Morse MHS30 1-7/8" Bi-Metal Hole Saw

The Morse MHS30 is a 48 mm diameter bi-metal hole saw built for general-purpose cutting in stainless steel, machinable metals, wood and plastic. Its aggressive positive-rake tooth profile penetrates material faster, while a unique side slot improves leverage for slug removal across various thicknesses. One hole saw is supplied per box, and a separate arbor must be purchased to mount it.

Who this suits and who should look elsewhere

Tradespeople and DIY users who need a single 1-7/8" cutter for mixed-material jobs will find the MHS30 a practical choice, especially when paired with Morse M35, MA35PSN or MA45PSN arbors and CUTLUBE lubricant. Buyers who want a complete kit with an included arbor, or who require multiple diameters in one purchase, should look at other options.

The specification that decides fit

The critical figure is the 48 mm (1-7/8") cutting diameter; if your project demands a different hole size, this saw will not work. You must also confirm compatibility with one of the specified Morse arbors (M35, MA35PSN or MA45PSN) before ordering, as no arbor is included in the box.

Questions about this item

How do I install the MHS30 hole saw and what step is often missed?

Mount the MHS30 onto a separate Morse M35 (139045), MA35PSN (139052) or MA45PSN (139069) arbor; the step people miss is securing the arbor firmly in the drill chuck before cutting.

What maintenance or replacement will the MHS30 need later?

The bi‑metal teeth dull with use; replace the hole saw when cutting slows in stainless steel, machinable metals, wood or plastic.

What limit appears first during sustained use of the MHS30?

Heat buildup in the 48 mm diameter blade reduces cutting speed; applying Morse CUTLUBE (121408) delays this limit.
