Description
The Bi-metal hole saw is a 21mm diameter hole saw with HSS teeth that has a variable pitch to improve harmonic vibration and a better chip clearance. The Bi-metal hole saw can be used to cut into a variety of metals, including aluminum, copper, stainless steel, zinc, wood, and drywall (plaster board). The Bi-metal hole saw is primarily used by electricians, plumbers, machinists, and carpenters. The Bi-metal hole saw features low vibration and even cut due to the variable pitched teeth, strong electron beam welded cup design with a tough alloy body for added durability, knock out hole for plug removal, and depth of cut of 38mm. The Bi-metal hole saw has a long life when used properly within the correct rpm and using a lubricant when cutting into metals.
Bi-metal hole saw
Hole saw diameter: *21mm
Use mandrel: TC17002
Application:
The Bi-metal hole saw's fast cutting power lies behind its HSS (hi-speed steel) manufactured teeth. The teeth have been set to a variable pitch to improve harmonic vibration and to have a better chip clearance.
The hole saw can be used to cut into: - Aluminium
- Copper
- Mild steel (sheet metal)
- Stainless steel (sheet metal)
- Zinc
- Wood
- Drywall (plaster board)
- PVC
The Bi-metal hole saws are primarily used by electricians, plumbers, machinists and carpenters.

- Strong electron beam welded cup design with a tough alloy body for added durability.
- Knock out hole for plug removal.
- Depth of cut: 38mm
- Long life - when used properly within the correct rpm and using a lubricant when cutting into metals.
Lubricant tip: Use paraffin or beeswax when cutting into aluminium. Use CT-90 or a general-purpose lubricating oil when cutting into steel.
