About this product

This 155mm Bi-Metal M42 HSS Hole Saw is engineered for demanding drilling tasks. Made from premium M42 high-speed steel, it combines exceptional hardness with heat and wear resistance, maintaining sharpness even during extended high-speed operation. The bi-metal construction flexes without cracking, reducing deformation under load.

Sharp Performance, Long Life

The cutting teeth (≥65 HRC) stay keen through tough materials. The flexible body absorbs stress, extending blade life and delivering cleaner cuts in PVC, gypsum board, wood, plastic, rubber, and thin metals.

• Spring-eject system automatically pushes out cut disc after drilling.

• Multi-hole pattern improves chip evacuation, preventing clogging in thick materials.
