2-1/2 Inch Bi-Metal Hole Saw

The L.H. DOTTIE VP40 is a bi-metal hole saw with a variable pitch tooth design. It suits electricians, plumbers and maintenance technicians who need clean holes in metal, wood or plastic. The 2-1/2 inch diameter matches common conduit and pipe-entry sizes.

Variable Pitch Cutting Limits

The variable pitch pattern reduces vibration and improves chip clearance during drilling. Cutting depth is limited by the saw cup length, so thick workpieces may require pilot-hole relief. Heat buildup in stainless steel or hardened alloys will dull teeth faster than in mild steel.

Arbor Mounting and Common Issues

The saw attaches to a standard quick-change arbor through the centre hole. Installers must ensure the arbor shank matches their drill chuck capacity. A loose setscrew or missing pilot bit causes wobble and uneven wear. Always clear swarf between cuts to prevent binding.
