Material
Bi-metal M42 high speed steel cutting edge.
Bi-metal (BIM) is a high-carbon steel body for flexibility and break-resistance, and high-speed steel cutting edge for heat-resistance, hardness, and durability. With these holsaws been M42, they will have a even greater heat-resistance, wear-resistance, than their M3 counterparts.
