Small drill for aluminum
for highest degree of performance
and cost-effectiveness

Optimal chip removal, extraordinary tool life, high productivity and simultaneously excellent surface quality – all of these requirements are met by CrazyDrill Alu from Mikron Tool. The tungsten carbide drill for aluminum guarantees that its user enjoys maximum profitability. Due to its three-flute geometry it is self-centering.

CrazyDrill Alu is available from stock in the diameter range of 0.4 mm to 3 mm (.016” to .118”) and in the usable lengths of 5 x d and 10 x d.

CrazyDrill Alu 
for deep holes in aluminum

This CrazyDrill drill for cast and wrought aluminum alloys produces extraordinary machining results. Most notably it impresses with its extraordinarily high drilling speed and tool life. This type of drill bit is not only impressive in pure aluminum because of the especially adapted coating, it also exhibits a considerably longer tool life compared to other available tools in the market when machining silicon-based aluminum alloys. 

This drill for aluminum is self-centering due to its three flutes. This means centering or pilot drilling, which is needed in long twist drill types, is no longer required.

A straight hole (no deviation), the best roundness and high hole surface quality are ensured. Pilot drilling or centering is only recommended on an irregular or inclined material surface and, if needed, for higher position accuracy. These are carried out ideally with CrazyDrill Pilot or with CrazyDrill Crosspilot when drilling on inclined, convex or concave surfaces. Both pilot drills are perfectly adapted to CrazyDrill Alu in terms of diameter and tolerance (no measurable transition and no jamming). 

Its helical groove geometry provides for optimal chip flow and only minimum chip removal is needed (for drilling depths > 5 x d). With its external cooling CrazyDrill Alu is the optimal solution for all aluminum alloys up to a drilling depth of 10 x d. For deeper holes Mikron Tool recommends drills with through-tool cooling such as CrazyDrill Cool and CrazyDrill Cool XL.

Due to its remarkable properties the drill for aluminum CrazyDrill Alu significantly increases the reliability and productivity for its user.

In addition, drill regrinding and recoating of this tool (from diameter 1.4 mm and higher) improves cost-effectiveness considerably.

CrazyDrill Alu is available from stock drill bit sizes of 0.4 mm to 3 mm (.016” to .118”) in increments of 0.05 mm (.002”). Its standard drilling lengths are 5 x d and 10 x d.
