## Summary description

Bi-metal hole saw by M.K. Morse with a 111 mm cutting diameter and 4 mm blade thickness, fitted for a 3/8" arbor. Designed for cutting holes in metal and mixed materials, the bi-metal construction combines HSS cutting edge with a flexible backing for durability and resistance to heat. Suited for trade and workshop use where precise circular cuts and long tool life are required.

## Long description

Bi-metal hole saw M.K. Morse 111 mm x 4 mm with a 3/8" arbor is a circular cutting tool designed for making precise round holes in metal and mixed materials. The bi-metal construction pairs a high-speed steel (HSS) cutting edge with a flexible backing, providing a balance of hardness for cutting and toughness against shock and bending. The 111 mm cutting diameter and 4 mm blade thickness suit trade and workshop applications where repeatable, clean hole cutting is required.
Advantages
The bi-metal design increases wear resistance and heat tolerance compared with standard carbon steel saws, extending service life under continuous use. A 4 mm blade thickness gives structural stability for even cutting, while the HSS teeth maintain sharpness over many cuts. Compatibility with a 3/8" arbor enables use with common drill motors and arbor systems in professional and semi-professional environments.
Suitable for
 Cutting circular holes in thin to medium gauge metal sheets
 Creating openings in mixed-material assemblies (metal backed with softer materials)
 Trade and workshop tasks requiring consistent hole diameters for fittings and fixtures
Key specifications
 Cutting diameter: 111 mm
 Blade thickness: 4 mm
 Tooth material: high-speed steel cutting edge
 Construction: bi-metal (HSS cutting edge bonded to flexible backing)
 Arbor interface: 3/8" compatible
How to use
Fit the hole saw onto a compatible 3/8" arbor and secure it to the drill according to the arbor manufacturer's instructions. Mark the centre point of the intended hole and, if available, use a pilot drill to guide the arbor. Start drilling at low speed to establish the pilot and then increase speed as appropriate for the material. Apply steady, moderate pressure and use coolant or cutting fluid when cutting metal to reduce heat buildup and prolong blade life. After completing the cut, allow the tool to cool before handling.
Usage recommendations
Use cutting fluid when working with steel or other hard metals, avoid excessive side loads, and replace the hole saw if teeth become visibly worn or damaged to maintain cut quality and safety.
