About this product
This 21mm bi-metal holesaw from Bahco's Sandflex range is suited to standard electrical installations, conduit work, junction boxes and general mounting tasks in residential and light commercial settings. It uses a variable pitch blade (4-6 TPI) to reduce vibration and give smoother, more controlled cutting. The cutting edges are made from high-speed steel for hardness and long-lasting sharpness, while welded seam construction helps maintain accuracy. The heat-treated body adds strength, allowing the saw to cut sawable materials up to 38mm thick. It is compatible with portable electric or pneumatic tools, as well as a range of drilling and machine tools. Arbors to suit are available separately.
