Morse MHSG12 3/4" Carbide Grit Hole Saw

This Morse MHSG12 hole saw features a 3/4 inch (19mm) diameter carbide grit edge designed for cutting hard and abrasive materials. It handles cinder block, cast iron, unglazed ceramics, fiberglass, and composites effectively. The gulleted cutting edge provides chip clearance during operation. A separate Morse MA34CT arbor is required for use.

Trade professionals cutting masonry, metal.

This tool suits electricians, plumbers, and contractors needing clean holes in tough materials like cast iron or fiberglass. The unique side slot improves leverage and eases slug removal across various material thicknesses. It is not intended for wood or standard bi-metal cutting applications. Buyers without a compatible Morse MA34CT arbor must purchase one separately.

3/4 inch diameter capacity

The 19mm cutting diameter handles standard conduit and pipe entry sizes in hard materials. Carbide grit provides extended life in abrasive media where bi-metal teeth wear quickly. The single-unit packaging means multiple sizes require separate purchases. Maximum cutting depth is limited by the hole saw body length and arbor engagement.

Questions about this item

Does the Morse MHSG12 require a separate arbor to operate?

Yes, this carbide grit hole saw needs a Morse MA34CT arbor, part number 139809, which is sold separately.

Will this 3/4 inch hole saw fit the arbors I already own?

It only works with the Morse MA34CT arbor, so older arbors from other brands or models will not fit.

How can I confirm the Morse MHSG12 is cutting correctly after installation?

The gulleted edge should clear chips while cutting hard materials like cast iron or fiberglass, and the side slot lets you remove the slug easily.
