MAKITA B-36033 Bi-Metal Hole Saw for Sheet Metal 73x20 mm

MAKITA B-36033 BIM Hole Saw for Sheet Metal Size 73x20 mm

The MAKITA B-36033 BIM hole saw is a professional-grade annular cutter designed for drilling holes with a 73 mm diameter, falling into the large size category. It features a durable Bi-Metal construction with teeth made of high-speed steel (HSS) infused with 8% cobalt (8% Cobalt Alloy), providing superior strength and high resistance to heat and wear when cutting through hard metals. This hole saw is designed for cutting sheet materials, particularly sheet metal, with a working depth of 20 mm (according to sheet metal model specifications) or potentially up to 38 mm (according to general Bi-Metal hole saw specifications for this size). This hole saw must be used with a Makita arbor and pilot drill bit, which are optional accessories sold separately.

Specifications
- High durability in metal applications: Teeth infused with 8% cobalt deliver strength and a long service life, especially when drilling metal and stainless steel.
- Excellent cutting performance: Vari-Pitch tooth design helps reduce vibration during drilling, making cuts faster and smoother.
- Flexibility and safety: The Bi-Metal construction provides the hole saw body with high flexibility, reducing the risk of breakage if jamming occurs.
- Chip ejection: Features slots for efficient material chip and heat dissipation.

Applications & Usage
- Pipe and electrical conduit installation: Drilling large holes for electrical conduits, ventilation pipes, or 73 mm water pipes.
- Control panel assembly: Drill large metal panels for installing gauges or large control devices.
- Construction/building work: Drilling holes for installing spotlights or other fixtures.
