MIBRO's bi-metal hole saws feature a 1-3/4 in cutting depth that cuts through a 2 x 4 in a single pass. The 4/6 variable tooth pitch allows for safe and efficient cutting through metal, plastic, and wood. M3 high-speed steel teeth are electron-beam welded to blade body for strength and consistent quality. Hole saws are vacuum heat treated for consistent blade hardness. They feature a thick heavy-duty backing plate for rigidity and cutting support when cutting uneven surfaces. MIBRO's EZE Slot design allows for quick and easy plug removal on all blades with a diameter of 1 3/4 in (44.45 mm) and larger. Hole saw includes screw-in mandrel and pilot drill. See label for cutting depth and cutting speeds for different materials.

  • 1 3/4 in (44.45 mm) cutting depth cuts through a 2 in (50.8 mm) x 4 in (101.6 mm) surface in one pass.

Q: What size is the pilot bit

a month ago
1 Answer
  • A: Howdy neighbor! The pilot bit included with this Mibro hole saw kit features a standard 1/4-inch diameter to help center your cuts perfectly. The bit sits inside a mandrel that has a 3/8-inch shank, meaning it will fit securely into any standard 3/8-inch or 1/2-inch drill chuck.
