Quick and accurate
with deep-hole drill
CrazyDrill Cool XL 

The coated small drill CrazyDrill Cool XL from Mikron Tool (in the diameter range of 1 mm to 6 mm / .039” to .236”) is available in drilling lengths of 15, 20 and 30 x d for drilling diameters of 1 mm (.039”) and up and up to 40 x d for diameters of 2 mm (.078”) and up. Thanks to its newly developed geometry it meets the very challenging conditions of drilling a deep hole perfectly and is an ideal alternative to a gundrill. The outcome: an outstanding tungsten carbide drill for steel that produces short chips in all steel alloys. This is an essential requirement for smooth chip removal in drilling depths of up to 40 x d. The tool is designed so that holes up to the maximum depths can be produced in one step without chip removal, and this at the highest cutting speeds and feed rates. The through-coolant supply contributes to this and guarantees good cooling at the tip and hence outstanding tool life.

Extra long drill with through-tool cooling CrazyDrill Cool XL

Thanks to the special design of the CrazyDrill Cool XL, the deep-hole drill program from Mikron Tool in drill size diameters of 1 mm to 6 mm (.039” to .236”) and for depths of up to 40 x d, the best drill bit for steel (alloyed and not alloyed, stainless), cast iron, aluminum and titanium produces short chips in all drilling stages. Chips do not coil up and the chip shape determines successful deep-hole drilling process. The cutting speed and feed rate ratio has to be selected so that short chips are produced.

The two through-tool cooling channels, going all the way up to the drill tip, ensure constant cooling and simultaneously good chip removal. The tool generally reaches the full drilling depth in one single step (apart from titanium), and therefore chip removal is no longer required. An admirable performance.

Targeted cutting-edge treatment, before coating, and the final polishing of drill flutes and tips ensure excellent cutting conditions and tool life.

Thanks to these features CrazyDrill Cool XL reaches maximum drilling speeds and produces the highest alignment and diameter accuracy. Its simple, clearly defined operation and perfect geometry ensure reliable, economical and accurate deep-hole drilling (outstanding alternative to gun drilling), long tool life and best surface quality.

High-grade carbide of the latest generation and the most accurate grinding technology ensure that this product line meets the strictest quality requirements. Moreover, the drill with through-tool cooling can be reground and recoated and this increases the cost-effectiveness of this tool. The performance of a re-sharpened CrazyDrill Cool XL is equal to that of a new drill in terms of efficiency, precision and hole quality.
