Overview
Mfr description
04139416 LETTER N 135 DEG; COBALT JOBBER
- Cobalt is harder than high speed steel and provides better wear resistance
- It is commonly used on high tensile alloys
- Oxide/gold finish provides a polished finish and prevents chip building, galling and welding on a workpiece
- It is commonly used on low carbon, stainless steel and ferrous metals
- Regular, also known as medium spiral bits, are used in general purpose applications
- They are used on soft, nonferrous materials
- Spiral flutes are constructed with a higher flute angle to remove chips more easily.
