Morse MHSG76 4.75" Carbide Grit Hole Saw

The Morse MHSG76 is a 4.75 inch diameter hole saw with a carbide grit edge built for hard or abrasive materials. It cuts cinder block, cast iron, unglazed ceramics, fiberglass and composites. The gulleted cutting edge clears chips while cutting. A separate Morse MA35PSNCT or MA45PSNCT arbor is required for operation.

Sustained cutting in abrasive media

Carbide grit resists wear when the saw runs continuously through cinder block, cast iron or fiberglass. The gulleted edge keeps the kerf clear so heat and dust do not choke the cut. The unique side slot gives leverage for slug removal across various material thicknesses. One hole saw per box.

Arbor fit and slug removal

Installation starts by threading the correct Morse arbor, either MA35PSNCT (139830) or MA45PSNCT (139847), into the saw before chucking. The side slot lets a screwdriver or pry bar pop the slug out without binding. The only common issue is forgetting to order the arbor separately, which stops the job before it begins.

Questions about this item

How much heat or vibration does the 4.75" carbide grit edge create during extended cutting in cast iron or cinder block?

The gulleted cutting edge clears chips continuously, which reduces friction and heat buildup during long cuts in hard materials like cast iron or cinder block.

Which Morse arbor must I already own to mount the MHSG76 hole saw?

A separate arbor is required; compatible Morse models are the MA35PSNCT (139830) or MA45PSNCT (139847).

Will the unique side slot on this 121 mm saw clear slugs when I pair it with an older Morse arbor?

The side slot is designed to increase leverage for easier slug removal across various material thicknesses, independent of the arbor used.
