MAKITA B-29701 Bi-Metal Hole Saw for Sheet Metal 20x20 mm

MAKITA B-29701 BIM Hole Saw for Sheet Metal, Size 20x20 mm

The MAKITA B-29701 BIM Hole Saw is a professional-grade annular cutter with a 20 mm diameter. The body is made from Bi-Metal material, combining a flexible spring steel body with ultra-tough teeth made of High-Speed Steel (HSS) alloyed with 8% cobalt (8% Cobalt Alloy). The cobalt addition ensures high hardness and heat resistance when cutting hard metals. The hole saw has a working length of 20 mm, specifically designed for drilling thin sheet materials such as 0.8-5 mm sheet metal. This hole saw must be used with a Makita Arbor and Pilot Drill, which are accessories sold separately.
