BIMETAL HOLE SAW STEEL M42
- Bi-metal hole saw with teeth made of HSS M42 high-speed tool steel with 8% cobalt, body made of alloy spring steel
- The bimetallic structure ensures high resistance of the load-bearing part to cracking, and the M42 high-speed steel teeth ensure much higher hardness and wear resistance compared to ordinary HSS steel
- Designed for processing metals, in particular stainless steel, steel, aluminum as well as non-ferrous metals, plastics and wood
- Adjusted to mounting an adapter for hexagonal or SDS-plus socket
- Needs adapter and centering drill
- Steel drilling should be made when wet
- The alternating number of teeth 4/6TPI allows drilling in materials of different hardness
- The hole saw has holes on its side surfaces to facilitate easier removal of the disc remaining after drilling
- Drilling depth 38 mm
- Packed on a hanger
