Morse MHS52 3.25" bi-metal hole saw

This Morse MHS52 bi-metal hole saw cuts a 3.25 inch diameter hole. It handles stainless steel, machinable metals, wood and plastic. The aggressive positive rake tooth profile penetrates material faster. A unique side slot eases slug removal from various material thicknesses.

General purpose cutting in metal wood plastic

Tradespeople cutting stainless steel, mild steel, wood or plastic will find this saw suited to the task. The bi-metal construction withstands general purpose workshop use. Users needing a complete kit with an arbor included should look elsewhere. Anyone requiring a specialised tooth geometry for a single material type should consider other options.

3.25 inch diameter requires separate arbor

The saw has a 3.25 inch cutting diameter and requires a separate arbor for operation. Compatible arbors include the MA35PSN or MA45PSN models. Morse CUTLUBE is recommended to optimise cutting performance. One hole saw is supplied per box.

Questions about this item

How thick a workpiece can the 3.25" MHS52 hole saw cut through?

The bi-metal blade handles stainless steel, machinable metals, wood and plastic across various thicknesses; the side slot gives extra leverage for slug removal on thicker stock.

Does the MHS52 run hot or load the air tool after hours of cutting?

The aggressive positive-rake tooth profile reduces feed force, keeping heat build-up low and letting the pneumatic tool maintain steady speed during long sessions.

Which Morse arbor must I already have to mount the MHS52?

The saw requires a separate arbor — use the MA35PSN (139052) or MA45PSN (139069) — so one of those must be on hand before the saw will fit your tool.
