## Long description

The Hole saw M.K. Morse Advanced Bi-Metal 146 mm (5-3/4") is a bi-metal hole saw designed for cutting large-diameter openings in metal and mixed construction materials. Intended for use with standard drills and compatible arbors, this two-material design combines a high-strength tooth edge with a flexible backing to resist chipping and breakage during aggressive cutting. The 146 mm diameter makes it suitable for creating precise holes for pipes, ducts, wiring and other installations in plumbing, electrical and HVAC work.
Advantages
This bi-metal hole saw offers enhanced durability through a combination of hardened cutting teeth and a resilient body that tolerates cyclic stress. The tooth geometry and material selection provide improved cutting life in ferrous and non-ferrous metals compared with standard carbon-steel saws. The saw can be used with common drill speeds and arbors, giving straightforward compatibility for professional and semi-professional users who need reliable large-hole performance.
Suitable for
Cutting holes for metal pipes and conduit
Creating openings for ventilation ducts and HVAC fittings
Making access holes for electrical boxes and cable routing
General construction tasks requiring precise large-diameter holes in mixed materials
Key specifications
Diameter: 146 mm (5-3/4")
Construction: bi-metal (high-speed cutting teeth bonded to flexible backing)
Intended materials: ferrous and non-ferrous metals, mixed construction materials
Compatibility: designed for use with standard drills and compatible arbors
Application: large-diameter hole cutting for plumbing, electrical, HVAC and general construction
How to use
Secure an appropriate arbor and pilot bit to the drill, then mount the hole saw onto the arbor according to the arbor manufacturer's instructions. Mark the center of the intended hole and clamp the workpiece to prevent movement. Start drilling at low speed to establish the pilot hole, then increase speed and apply steady, even pressure while clearing chips periodically. For metal cutting, use cutting fluid to reduce heat and extend saw life. After cutting, deburr the hole edges as required for the installation.
Usage recommendations
Use moderate feed pressure and appropriate cutting fluid when working in metal to optimize cutting life and prevent overheating. Ensure the drill and arbor are rated for the hole saw size and secure the workpiece to avoid deflection. Replace the hole saw if teeth show significant wear or damage to maintain hole quality and safety.
