4.5" Carbide Grit Hole Saw

The Morse MHSG72 is a 4.5 inch carbide grit hole saw built for cutting hard and abrasive materials. It suits trade professionals and maintenance crews who regularly drill cinder block, cast iron, unglazed ceramics, fiberglass and composites. The 114mm diameter matches common large-bore requirements in construction and industrial settings.

Gulleted Edge and Side Slot

A gulleted cutting edge clears chips during the cut to maintain steady progress through dense material. The unique side slot improves leverage access across various material thicknesses and eases slug removal after the hole is completed. One hole saw is supplied per box; a separate Morse arbor such as the MA35PSNCT or MA45PSNCT must be purchased separately to mount the saw.

Arbor-Dependent Compatibility

The saw cannot operate without a compatible Morse arbor, so users must verify they have or obtain the correct model before starting work. Carbide grit excels on abrasive substrates but is not intended for general-purpose wood or metal cutting where bi-metal teeth would be faster. Buyers who need an all-in-one kit or a different diameter should look elsewhere.
