Morse MHS345 55mm Bi-Metal Hole Saw

The Morse MHS345 is a 55mm diameter bi-metal hole saw built for general purpose cutting across stainless steel, machinable metals, wood and plastic. Its aggressive positive rake tooth profile is designed to penetrate material more easily and quickly. A unique side slot improves leverage access for various material thicknesses and helps with slug removal. One hole saw is supplied per box.

Compatibility check before ordering

This hole saw requires a separate arbor which is not included in the box. Compatible Morse arbors are the MA35PSN (139052) or MA45PSN (139069). Verify that your power tool accepts one of these arbor models before purchase. For optimal cutting performance the manufacturer suggests using Morse CUTLUBE (121408).

Who this suits and who should look elsewhere

This tool suits tradespeople and DIY users needing a single 55mm bi-metal saw for mixed materials including stainless steel and wood. It is not for buyers who need an arbor included in the package or who require a different cutting diameter. Users without a compatible Morse arbor or a suitable power tool should look at other options.
