Morse MHS315 Bi-Metal Hole Saw 1 15/16

The Morse MHS315 is a bi-metal hole saw with a 50 mm cutting diameter, built for general-purpose drilling in stainless steel, machinable metals, wood and plastic. Its aggressive positive-rake tooth profile cuts faster with less effort. A separate arbor such as the MA35PSN or MA45PSN is required for operation.

Thermals Noise Power

Hand-operated hole saws generate heat only at the cutting interface; the bi-metal construction resists heat buildup during extended cuts in metal. No motor, fan or electrical draw is involved, so noise levels depend entirely on the drill or power tool driving the saw. Using Morse CUTLUBE cutting fluid helps control temperature and prolongs tooth life.

50 mm Diameter Bi-Metal Construction

The 50 mm diameter determines the exact hole size this saw produces; it cannot cut larger or smaller openings. The bi-metal tooth material handles mixed-material jobs but is not suited for carbide-only applications such as hardened steel or abrasive composites. Buyers needing different diameters or a built-in arbor must select another model.

Questions about this item

How do I install the MHS315 hole saw and which step is often missed?

Fit the separate MA35PSN or MA45PSN arbor into the saw's side slot, tighten the set screw fully, then apply Morse CUTLUBE before cutting.

What maintenance or replacement will the 50 mm bi-metal saw need later?

The teeth dull with use; replace the saw when cutting slows or the aggressive positive rake profile no longer penetrates material cleanly.

What limit appears first during sustained cutting with this hole saw?

Heat buildup in the bi-metal body reduces cutting speed; using Morse CUTLUBE extends the run before the saw must cool.
