Morse MHSG46 Carbide Grit Hole Saw

The Morse MHSG46 is a 2-7/8 inch diameter hole saw with a carbide grit cutting edge. It is engineered for cutting hard or abrasive materials such as cinder block, cast iron, unglazed ceramics, fiberglass and composites. A gulleted edge design provides chip clearance during operation. A separate arbor must be purchased to operate this tool.

Suited for abrasive material cutting.

This hole saw suits tradespeople and DIYers drilling clean holes in masonry, cast iron or composite materials where standard bi-metal teeth wear quickly. The carbide grit edge resists abrasion in these specific applications. It is not for buyers who need fast cutting in wood, plastics or mild steel. It is also not for users who do not already own or plan to buy a compatible Morse arbor.

Requires Morse MA35PSNCT or MA45PSNCT arbor

The single specification that decides fit is the mandatory arbor requirement. This hole saw will not function without a Morse MA35PSNCT (139830) or MA45PSNCT (139847) arbor, sold separately. Confirm your drill chuck accepts the chosen arbor shank before ordering. One hole saw is supplied per box.

Questions about this item

Which Morse hole-saw size should I pick for a 73 mm cut?

The MHSG46 is the 2-7/8 inch (73 mm) diameter model; choose it when that exact hole size is required.

How does the carbide grit edge perform in cast iron or fiberglass?

The grit edge cuts hard, abrasive materials such as cast iron, cinder block, unglazed ceramics, fiberglass and composites while the gulleted design clears chips during the cut.

What arbor fits this saw and what does the side slot do?

Use Morse MA35PSNCT (139830) or MA45PSNCT (139847); the unique side slot gives extra leverage for easier slug removal across various material thicknesses.
