Morse MHS40 2.5" bi-metal hole saw

The Morse MHS40 is a 2.5 inch (64mm) diameter bi-metal hole saw built for general purpose cutting across stainless steel, machinable metals, wood and plastic. It is suited for trade professionals and serious DIY users who need a single durable cutter for mixed material jobs.

Aggressive positive rake tooth profile

The aggressive positive rake tooth profile is designed to penetrate material easier and faster during operation. A unique side slot increases leverage access for various material thicknesses and eases slug removal after the cut is complete.

Requires separate arbor

One hole saw is supplied per box without an arbor; a separate MA35PSN (139052) or MA45PSN (139069) arbor must be purchased to mount the saw. Performance is optimised when Morse CUTLUBE (121408) is used, and omitting lubricant or using an incorrect arbor are common installation issues.

Questions about this item

How often will the bi-metal teeth on the MHS40 need replacing when cutting stainless steel?

The bi-metal construction resists wear in stainless steel and machinable metals; replace the saw when the aggressive positive-rake teeth no longer penetrate cleanly.

What stops the MHS40 from cutting deeper in thick steel plate?

The 64 mm cutting depth and the separate arbor length limit how far the saw can advance before the slug must be cleared through the side slot.

Does the MHS40 get hot enough to burn the workpiece during a long day of cutting?

Friction heat builds in continuous use; applying Morse CUTLUBE 121408 keeps the teeth and the workpiece cooler while the side slot clears chips.
