Bi-metal hole saws cut round holes in sheet metal, mild steel, aluminium, PVC, plywood and wood. Electricians, plumbers and installers use them for conduit, pipe and panel holes. This collection has single sizes and sets from Makita, Bosch, Ingco, Total, Lotus, Wadfow and more.
How to choose a bi-metal hole saw
- Size: match the hole saw to the pipe, conduit or fitting you are installing. Check the size on the product page.
- Single or set: electrician sets (Makita D-47123, D-63987) cover common conduit sizes, plumber sets (Makita D-47117, D-63971, Wadfow WKJ3491) cover pipe sizes, and general sets such as the Makita D-63993 or Ingco AKH0021 cover both.
- Mandrel and pilot drill: single hole saws need a mandrel (arbor) with a pilot drill. Spare mandrels such as the MaxSell HM-917006 are sold separately.
Use with
Run bi-metal hole saws at low speed in a hand drill or cordless drill, and use cutting oil on steel. For stainless and thick steel, see TCT hole saws. For tile and glass, see diamond hole saws.
All products from KHM Megatools are genuine.
