1" Carbide Grit Hole Saw

The Morse MHSG16 is a 1 inch (25mm) diameter hole saw with a carbide grit edge. It is designed for cutting hard or abrasive materials such as cinder block, cast iron, unglazed ceramics, fiberglass and composites. Professional tradespeople and maintenance crews use it for clean holes in tough substrates. One saw is supplied per box.

Installation requires a separate arbor

A Morse MA34CT arbor (part number 139809) must be purchased separately to mount this hole saw. The unique side slot improves leverage for slug removal across various material thicknesses. Forgetting the correct arbor is the most common issue, leaving the saw unusable until the matching part arrives. The gulleted cutting edge clears chips during the cut.

Carbide grit suits abrasive materials only

This cutting edge works on hard, abrasive surfaces but is not intended for general-purpose wood or metal cutting. The carbide grit wears differently than toothed blades and requires steady pressure and appropriate speed. Buyers needing fast cuts in soft wood or standard mild steel should choose a different hole saw type. The 1 inch diameter fixes the hole size.
