Bi-metal hole saw Irwin, model 10504165, with a 20 mm cutting diameter. Designed for cutting round holes in metal, wood and some plastics where a bi-metal construction provides durability and cutting performance.

## Long description

Irwin bi-metal hole saw with a 20 mm cutting diameter is designed for making clean circular openings in a variety of materials including metal, wood and some plastics. Compatible with standard drill drivers and hole saw arbors, this 20 mm hole saw gives a combination of cutting performance and durability thanks to its bi-metal construction, which joins high-speed steel cutting edges to a flexible backing metal for longer life under repetitive use.
Advantages
The bi-metal design balances toughness and sharpness to resist tooth wear and reduce breakage during intensive cutting. A 20 mm cutting diameter offers precision for small-diameter penetrations while the saw’s tooth geometry facilitates efficient chip evacuation and reduced heat build-up. The hole saw is compatible with common drill drivers and arbors, enabling straightforward fitting and predictable cutting behavior across different materials.
Suitable for
Cutting round openings for plumbing fittings and pipe penetrations
Creating holes for electrical conduit and cable glands
Making pass-throughs for installation hardware and fasteners
Drilling small-diameter holes in metal sheets, timber and plastic panels
Key specifications
Cutting diameter: 20 mm
Construction: bi-metal (high-speed steel teeth bonded to flexible backing)
Material compatibility: metal, wood, some plastics
Intended drive: compatible with standard drill drivers and hole saw arbors
Typical applications: plumbing, electrical, installation tasks requiring circular openings
How to use
Fit the hole saw to an appropriate arbor and secure it in a drill driver according to the arbor manufacturer’s instructions. Mark the center of the required hole and, if available, use a pilot bit to guide initial positioning. Begin drilling at low speed to establish the cut, then increase speed and apply steady, moderate pressure to allow efficient cutting while minimising heat and vibration. Clear chips periodically and allow the tool to cool if cutting dense metal. After finishing the cut, remove the slug from the hole saw with care to avoid damaging the teeth.
Usage recommendations
Use cutting lubricant when sawing through metal to extend tool life and improve cut quality. Wear appropriate personal protective equipment—safety glasses, gloves and hearing protection—and secure the workpiece before drilling to ensure accuracy and safety.
