Set of bimetal hole saws with teeth made of HSS M42 cobalt high-speed steel, body made of spring steel alloy
Bimetal construction ensures high resistance of the carrier part to cracking, and M42 high-speed steel teeth provide much higher hardness and wear resistance compared to standard HSS steel.

Adapted for mounting an adapter for hex or SDS-plus shank.
Requires use of adapter and pilot drill.
Drilling in steel should be done wet.
Alternating tooth count 4/6 TPI allows drilling in materials of varying hardness.
Side surfaces of the hole saw have holes for easier removal of the core after drilling.
