Morse MHS22 Bi-Metal Hole Saw

The Morse MHS22 is a 1-3/8 inch bi-metal hole saw built for general-purpose cutting. It handles stainless steel, machinable metals, wood and plastic with an aggressive positive rake tooth profile that penetrates material faster. A unique side slot improves leverage for slug removal across various material thicknesses. One hole saw is supplied per box.

Trade users cutting mixed materials

This hole saw suits electricians, plumbers and maintenance crews who need a single cutter for metal, wood and plastic on site. The bi-metal construction resists tooth breakage in tough alloys while staying sharp in softer stock. Buyers who need a complete kit with an arbor included or who only cut one material type should look at dedicated sets or single-material saws.

35 mm diameter with separate arbor required

The cutting diameter is 35 mm, identified by model number MHS22 and part reference 177221. A separate Morse arbor must be purchased; compatible options are the M35 (139045), MA35PSN (139052) or MA45PSN (139069). Using Morse CUTLUBE (121408) is recommended to optimise cutting performance and tool life.

Questions about this item

How does the 35 mm diameter affect cutting depth on thick stainless steel?

The 35 mm diameter determines the hole size, not the cutting depth; the saw body depth sets the maximum material thickness you can cut in one pass.

What temperature rise should I expect when running this hole saw continuously on steel?

Heat depends on feed pressure, cutting fluid and material; using Morse CUTLUBE 121408 helps control temperature during prolonged cuts.

Which arbor must I already own to mount this hole saw?

You need a separate Morse arbor — M35 139045, MA35PSN 139052 or MA45PSN 139069 — to attach the saw to your drill.
