The Titanium Nitride (TiN) coating is an extremely hard ceramic. It is often used as a coating on HSS to improve hardness and durability
Features What makes these step drills special?
Because CBN (cubical boron nitride) is a much harder abrasive than even silicon carbide or corundum, a better and sharper cutting edge is achieved without burrs.
CBN-ground flutes without burrs mean a superior cutting edge and longer tool life
Each step has a radially adjusted relief produced by CBN grinding, relating directly to the diameter of the step, so the cutting edge is always the highest point of the diameter
Each step is axially CBN relief-ground, meaning the cutting edge is also the highest point of the axial cutting axis
The cutting edge of each step has relief angle, meaning the cutting edge is also the highest point in advance direction
The CBN-ground point ensures centering and spot-drilling, even in thin-walled material
Stainless steel and aluminum should be drilled at speeds no faster than 300 rpm. Cutting oil must be used to preserve the life of the cutting tool when exceeding diameters of 1/2" and up.
