## Long description

Bi-metal hole saw by M.K. Morse with an 86 mm cutting diameter and 3 mm wall thickness, suitable for use with a 3/8" arbor. Designed for cutting metal and mixed materials where a durable bi-metal tooth set is required. The saw is compatible with portable drills and drill presses and is intended for tasks such as installing pipes, conduits, HVAC components and electrical boxes.
Advantages
The bi-metal construction combines a high-speed steel tooth edge with a flexible alloy body to balance cutting performance and resistance to brittle failure. A 3 mm wall thickness provides stability during cutting and reduces wobble when used with standard drill chucks and a 3/8" arbor. The 86 mm diameter delivers a consistent circular cut for common mechanical and electrical openings while maintaining a compact footprint for handheld drill use and bench-mounted operations.
Suitable for
 Cutting holes in thin to medium-gauge metal sheets and mixed material panels
 Creating openings for plumbing pipes and conduit installations
 Making circular cutouts for HVAC ductwork and registers
 Preparing holes for electrical boxes and switch assemblies
Key specifications
 Cutting diameter: 86 mm
 Wall thickness: 3 mm
 Material: bi-metal (HSS tooth edge bonded to alloy body)
 Arbor interface: designed for 3/8" arbor
 Compatibility: portable drills and drill presses
 Typical use: metal and mixed-material cutting
How to use
Fit the hole saw securely onto a compatible 3/8" arbor and ensure the arbor is tightened correctly in the drill chuck. Mark the center of the desired hole and, if available, pilot-drill a small center hole to guide the pilot bit. Operate the drill at a moderate speed appropriate for the material being cut, applying steady, even pressure. Periodically withdraw the saw to clear chips and allow cooling; use cutting lubricant when working with metals to extend the tool life and improve cut quality. After completing the cut, deburr the edge as necessary.
Usage recommendations
For best results when cutting metal, use a suitable cutting fluid, maintain moderate drill speed to avoid overheating, and let the tool clear chips frequently. Inspect the saw before use for any damage and replace if excessive tooth wear or distortion is present.
