Product identity

The Morse MHS64 is a 4-inch bi-metal hole saw built for general-purpose cutting across stainless steel, machinable metals, wood and plastic. Its aggressive positive-rake tooth profile penetrates material faster while the unique side slot improves leverage for easier slug removal. One saw is supplied per box.

Build integration

The saw requires a separate arbor; compatible options are the MA35PSN or MA45PSN. Using Morse CUTLUBE helps optimise cutting performance and tool life. The side slot design eases slug extraction across various material thicknesses, reducing downtime during repetitive drilling tasks.

Target user

Suits tradespeople and DIYers needing a single large-diameter cutter for mixed-material jobs who already own or can source a compatible arbor. Not suited for buyers who need an arbor included in the package or who require a multi-size kit for varied hole diameters.

Questions about this item

How fast does the 102 mm diameter bimetal blade wear when cutting stainless steel all day?

The aggressive positive rake tooth profile is designed to penetrate stainless steel and other machinable metals faster, reducing wear during extended cutting sessions.

Does the saw body get hot or vibrate loudly during continuous operation?

The bimetal construction dissipates heat while the unique side slot improves leverage and eases slug removal, helping keep vibration and temperature manageable during long runs.

Which Morse arbor must I already have to mount this 4 inch hole saw?

A separate arbor is required; compatible models are the MA35PSN (139052) or MA45PSN (139069) depending on your drill chuck size.
