Morse MHSG14 7/8" 22mm carbide grit hole saw

Morse MHSG14 7/8" Carbide Grit Hole Saw

The Morse MHSG14 is a 7/8 inch (22mm) diameter hole saw with a carbide grit cutting edge. It is built for cutting hard or abrasive materials such as cinder block, cast iron, unglazed ceramics, fiberglass and composites. The gulleted edge clears chips during the cut and a side slot improves leverage for slug removal across various material thicknesses. One hole saw is supplied per box.

Trade users cutting masonry, metal or composites

This saw suits plumbers, electricians and contractors who need clean holes in abrasive or hard surfaces where standard bi-metal teeth wear quickly. It is not for wood or soft plastics where a toothed blade cuts faster and cleaner. Buyers who need an immediate, ready-to-use tool should note that a separate Morse MA34CT arbor (139809) is required and not included. Workers who only occasionally drill soft materials will find a conventional hole saw more economical.

Carbide grit edge for abrasive materials

The carbide grit edge is the single specification that determines whether this is the right part. It resists the wear caused by cinder block, cast iron, unglazed ceramics, fiberglass and composites that destroys conventional teeth. If the job involves only wood, plastic or thin sheet metal, a standard bi-metal hole saw will cut faster and cost less. Choose this saw only when the material being cut demands the abrasion resistance of carbide grit.
