MAKITA B-11455 Ezychange Quick-Release BiM HS Hole Saw Size 70x40mm

Specifications

- MAKITA B-11455 hole saw is a Bi-Metal (BiM) hole saw for drilling large 70 mm holes 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.

A key feature is its compatibility with the Ezychange Quick-Change System, Makita's unique quick-release mechanism. This system allows users to:

Quickly change between different hole saw sizes without the need for additional tools

Ability to easily push and release the cut core slug from the back of the bit, which is especially useful for large-diameter bits

Progressive Tooth Geometry design ensures smooth drilling start, reduces vibration, and increases cutting speed                                               Application
