Brazed Single-Crystal Cutting Tools
Finished SCD tools on a carbide shank, for ultra-precision and mirror-finish machining.
The cutting edge is synthetic single-crystal diamond, one continuous crystal free of grain boundaries and pores, brazed onto a carbide shank.
Single-crystal diamond tools are the primary tool in ultra-precision machining, reaching very high workpiece accuracy and very low surface roughness, down to a mirror finish.
- Ultra-high hardness and wear resistance
- Uniform wear resistance and long service life
- Extremely low coefficient of friction and cutting resistance
- Excellent chemical stability and anti-adhesion properties
- Rigid cemented carbide shank
