MAKITA B-36077 BIM Hole Saw for Sheet Metal 86x20 mm
The MAKITA B-36077 BIM hole saw is a premium range annular hole saw designed for cutting 86 mm diameter holes. It features a robust Bi-Metal construction with high-speed steel (HSS) teeth enhanced with 8% cobalt alloy, a critical element that ensures high heat and wear resistance during drilling through hard metals such as steel and stainless steel.This hole saw has a working depth (Working Length) of 20 mm, specifically designed for cutting thin materials (Sheet Metal), with a cutting capacity of 0.8-5 mm thickness in general steel and 0.8-2 mm thickness in stainless steel. The Vari-Pitch tooth design ensures efficient cutting and reduced vibration. This large-sized hole saw requires an appropriate Makita arbor and pilot drill bit, which are sold separately.

Specifications
- Maximum Durability: 8% cobalt-alloyed teeth provide superior strength and a longer lifespan when drilling hard metals and stainless steel.
- Smooth cutting: Vari-Pitch tooth design (variable tooth pitch) reduces vibration and snagging, enabling fast drilling and clean holes.
- Flexibility and safety: Bi-Metal construction provides the body with high flexibility, reducing the risk of breakage.
- Large size for installation: 86 mm size is ideal for drilling large holes for pipes or control devices.

Applications & Usage
- Pipe and electrical installation: Drills openings for conduits, ventilation ducts, or 86 mm pipes.
- Control panel assembly: Drill large metal panels for installing gauges or large control devices.
- Construction work: Drill large holes on structures or drywall to install lighting fixtures.
