Morse MHSG80 5" Carbide Grit Hole Saw

SKU CH-HASC-98KEA

Cuts hard abrasive materials such as cinder block, cast iron and fiberglass with a gulleted 127 mm carbide grit edge and side slot for easy slug removal

  • Cuts hard abrasive materials with carbide grit edge
  • 127 mm diameter suits large-diameter applications
  • Gulleted edge clears chips during cutting
  • Side slot eases slug removal from thick stock
  • Requires Morse MA35PSNCT or MA45PSNCT arbor (not included)

Product Identity

The Morse MHSG80 is a 5 inch (127mm) diameter carbide grit hole saw built for cutting hard and abrasive materials such as cinder block, cast iron, unglazed ceramics, fiberglass and composites. It is intended for tradespeople and maintenance crews who need clean holes in tough substrates.

Build and Mounting

A gulleted cutting edge provides chip clearance during the cut, while a unique side slot improves leverage for removing the slug across various material thicknesses. The saw requires a separate arbor; compatible Morse models are MA35PSNCT (139830) or MA45PSNCT (139847), sold separately.

Practical Limits

Carbide grit excels on abrasive and brittle materials but is not suited for fast cutting in wood, plastic or thin sheet metal where a toothed bi-metal saw would be more efficient. The tool is sold individually without an arbor, so buyers must source the correct Morse arbor before use.

Questions about this item

What size arbor does the 5" carbide grit hole saw require?

Use Morse MA35PSNCT (139830) or MA45PSNCT (139847) arbors; the 35 and 45 refer to the arbor series that fit this 127 mm diameter saw.

How deep can the MHSG80 cut before the side slot is needed for slug removal?

The gulleted edge clears chips during the cut; the unique side slot provides leverage to eject the slug once the saw penetrates through the material thickness.

Does the carbide grit hole saw include a pilot drill bit for starting the cut?

No, the box contains only the 5" hole saw; a separate Morse arbor with its own pilot bit must be purchased and fitted before use.
