Both variants of this drill bit for stainless steel meet the challenges of machining 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. 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.
