3.25" Carbide Grit Hole Saw

The Morse MHSG52 is a 3.25 inch carbide grit hole saw built for cutting hard and abrasive materials. It handles cinder block, cast iron, unglazed ceramics, fiberglass and composites. The tool suits tradespeople and maintenance crews who need clean holes in tough substrates. One saw is supplied per box.

Gulleted Edge and Side Slot Design

A gulleted cutting edge clears chips while the saw advances, reducing binding in dense material. A unique side slot improves leverage access across various material thicknesses and eases slug removal after the cut. The saw requires a separate Morse arbor, compatible with the MA35PSNCT or MA45PSNCT models. No arbor is included in the package.

Replaces Standard Bi-Metal Saws for Abrasive Work

This carbide grit saw replaces conventional bi-metal hole saws when the workpiece is too hard or abrasive for toothed blades. The upgrade is worth it for repeated cuts in cast iron, masonry or composite panels where tooth wear would be rapid. It is not for wood, thin sheet metal or general-purpose cutting where a toothed saw is faster and cheaper.
