Bi-Metal Hole Saw for General Purpose Cutting

The Morse MHSA52C is a 3.25 inch bi-metal hole saw built for general purpose use. It cuts stainless steel, machinable metals, wood and plastic with an aggressive positive rake tooth profile. The design targets professionals and DIY users who need a single, durable cutter for mixed materials.

Fits Standard Arbors and Eases Slug Removal

The saw comes arbored, so it mounts directly onto a compatible arbor without a separate adapter. A unique side slot improves leverage access across various material thicknesses, making slug ejection simpler. The tool requires a drill or drill press capable of accepting the arbor shank.

One Saw Per Card with Cutting Lubricant Option

Each card contains one hole saw identified by part number 116527. Morse recommends using CUTLUBE cutting fluid, part number 121408, to optimise performance and extend blade life. No additional accessories, pilot bits or storage cases are included in the package.

Questions about this item

How deep can the 3.25" bi-metal hole saw cut before the side slot limits slug removal?

The unique side slot provides leverage access for various material thicknesses, easing slug removal during deep cuts in stainless steel, wood or plastic.

Does the aggressive positive rake tooth profile generate excessive heat when cutting stainless steel all day?

The aggressive tooth profile penetrates material easier and faster, reducing friction and heat buildup during extended cutting sessions in machinable metals.

What arbor or mandrel must I already own to mount the MHSA52C hole saw?

The hole saw is arbored, meaning the arbor is built in, so no separate mandrel is required for use with a standard drill chuck.
