Morse MHSG92 Carbide Grit Hole Saw
The Morse MHSG92 is a 5.75 inch (146 mm) diameter hole saw with a carbide grit edge. It is built for tradespeople cutting hard or abrasive materials such as cinder block, cast iron, unglazed ceramics, fiberglass and composites. A separate arbor is required for operation.
Sustained cutting in abrasive media
The gulleted cutting edge clears chips continuously while cutting, reducing heat buildup during extended use. The unique side slot provides leverage access across various material thicknesses, making slug removal easier throughout a long job. Carbide grit maintains its cutting action longer than toothed blades in these applications.
Upgrading from bi-metal hole saws
This saw replaces standard bi-metal hole saws when the material dulls teeth quickly or causes excessive vibration. The jump is worth it for installers who regularly cut masonry, cast iron or composites and need faster slug ejection without binding. It does not suit wood or thin metal where a toothed blade cuts cleaner.

Questions about this item
How much heat does the 5.75" carbide grit edge generate during continuous cutting in cast iron?
The gulleted cutting edge clears chips efficiently, which helps dissipate heat during extended use on hard materials like cast iron.
Which Morse arbor must I already own to mount the MHSG92 hole saw?
A separate Morse arbor is required; compatible models are MA35PSNCT (139830) or MA45PSNCT (139847).
Will the 146mm diameter saw fit through the side slot of my older Morse arbor for slug removal?
The unique side slot on this saw is designed to increase leverage and ease slug removal across various material thicknesses when used with compatible Morse arbors.
