Morse MHS56 3.5" bi-metal hole saw

This Morse MHS56 bi-metal hole saw cuts a 3.5 inch (89mm) diameter hole. It is built for general purpose cutting across stainless steel, machinable metals, wood and plastic. The aggressive positive rake tooth profile penetrates material easier and faster. A unique side slot improves leverage for slug removal across various material thicknesses.

Who this suits and who should look elsewhere

Trade professionals and DIY users needing a single 3.5 inch hole saw for mixed materials will find this tool suitable. It requires a separate arbor such as the MA35PSN or MA45PSN to operate. Buyers who need an arbor included or a different cutting diameter should look at other options.

The specification that decides fit

The 3.5 inch cutting diameter is the critical specification for this hole saw. Verify this matches the required hole size for your project before purchase. The bimetal construction and tooth profile support the listed material range. A separate arbor purchase is mandatory for installation.

Questions about this item

What size arbor is needed for the Morse MHS56 3.5" hole saw?

The Morse MHS56 requires a separate arbor. Compatible models are the MA35PSN (139052) or MA45PSN (139069) depending on your drill chuck size.

How do I install the Morse MHS56 hole saw onto the arbor, and what step is often missed?

Thread the hole saw onto the arbor until the drive pins engage the side slots. The step often missed is tightening the set screw firmly to prevent the saw from spinning loose during cutting.

When should I replace the Morse MHS56 bi-metal hole saw?

Replace the saw when the teeth become dull, chipped, or when cutting speed drops noticeably. Using Morse CUTLUBE (121408) during operation extends tooth life significantly.
