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 (plasterboard) PVC The Bi-metal hole saws are primarily used by electricians, plumbers, machinists and carpenters. 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. 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.
