Morse MHSG68 Carbide Grit Hole Saw 4.25

The Morse MHSG68 is a 4.25 inch carbide grit hole saw built for cutting hard or abrasive materials such as cinder block, cast iron, unglazed ceramics, fiberglass and composites. It is suited for trade professionals and serious DIY users who need clean holes in those specific substrates.

4.25 inch diameter and carbide grit edge

The single specification that decides fit is the 4.25 inch (108 mm) cutting diameter combined with a carbide grit gulleted edge. This size and tooth geometry determine whether the saw matches the required hole size and the material hardness on the job.

Separate arbor required for operation

The saw ships alone and needs a compatible Morse arbor such as the MA35PSNCT (139830) or MA45PSNCT (139847) to function. The unique side slot design improves leverage for slug removal across various material thicknesses once the correct arbor is fitted.

Questions about this item

What does the 4.25 inch diameter mean when I am cutting a hole?

The saw produces a finished hole 4-1/4 inches (108 mm) across, sized for pipe, conduit or ductwork that matches that diameter.

What arbor standard does this hole saw use and what does it limit?

It requires a separate Morse arbor — MA35PSNCT (139830) or MA45PSNCT (139847) — so the shank size and thread of those arbors determine which drill chucks it fits.

What physical clearance do I need to mount and run this saw?

The gulleted carbide-grit edge and side slot need enough drill length for the arbor plus the saw body, and the slot allows slug removal through the side of the cut.
