Hole saw bi-metal M.K. Morse 60 mm x 2 – 3/8" for metal cutting, MORSE-PTA-MHS38

Bi-metal hole saw by M.K. Morse, 60 mm diameter with a 2 mm wall thickness and a 3/8" connection. This cutting tool is designed to produce clean circular holes in metal and other hard materials when used with a suitable arbor and a drill. The bi-metal construction combines high-speed steel teeth welded to a flexible alloy body to balance cutting performance and resistance to breakage, making the saw suitable for workshop and industrial metalworking tasks.

Advantages

The bi-metal design offers long tool life and improved resistance to tooth wear compared with standard carbon-steel saws. A thin 2 mm wall reduces cutting resistance and lowers the required drilling torque while maintaining structural stability for accurate hole geometry. The standard 3/8" connection ensures compatibility with common arbors and drill chucks. Tooth geometry and material selection are optimised for cutting ferrous and non-ferrous metals, providing consistent chip evacuation and clean hole edges.

Suitable for

• Cutting circular holes in steel and stainless steel sheets
• Creating openings in non-ferrous metals such as aluminium and copper
• Workshop fabrication and maintenance tasks
• Industrial metalworking where repeated, accurate holes are required

Key specifications

• Diameter: 60 mm
• Wall thickness: 2 mm
• Shank / connection: 3/8"
• Material: bi-metal (HSS teeth welded to alloy body)
• Intended use: metal cutting and hard material cutting

How to use

Mount the hole saw onto a compatible arbor with a 3/8" connection and secure it in the drill chuck. Mark the centre of the hole, use a pilot drill if required to guide the saw, and position the pilot before starting. Operate the drill at a moderate speed appropriate for the material, apply steady feed pressure, and avoid excessive side loads. Periodically withdraw the saw to clear chips and to allow cooling; use cutting lubricant when working with steel or stainless materials to extend tool life and maintain cutting performance.

Usage recommendations

For best results when cutting metals, use a suitable cutting fluid, maintain steady feed without forcing the tool, and ensure the arbor and pilot are straight and secure. Replace the saw if excessive tooth wear or damage is observed to maintain hole accuracy and operator safety.
