MAKITA B-29723 Bi-Metal Hole Saw for Sheet Metal 22x20 mm

MAKITA B-29723 Bi-Metal Hole Saw for Sheet Metal 22x20 mm

The MAKITA B-29723 Bi-Metal hole saw is a high-quality annular cutter with a diameter of 22 mm. It is made of Bi-Metal material, combining a flexible spring steel body with High-Speed Steel (HSS) teeth enhanced with 8% cobalt. This 8% cobalt addition increases hardness and heat resistance, allowing the cutter to slice through hard metals (such as steel) and stainless steel efficiently. The hole saw has a working length of 20 mm, specially designed for drilling thin materials such as 0.8-5 mm sheet metal. This model must be used with an arbor and a pilot drill, which are sold separately.

Specifications
- Longer life: 8% cobalt-alloyed teeth offer superior strength and wear resistance when drilling metals and stainless steel.
- High cutting efficiency: Vari-Pitch tooth arrangement (4/6 TPI) reduces vibration during drilling, enabling fast and smooth cutting.
- Flexibility: The Bi-Metal body is highly flexible, reducing the risk of breakage.
- Chip ejection: Designed for efficient chip and heat dissipation (including optional features such as an ejection spring on select arbor sets).
Applications & Usage
- Metals: sheet metal, structural steel, aluminum, copper, brass
- Stainless Steel: Suitable for drilling stainless steel sheets up to 2 mm thick.
- Other materials: Plastic (PVC), wood, and plywood
