“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.

All BiMetal Hole Saw sizes feature 4/6 VARIABLE PITCH TEETH for aggressive cutting in all machinable  materials.


High Speed 1/4-inch (6.4 mm) replacement pilot drill bit fits both original Hole-in-One hole saw with built-in arbor, and current 2-piece Hole-in-One with separate arbor.

Features

  • Supplied with arbor.
  • Shatter-proof BiMetal by Malco construction.
