Morse MHSG44 2.75" Carbide Grit Hole Saw

The Morse MHSG44 is a 2.75 inch (70mm) diameter hole saw with a carbide grit cutting edge. It is built for tradespeople cutting hard or abrasive materials such as cinder block, cast iron, unglazed ceramics, fiberglass and composites.

Arbor requirement and chip clearance

This hole saw requires a separate Morse arbor, specifically the MA35PSNCT (139830) or MA45PSNCT (139847) models. A gulleted cutting edge provides chip clearance during the cut, while a unique side slot improves leverage for slug removal across various material thicknesses.

Carbide grit edge for abrasive materials

The carbide grit edge is the single specification that determines suitability; it enables cutting of hard, abrasive substrates that destroy conventional bi-metal teeth. Buyers needing clean holes in wood, plastic or thin sheet metal should select a different tooth geometry.

Questions about this item

Which Morse carbide-grit hole saw diameter should I select for a 2.75" cut?

The MHSG44 is the only 2.75" (70 mm) diameter model listed, so choose this one when you need that exact hole size.

What does the 2.75" diameter mean when the saw is mounted on a drill?

It produces a finished hole of 2-3/4 inches (70 mm) in hard or abrasive materials such as cast iron, cinder block, fiberglass and unglazed ceramics.

Which arbor fits the MHSG44 and what does it limit?

Use Morse MA35PSNCT (139830) or MA45PSNCT (139847); the separate arbor requirement means the hole saw cannot operate without one of those two arbors.
