Mikron Tool’s CrazyDrill Cool Titanium ATC/PTC series is designed to provide maximum process reliability when drilling pure titanium and its alloys, enabling higher cutting performance results, longer tool life and excellent hole quality.

The new CrazyDrill Cool Titanium series is offered in the diameter range of .039" – 1/4" (1.0 - 6.35 mm). For pure titanium, Mikron Tool developed short drills with 3 × D and drills with 6 × D. For titanium alloys, Mikron Tool relies on drills with 6 × D and 10 × D in combination with a pilot drill.

The drills feature two cooling channels with large cross-sections to carry coolant to the drill tip and guarantee constant cooling including lubrication of the cutting edges. At the same time, the massive coolant jet flushes the chips through the polished flutes and prevents chip jams. The specialized shape of Mikron Tool’s cooling channels enables a 4X higher volume of coolant to be shot through the tool at the same pressure.

Mikron Tool has developed two specific geometries, one for pure titanium grades and one for titanium alloys. According to the company, controlled chip removal, high drilling speeds, long tool life, repeatable processes and optimum drilling quality for these titanium materials are guaranteed.

Mikron says its new high-performance drills for titanium have up to 3X longer tool life and work with twice the feed than its current competitors. Drilling with the ATC version is completed in one shot, without multiple machining steps.
