Morse MHSG18 Carbide Grit Hole Saw

The Morse MHSG18 is a 1-1/8 inch (29mm) diameter hole saw featuring 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. A gulleted edge design provides chip clearance during the cut. A unique side slot improves leverage access for easier slug removal from various material thicknesses.

Who This Suits and Who Should Look Elsewhere

This tool suits tradespeople and DIY users drilling clean holes in tile, stone, cast iron or composite panels where standard bi-metal teeth would wear quickly. The carbide grit edge handles abrasive surfaces that destroy conventional saws. It is not for buyers who need to cut clean, fast holes in mild steel, stainless steel or thick wood, as grit cutting is slower and leaves a rougher finish in those materials. A separate Morse MA34CT arbor (139809) is required and sold separately.

The Specification That Decides Fit

The single specification that decides fit is the 1-1/8 inch (29mm) cutting diameter; the hole you drill will be exactly this size. Verify your target hole diameter matches before ordering. The saw requires the Morse MA34CT arbor (139809) to mount in your drill chuck, so confirm you have or will buy that specific arbor. One hole saw is included per box.
