MAKITA B-29670 Bi-Metal Hole Saw for Sheet Metal 16x20 mm

MAKITA B-29670 BIM Sheet Metal Hole Saw 16x20 mm

The MAKITA B-29670 BIM hole saw is a professional-grade annular cutter designed for drilling 16 mm diameter holes. It features a durable Bi-Metal construction, combining a flexible spring steel body with exceptionally tough cutting teeth. The teeth are made of high-speed steel (HSS) alloyed with 8% cobalt (8% Cobalt Alloy). This cobalt addition increases hardness and heat resistance, ensuring a long tool life when cutting through tough metals. The hole saw has a working depth of 20 mm and is specially engineered for drilling thin sheet materials, such as sheet metal up to 5 mm thick. This hole saw must be used in conjunction with a Makita arbor and pilot drill bit, which are accessories that must be purchased separately.

Specifications
- Exceptional durability: Teeth alloyed with 8% cobalt offer high strength and wear resistance, delivering a long lifespan when drilling hard metals and stainless steel.
- Cutting performance: The Vari-Pitch (variable tooth pitch) tooth arrangement reduces vibration, delivering fast, smooth, and precise cuts.
- Flexibility and safety: Bi-Metal construction gives the hole saw body high flexibility, minimizing the risk of breakage.
- Specialized size: The 16 mm size is ideal for jobs requiring precise small holes to accommodate small conduits or locknuts.

Applications & Usage
- Electrical and electronics installation: Cutting openings for conduit pipes, switches, or small sensors.
- Control panel assembly: Drilling sheet metal panels to mount 16 mm components.
- Maintenance work: General small-hole drilling in sheet metal applications.
