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.

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.
