Product information

Description

The M.K. Morse Advanced Bi-Metal hole saw, 79 mm (3-1/8"), is a circular cutting tool designed for creating round openings in metal and mixed materials. Constructed with bi-metal teeth, this hole saw combines a high-speed steel cutting edge bonded to a flexible alloy body to balance cutting performance and durability. It is intended for use with hand drills and drill presses in trade applications such as plumbing, HVAC, electrical and general metalworking where precise, long-life hole cutting is required.

Advantages

The bi-metal construction provides improved wear resistance and extended edge life compared with conventional carbon steel hole saws. The saw design supports efficient chip evacuation and sustained cutting performance across a range of ferrous and non-ferrous metals, as well as laminated or thin-sheet materials. Compatibility with standard arbor systems and common drill equipment allows easy integration into existing toolsets.

Suitable for

  • Cutting circular holes in sheet metal for conduit, pipe and duct penetrations
  • Create openings for electrical boxes, switchgear and control enclosures
  • Making holes in HVAC components and brackets
  • General metal fabrication and maintenance tasks requiring durable hole cutting

Key specifications

  • Diameter: 79 mm (3-1/8")
  • Material: bi-metal teeth (high-speed steel cutting edge bonded to alloy body)
  • Cutting capability: ferrous and non-ferrous metals, laminated materials and thin sheet
  • Mounting: compatible with standard hole saw arbors for drills and drill presses
  • Application: manual and machine drilling in trade and workshop environments

How to use

Secure the appropriate arbor in the drill or drill press, mount the hole saw onto the arbor and ensure the pilot bit is fitted if required. Mark the centre of the intended hole, position the pilot bit, and start drilling at low speed to establish the cut. Increase speed and maintain steady feed pressure, allowing the saw teeth to clear chips and avoid overheating. For thicker or harder metals use cutting lubricant and intermittent drilling to prolong blade life. After cutting, remove burrs and check the hole for correct dimensions before installation.

Usage recommendations

For optimal performance, use appropriate cutting fluid when working with stainless steel or other hard alloys, ensure correct arbor fitment and maintain moderate drilling speeds. Replace the hole saw if teeth are visibly worn, damaged or if cutting performance declines.
