## Summary description

Irwin 10504189 is a 60 mm bi-metal hole saw with variable tooth pitch 4.5/5.5 TPI. Intended for cutting round holes in metal, wood and plastics, the bi-metal construction combines HSS cutting edge with a flexible body for durability. Suitable for drill-mounted hole cutting in plumbing, electrical and general workshop tasks.

## Long description

Irwin 10504189 is a 60 mm bi-metal hole saw designed for making round holes in metal, wood and plastics. The bi-metal construction pairs a high-speed steel cutting edge with a flexible alloy body to provide a balance of cutting performance and resistance to breakage. Teeth with a variable pitch of 4.5/5.5 TPI improve chip evacuation and reduce vibration when used with drill-mounted arbors in plumbing, electrical and general workshop tasks.
Advantages
The combination of HSS cutting teeth and a resilient body increases durability and edge life when cutting through mixed materials. Variable tooth pitch helps prevent clogging and promotes smoother cutting across different thicknesses and material types. The 60 mm diameter offers a common size for conduit, pipe and cable entries, while compatibility with standard hole saw arbors ensures straightforward mounting and use with handheld and bench drills.
Suitable for
Cutting round holes in thin to medium-gauge metal sheets
Creating openings in wood for pipes, conduits and fixtures
Drilling through plastics and composite materials for installations
Workshop and site work requiring reliable hole-making with a drill-mounted saw
Key specifications
Material: bi-metal construction with high-speed steel cutting edge and alloy body
Diameter: 60 mm
Tooth pitch: variable 4.5/5.5 TPI for improved cutting and chip removal
Intended use: metal, wood, plastics
Mounting: compatible with standard drill arbors for handheld and bench drills
How to use
Secure the hole saw to a compatible arbor and tighten according to the arbor manufacturer's instructions. Mark the centre of the hole on the workpiece and use a pilot bit or centre punch to prevent walking. Start drilling at low to medium speed, applying steady axial pressure and allowing the saw to cut progressively; increase speed slightly once the teeth have engaged if the material and drill permit. For metal cutting, use cutting fluid to extend tool life and reduce heat. Withdraw periodically to clear chips and inspect the teeth and workpiece.
Usage recommendations
Use appropriate personal protective equipment, clamp workpieces securely, and match drill speed and feed to the material. Replace the hole saw if teeth show significant wear or the saw body is distorted to maintain safe, accurate cutting.
