MAKITA B-29686 Bi-Metal Hole Saw for Sheet Metal 17x20 mm

MAKITA B-29686 BIM Sheet Metal Hole Saw 17x20 mm

The MAKITA B-29686 BIM hole saw is a professional-grade annular cutter designed for drilling 17 mm diameter holes. It features a Bi-Metal construction, combining a flexible body material with exceptionally tough cutting teeth. The teeth are made of high-speed steel (HSS) alloyed with 8% cobalt (8% Cobalt Alloy). This cobalt addition improves resistance to heat and wear, ensuring a long service life when drilling hard metals. The hole saw has a working depth of 20 mm, specifically engineered for cutting through thin sheet materials. This hole saw must be used with a Makita arbor and pilot drill bit, which are optional accessories sold separately.

Specifications
- High wear resistance: Teeth alloyed with 8% cobalt maintain tooth sharpness and extend tool life when drilling hard metals and stainless steel.
- Excellent cutting performance: Vari-Pitch (variable tooth spacing) design reduces vibration during drilling, resulting in fast, smooth, and accurate cuts.
- Flexibility and safety: Bi-Metal construction gives the hole saw body high flexibility, minimizing the risk of breakage.
- Specialized size: 17 mm size is ideal for specialized small to medium hole drilling tasks requiring high precision

Applications & Usage
- Electrical and electronic installations: Drilling holes for small conduits, sensors, or switches
- Control cabinet assembly: Drilling metal panels for installing various 17 mm components
- Sheet metal work: Maintenance work and sheet metal component assembly
