## Long description

M.K. Morse Advanced Bi-Metal hole saw, 140 mm (5-1/2") diameter, is a bi-metal cutting tool designed for making large diameter holes in a variety of materials. The combination of high-speed steel teeth and flexible alloy backing provides enhanced durability and heat resistance during sustained cutting operations. Intended for use with a compatible arbor and pilot drill, this hole saw is suitable for tasks where long life and reliable performance are required.
Advantages
The bi-metal construction balances toughness and cutting-edge retention, reducing tooth breakage and extending service life compared with standard carbon steel hole saws. Heat-resistant properties help maintain cutting performance during extended work periods and when drilling harder materials. The 140 mm diameter delivers a clean, consistent cut for large openings while remaining compatible with commonly available arbors and pilot drills.
Suitable for
 Cutting large diameter holes in metal sheets and thin steel
 Creating openings in wood and plywood for installations
 Drilling through plastic and composite panels
 HVAC ductwork openings, electrical conduit and junction box installation
 Plumbing penetrations and general construction work
Key specifications
 Diameter: 140 mm (5-1/2")
 Material: bi-metal (high-speed steel teeth bonded to alloy backing)
 Cutting edge: hardened HSS teeth for wear resistance
 Application: suitable for metal, wood and plastic with appropriate arbor
 Recommended use: with compatible arbor and pilot drill for stable drilling
How to use
Secure a suitable arbor with a compatible pilot drill into your drill or driver, ensuring the arbor and hole saw are tightened to prevent wobble. Mark the center of the intended hole and position the pilot bit on the mark. Start drilling at low to moderate speed, applying steady, even pressure to allow the teeth to cut and clear chips. For metal or harder materials, use cutting lubricant and reduce speed to control heat buildup. After cutting, back the hole saw away from the material while the tool is still rotating to help clear the cut and prevent jamming.
Usage recommendations
Use appropriate personal protective equipment (eye protection, gloves) and secure the workpiece before drilling. Match the arbor and pilot drill shank to the hole saw and drill press or hand drill specifications. For extended life when cutting metal, apply cutting fluid and avoid excessive speed and pressure.
