## Summary description

Bi-metal hole saw M.K. Morse Advanced Edge 68 mm (PTA-MK425) is a circular cutting tool designed for drilling large-diameter holes in various materials.

Compatible with standard arbors and used with drills for through-holes.

## Long description

Bi-metal hole saw M.K. Morse Advanced Edge 68 mm is a circular cutting tool engineered for creating precise 68 mm through-holes in a variety of construction and industrial materials. Made from bi-metal, the saw combines a high-speed steel cutting edge with a flexible alloy body to provide improved wear resistance and durability during repetitive drilling. The design is compatible with standard drill arbors and offers stable cutting performance for tasks that require accurate round openings.
Advantages
The bi-metal construction ensures a balance between toughness and cutting hardness, extending the tool life compared with single-material alternatives. The Advanced Edge cutting geometry preserves sharpness and helps maintain consistent hole diameter throughout use. The saw is designed for easy mounting on common drill arbors and provides reliable chip evacuation for cleaner cuts and reduced binding.
Suitable for
Cutting 68 mm holes in thin to medium-thickness metal sheets
Creating openings for pipes and conduits in plumbing and HVAC installations
Electrical panel and enclosure cutouts where precise round holes are required
General maintenance and repair work in workshops and on-site construction
Key specifications
Cutting diameter: 68 mm
Material: bi-metal (high-speed steel teeth bonded to alloy body)
Intended use: drilling through-holes in metal and mixed materials
Compatibility: designed for use with standard drill arbors and hand-held or stand drills
Typical applications: metalworking, plumbing, HVAC, electrical installations
How to use
Secure the hole saw to a compatible arbor and fasten the arbor into the drill chuck. Mark the center point of the intended hole and, if available, start with a pilot drill or pilot bit to reduce wandering. Position the saw perpendicular to the work surface and apply steady, moderate pressure while drilling at an appropriate speed for the material being cut. Use cutting lubricant when drilling metal to reduce heat and extend tool life. After completing the cut, retract the saw and clear chips before removing the workpiece.
Usage recommendations
For best results, select drill speeds and feed rates suitable for the material thickness, use cutting fluid when working with metals, and ensure the arbor and drill are securely tightened to minimize runout. Inspect the teeth regularly for wear and replace the saw if cutting performance declines significantly.
