## Summary description

Irwin 10504187 bi-metal hole saw, 57 mm diameter, with vario tooth configuration 4.5/5.5 TPI.

## Long description

The Irwin 10504187 Bi-Metal hole saw, 57 mm diameter, features a variable tooth pitch of 4.5/5.5 TPI designed to cut clean round openings in metal, wood and plastic. Its bi-metal construction combines a high-speed steel cutting edge with a flexible steel body to deliver durability, improved heat resistance and longer life compared with standard carbon-steel hole saws. The 57 mm cutting diameter and Vario Tooth geometry balance fast cutting with reduced burr formation for installers and tradespeople working on pipe, conduit and cable penetrations.
Advantages
The combination of bi-metal construction and Vario Tooth profile provides extended tool life and consistent cutting performance across mixed materials. The 4.5/5.5 TPI tooth spacing offers a compromise between a coarse tooth for rapid material removal and a finer tooth for smoother edges, reducing the need for secondary finishing. The saw’s design resists heat build-up during prolonged use and maintains cutting efficiency on thin steel panels as well as on wood and plastics.
Suitable for
 Cutting circular openings for pipes and conduits in metal sheets
 Creating cable access holes in walls and panels
 Drilling openings in wood for fittings and fixtures
 Cutting through plastic and composite panels
Key specifications
 Cutting diameter: 57 mm
 Tooth configuration: Vario Tooth, 4.5/5.5 TPI
 Material: bi-metal (high-speed steel teeth bonded to flexible steel body)
 Suitable materials: ferrous metal sheets, wood, plastics
 Intended use: hand-held drills and drill presses with compatible arbor
How to use
Mark the center point of the desired hole and, if available, use a pilot drill or the hole saw’s pilot bit to establish accurate positioning. Fit the hole saw to a compatible arbor and secure it tightly. Operate the drill at a speed appropriate for the work material — lower speeds for metals and higher speeds for wood and plastics — while applying steady, moderate pressure. Periodically withdraw the saw to clear chips and allow cooling, especially when cutting metal. After cutting, deburr the edge as required for a clean finish.
Usage recommendations
Use proper personal protective equipment, including eye protection and gloves. For metal applications, use cutting lubricant to reduce heat and extend the cutting life. Ensure the arbor and pilot bit are correctly fitted to prevent wobble and achieve a clean, accurate hole.
