Morse MHSG32 51mm Carbide Grit Hole Saw

This Morse MHSG32 hole saw features a 51mm diameter carbide grit edge built for hard and abrasive materials. It cuts cinder block, cast iron, unglazed ceramics, fiberglass and composites. The gulleted edge clears chips during the cut while a unique side slot eases slug removal. It is sold individually and requires a separate arbor.

Capacity and headroom

The 51mm carbide grit edge handles tough materials that quickly wear standard bi-metal teeth. It maintains cutting performance through abrasive composites and hard metals where other saws lose their edge. The design works across various material thicknesses thanks to the side slot. A separate Morse arbor must be selected to match the drill and application.

Upgrade path

This saw replaces worn or damaged carbide grit hole saws of the same 51mm size. The jump is worth it when cutting abrasive materials that destroy conventional teeth, or when the side slot feature speeds up slug removal on repetitive jobs. Compatible arbors include Morse MA35PSNCT (139830) or MA45PSNCT (139847).

Questions about this item

Will the MHSG32 51mm carbide grit hole saw fit the Morse MA35PSNCT 139830 arbor I already own?

Yes, the MHSG32 is designed to work with the Morse MA35PSNCT (139830) arbor as well as the MA45PSNCT (139847) model.

How can I verify the MHSG32 is cutting correctly in cinder block or cast iron?

The gulleted edge should clear chips steadily and the side slot lets you lever out the slug cleanly; smooth progress without binding shows it is working as intended.

Does the box include an arbor or must I buy the MA35PSNCT 139830 or MA45PSNCT 139847 separately?

Only one hole saw is in the box; a separate Morse arbor such as the MA35PSNCT (139830) or MA45PSNCT (139847) is required and sold separately.
