MAKITA B-29860 Bi-Metal Hole Saw for Sheet Metal 54x20 mm
The MAKITA B-29860 Bi-Metal Hole Saw is a premium-range annular cutter for drilling 54 mm diameter holes. Constructed with durable Bi-Metal, the teeth are made of high-speed steel (HSS) with an 8% Cobalt Alloy, a crucial component that makes the saw highly resistant to heat and wear when drilling hard metals such as steel and stainless steel.This hole saw has a working length of 20 mm, specifically designed for cutting thin materials (sheet metal), offering a cutting capacity of 0.8–5 mm in mild steel and 0.8–2 mm in stainless steel. For convenient operation, this hole saw must be used with a compatible Makita arbor and pilot drill, sold separately.

Specifications
- Maximum Durability: 8% cobalt-alloyed teeth provide superior strength and a longer lifespan when drilling hard metals and stainless steel.
