Total length(incl. shank): 100mm

Max. thickness of drilled material: 4mm
Material: HSS-XE - high-alloy cobalt high-speed HSSE steel(68 HRC)
Coating: TiN-GOLD(basic coating), increases the life of the drill when drilling with very limited cooling(spray , paste), also for dry cutting

Cutting conditions - steel: 1100 to 260 rpm
Cutting conditions - stainless steel: 550 to 120 rpm
Smaller diameters can be drilled at at higher speeds, with increasing drilling diameter, the cutting speed and speed need to be reduced. Failure to maintain the speed or overheating the drill may cause it to become dull.

Transitions to a larger diameter also perfectly needle the drilled hole.

Thanks to the spiral groove, the drilling is smooth, the chips do not stick, low cutting forces, the drilled material has fewer burrs and the tool has a longer endurance.
