Mk Morse mhs60 Bi-metal Hole Saw 3-3/4 Inches No Arbor

Product Description

The MK MORSE mhs60 is a 3-3/4 inch (95mm) Advanced Bi-Metal Hole Saw designed for demanding cutting applications across metal, wood, and composite materials. It features a heavy-duty 0.050 inch side wall for added rigidity and a 1-15/16 inch cutting depth to handle thicker stock. Sold without an arbor, this hole saw is intended for use with a separately sourced compatible arbor. The unit is manufactured in the USA. It is a standard go-to tool for electricians, plumbers, HVAC technicians, and general contractors who need consistent, clean bores in a range of substrates.

This hole saw is suited for both residential and commercial installation work. It handles conduit knockout cuts, pipe penetrations, junction box openings, and duct collar cutouts. The 3-3/4 inch diameter is a common size for trade work involving larger conduit entries and plumbing rough-in passes through framing. Its bi-metal construction allows use on harder materials where standard carbon-steel hole saws wear prematurely.

Installation Notes

Hole saws are typically installed by electricians, plumbers, and HVAC technicians using a compatible arbor and a corded or cordless drill or drill press. Always secure the workpiece before cutting and use appropriate cutting fluid when boring through metal to extend tooth life. Ensure the drill is powered off and unplugged or the tool battery is removed before mounting or removing the hole saw from the arbor. Wear appropriate eye and hand protection during use.
