With CrazyDrill SST-Inox Mikron Tool offers two exclusive drill types for drilling in stainless steel up to 12 x d and in the diameter range of 0.2 to 2 mm (.008” to .079”, fractional inches available): CrazyDrill SST-Inox type IN (8 x d / 12 x d) for drilling with external cooling and CrazyDrill SST-Inox type IK (8 x d / 12 x d) for drilling with integrated cooling.
Both variants of this best drill bits for stainless steel meet the challenge very well. A challenge which involves the machining of stainless steels, chromium-cobalt alloys, heat-resistant steels and even lead-free brass. They differ in their geometry significantly from other products available in the market today. For the first time in this drill size diameter range there is efficient cooling, an important factor for long tool life. Significant advances were also made in relation to cutting performance: a drilling process up to ten times quicker is possible.
As a perfect preparation for high-precision position accuracy, Mikron Tool recommends for CrazyDrill SST-Inox 12 x d the use of the pilot drill CrazyDrill Pilot SST-Inox with integrated cooling.
For drilling depths of up to 8 x d, CrazyDrill SST-Inox can be used on regular and straight surfaces without a centering or pilot hole. In case of irregular respectively rough surfaces we recommend the pilot drill CrazyDrill Pilot SST-Inox or the centering drill CrazyDrill Twicenter, both with internal cooling.
For both drilling types (8 x d / 12 x d) and on inclined surfaces, CrazyDrill Crosspilot is the perfect pilot drill.
