With CrazyDrill Pilot SST-Inox, Mikron Tool introduces a pilot and short drill for stainless steels, heat-resistant and CrCo alloys in the diameter range of 0.2 mm to 2.0 mm (.008” to .079”, fractional inches available). This pilot drill is coated, has a cutting edge for 90° chamfer, integrated through-tool coolant channels in the shaft and a digressive helical flute. As pilot drill it is the ideal complement of the twist drill types CrazyDrill SST-Inox and CrazyDrill Flex SST-Inox and it is suitable as well for short drilling up to a drilling depth of 3 x d.
CrazyDrill Pilot SST-Inox is the perfect preparation for deep hole drilling with CrazyDrill Flex SST-Inox or CrazyDrill SST-Inox. Drilling quality (position and alignment accuracy, no measurable transition from pilot to follow-up hole) and stable machining process are assured due to matched diameters of the tools.
An additional cutting edge for 90° chamfer (countersink drill bit) allows, simultaneously with the pilot bore, the placement of a 90° countersink, hence an additional chamfer tool becomes redundant. Furthermore this tool can also be used as a short drill for drilling depths of up to 3 x d.
