64 mm Bi-Metal Hole Saw

The Morse MHSA40C is a 64 mm diameter, arbored bi-metal hole saw built for general-purpose cutting. It handles stainless steel, machinable metals, wood and plastic in a single tool. The aggressive positive rake tooth profile penetrates material easier and faster. One saw is supplied per card.

Upgrade from Standard Carbon Steel Saws

This bi-metal construction replaces basic carbon steel saws when cutting mixed material stacks or harder alloys. The jump is worth it when slug removal slows you down; the unique side slot increases leverage access for various thicknesses. Using Morse CUTLUBE (121408) further optimises performance and extends tooth life.

Limits of the Arbored Shank Design

The fixed arbor means the pilot drill and saw body cannot be separated for individual replacement. If the pilot dulls or the shank bends, the whole unit is discarded. The 64 mm diameter also demands a drill chuck capacity that accommodates the shank size; smaller cordless drills may lack the torque to maintain speed in thick stainless steel.

Questions about this item

Does the 2.5" bi-metal hole saw come with an integrated arbor or do I need a separate one?

The MHSA40C is an arbored model with the arbor built in, so no separate arbor purchase is required for the 64 mm cutting diameter.

What is the correct way to fit the pilot drill on this arbored hole saw?

The pilot drill is pre-installed in the fixed arbor; ensure it protrudes past the tooth tips before starting the cut so it centres the 64 mm saw cleanly.

When should I replace the Morse MHSA40C hole saw?

Replace the saw when the bi-metal teeth dull enough to slow cutting in stainless steel, machinable metals, wood or plastic, or if the side slot no longer ejects the slug cleanly.
