MAKITA B-11449 Quick-Release Hole Saw Ezychange BiM HS Size 65x40mm

Specifications

- MAKITA B-11449 Hole Saw is a Bi-Metal (BiM) hole saw bit for drilling large 65 mm holes with a maximum 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
