Product attributes
Designed for stainless steel
For straight or spiral flutes, for short chipping materials.
Lead of screw thread
ISO Metric coarse thread
Steamtempered (Black finish)
more +
Steamtempered (Black finish) is a process where a layer of iron oxide is formed on the surface of the tool. This layer increases the abrasion resistance of the blade, increases corrosion resistance and improves lubrication of the tool. The most effective use is for drill bits and taps.
Angle of thread
Thread standard
Very high performance high speed steel with good toughness for milling cutters and for milling of materials up to the strength of 1200 MPa.
