5.5" Carbide Grit Hole Saw

The Morse MHSG88 is a 5.5 inch diameter carbide grit hole saw built for pneumatic and power tool use. Its gulleted cutting edge clears chips while cutting through hard or abrasive materials such as cinder block, cast iron, unglazed ceramics, fiberglass and composites. A unique side slot improves leverage and eases slug removal across various material thicknesses. One hole saw is supplied per box.

Trades cutting abrasive materials

This accessory suits plumbers, electricians and general contractors who need clean holes in masonry, metal or composite surfaces. It is not intended for wood or standard metal cutting where a bi-metal tooth design would be more efficient. Buyers who require an integrated arbor or a complete kit should look elsewhere because a separate Morse arbor must be purchased. The saw is sold individually without mounting hardware.

Requires separate Morse arbor

The single specification that decides fitment is the mandatory separate arbor; this hole saw will not mount without a compatible Morse MA35PSNCT or MA45PSNCT arbor. Confirm the correct arbor for your tool before ordering. No other mounting system is supported by this model.

Questions about this item

Does the Morse MHSG88 hole saw come with an arbor or must one be purchased separately?

The box contains one 5.5" carbide grit hole saw. An arbor is not included; select Morse MA35PSNCT (139830) or MA45PSNCT (139847) for your drill.

Which Morse arbor — MA35PSNCT or MA45PSNCT — matches the MHSG88 for my drill?

Both arbors fit the MHSG88; choose MA35PSNCT for smaller chucks or MA45PSNCT for larger chucks depending on your drill capacity.

How does the 5.5" diameter perform when cutting cast iron or cinder block in practice?

The 140mm carbide grit edge clears chips through gullets and the side slot eases slug removal, giving steady progress in hard abrasive materials.
