MAKITA B-29745 Bi-Metal Hole Saw for Sheet Metal 27x20 mm

MAKITA B-29745 BIM Hole Saw for Sheet Metal Size 27x20 mm

The MAKITA B-29745 BIM Hole Saw is a professional-grade cylindrical cutting tool used for drilling 27 mm diameter holes. The body is made of Bi-Metal material, providing flexibility to the barrel and rigidity at the teeth. The saw teeth are made from High-Speed Steel (HSS) with 8% Cobalt Alloy, which significantly increases resistance to heat and wear when cutting through hard metals. The hole saw has a working length of 20 mm, specifically designed for drilling thinner sheet materials such as sheet metal, aluminum, or stainless steel (appropriate thickness). This hole saw requires an Arbor and Pilot Drill from Makita, sold separately.

Specifications
- High Wear Resistance: With teeth reinforced with 8% cobalt, it maintains sharpness and provides a long service life even when drilling hard materials such as stainless steel.
- Excellent Cutting Performance: The Vari-Pitch tooth configuration (variable tooth pitch) significantly reduces vibration, resulting in faster and more precise drilling.
- Safety and Flexibility: The Bi-Metal construction gives the hole saw body flexibility, making it resistant to breakage in case of binding during operation.
- Chip Evacuation: Designed with slots for proper evacuation of chips and heat dissipation.

Applications & Usage
- Metals: Sheet metal, general steel, aluminum, copper.
- Stainless Steel: Suitable for drilling thin stainless steel sheets.
- Other Materials: Plastic (PVC), plywood, fiberglass sheets.
