General-purpose cutting tool
The Morse MHSA48C is a 3 inch (76mm) diameter bi-metal hole saw designed for general purpose use. It cuts a wide range of materials including stainless steel, machinable metals, wood and plastic. The tool features an aggressive positive rake tooth profile for easier penetration. An integrated arbor and side slot simplify slug removal across various material thicknesses.
Bi-metal construction and tooth geometry
The bi-metal body combines high-speed steel teeth with a flexible alloy backing for durability in mixed-material applications. Positive rake teeth reduce the force required to start and maintain a cut. The unique side slot provides leverage access to eject the slug without prying. One hole saw is supplied per card ready for immediate use.
Sustained cutting in tough alloys
Under continuous load in stainless steel or thick machinable metals, the bi-metal edge resists tooth strippage and heat buildup better than carbon steel alternatives. The side slot prevents the slug from binding deep in the kerf, maintaining cutting efficiency over repeated holes. Morse CUTLUBE 121408 is recommended to further extend tool life during prolonged operations.

Questions about this item
How do I install the Morse MHSA48C hole saw and what step is often missed?
The saw is arbored, so mount it directly into the drill chuck. The step people miss is applying Morse CUTLUBE (121408) before cutting metal to reduce heat and extend tooth life.
What maintenance or replacement will this bi-metal hole saw need later?
The bi-metal teeth dull with use; replace the saw when cutting slows or the slug binds. The side slot helps remove slugs, but worn teeth cannot be sharpened economically.
What limit appears first during sustained use in stainless steel?
Heat buildup at the aggressive positive-rake tooth profile is the first limit; without cutting lubricant the teeth overheat and lose hardness quickly.
