MAKITA B-29789 Bi-Metal Hole Saw for Sheet Metal 33x20 mm

MAKITA B-29789 BIM Hole Saw for Sheet Metal, Size 33x20 mm

The MAKITA B-29789 BIM Hole Saw is a high-quality annular hole saw made of Bi-Metal material—combining spring steel for the body and flexibility with high-speed steel (HSS) infused with cobalt (approx. 8% Cobalt) for the teeth. This delivers high strength, durability, and flexibility, helping reduce the risk of breakage during heavy use. The hole saw has a diameter of 33 mm and a working length of 20 mm (some sources list a cutting depth of 38 mm or 39 mm for general Bi-Metal hole saws in this series, but the 33x20 mm model has a working depth of 20 mm). Ideal for use with Makita arbors and HSS pilot drill bits.
