide pads back on the tool. and the insert cutting edge. If a pre setter is not available, use a micrometer or caliper. For a precise drill diameter measurement, it is recommended to test drill a hole and measure the hole diameter. STEP 5 Measure the drill diameter again to confirm that the required diameter is obtained on the DTD. STEP 2 Select the shim combinations according to the chart above to obtain the required hole diameter. Take into consideration that the actual diameter of the drilled hole tends to be slightly larger (usually +20 μm to +30 μm) than the drill’s nominal diameter — i.e. add 20 μm-30 μm to the measured drill diameter in Step 1 before the final drill diameter. STEP 6 Drill a hole to confirm that the required hole diameter is achieved. STEP 3 Remove the guide pads. 262 ISCAR
