"Hole in One" Hole Saw

A hole saw supplied with a dedicated arbor is always the right match, properly assembled and ready to use. BiMetal by Malco ensures vibration-free cuts in any machinable metal, including tool steels and stainless. A variable 4/6 pitched tooth configuration milled into a high speed steel edge and micro-welded to a shatterproof alloy steel body easily tackles nail embedded wood. A generous 1-7/8-inch (47.6 mm) cup depth allows cuts in wooden studs, joists and door slabs in one pass.
