  • Cuts stainless steel, wood and plastic with one bi-metal saw
  • Aggressive positive-rake teeth penetrate material faster for smoother drilling
  • Unique side slot improves leverage and eases slug removal
  • Requires separate arbor MA35PSN or MA45PSN for secure mounting
  • Use Morse CUTLUBE 121408 to optimise cutting performance and life

Morse MHS88 5.5" bi-metal hole saw

The Morse MHS88 is a 5.5 inch (140mm) diameter bi-metal hole saw built for general purpose cutting. It handles stainless steel, machinable metals, wood and plastic. The aggressive positive rake tooth profile is designed to penetrate material easier and faster. One hole saw is supplied per box.

Arbor and lubrication requirements

A separate arbor is required for operation; compatible options include the MA35PSN (139052) or MA45PSN (139069). The unique side slot increases leverage access across various material thicknesses, easing slug removal. To optimise performance, consider using Morse CUTLUBE (121408) during cutting tasks.

Suited for general purpose cutting

This hole saw suits tradespeople and DIY users needing a single 5.5 inch bi-metal cutter for mixed materials. It is not for buyers who need an arbor included in the package or those requiring a complete kit with multiple diameters. Users without access to a compatible Morse arbor should look elsewhere.

Questions about this item

How thick a workpiece can the 140 mm bi-metal hole saw cut before the side slot loses leverage?

The unique side slot is designed to ease slug removal across various material thicknesses, letting the aggressive positive rake teeth maintain cutting speed without a published depth limit.

What heat or vibration should I expect when running the MHS88 all day in stainless steel?

Bi-metal construction dissipates heat during extended cuts in stainless steel, machinable metals, wood and plastic, while the positive rake tooth profile reduces vibration and cutting force.

Which Morse arbor must I already own to mount the 5.5 inch hole saw?

A separate arbor is required; compatible models are MA35PSN (139052) or MA45PSN (139069).
