MAKITA B-31740 Ezychange Quick-Release Bi-Metal Hole Saw 52x40mm

MAKITA B-31740 Ezychange BiM HS Quick-Release Hole Saw Size 52x40mm

Specifications

- The MAKITA B-31740 hole saw is a Bi-Metal (BiM) hole saw for 52 mm (approx. 2-1/16 inch) hole drilling with a maximum usable cutting depth of 40 mm.

The body is made of Bi-Metal High-Speed Steel (HSS Bi-Metal) with teeth reinforced with 8% Cobalt. Cobalt enhances strength and heat resistance against friction when drilling hard materials such as thick metal and stainless steel, ensuring a long hole saw service life and high performance.

Key feature                                                                                                                                                                                                                          is compatibility with the Ezychange Quick-Change System, Makita's unique quick-release mechanism.
