GARANT Master Steel Micro solid carbide stepped pilot drill, plain shank DIN 6535 HA 2.5×D, AlCrN, ⌀D1 m6: 3mm

High-performance micro pilot drill in two versions for universal material use, focussing on the machining of steel. Drilling and piloting can be performed in a wide range of applications, even on sloping or curved surfaces. Maximum process reliability due to exactly matching tools within the overall system. Optimum compromise between core diameter and flute size for optimum chip evacuation – even with long-chipping materials.

For process reliability when using micro-drills as from 8×D, a pilot hole of at least 2×D is required. Please always ensure that the pilot hole is free from chips before using the subsequent drilling tool. We recommend setting a 90° counterbore after the pilot hole has been completed. For critical applications, reduce the feed rate of the tool by 50% before entering and exiting the material. Please make sure that you use a suitable tool clamping device (shrink-fit chuck, hydraulic chuck) with a radial run-out of less than 0.003 mm.
Stepped pilot drill with 160° point angle and reinforced design for direct drilling/piloting on sloping and curved surfaces up to a maximum angle of 50° from the horizontal, as well as for drilling and 90° countersinking on straight surfaces in one step.
