## Summary description

Bimetal hole saw Irwin 40 mm (model 10504178) — cutting tool designed for creating 40 mm diameter holes in metal, wood and plastic. Made from bimetal for improved durability and heat resistance, suitable for use with drills and drill drivers. Ideal for plumbing, electrical installations and general workshop tasks requiring precise circular cuts.

## Long description

The Irwin bimetal hole saw 40 mm is a cutting tool designed to create clean circular holes with a 40 mm diameter in metal, wood and plastic. Constructed from bimetal materials, this hole saw provides enhanced durability and heat resistance for use with standard drills and drill drivers. The tool is suitable for a range of installation and workshop tasks that require accurate round openings, including plumbing and electrical work.
Advantages
The bimetal construction combines high-speed steel teeth with a flexible backing, improving resistance to wear and thermal stress during prolonged cutting. Teeth geometry delivers efficient material removal and reduces jamming, while the 40 mm diameter offers a common size for pipe and conduit entries. The hole saw is compatible with common arbor systems and can be used in portable drills, providing a balance of cutting performance and service life for general-purpose applications.
Suitable for
Cutting 40 mm holes for pipes and conduits in plumbing and HVAC work
Creating openings for cable glands and electrical boxes
Drilling holes in sheet metal, wood panels and plastic parts
Workshop tasks requiring repeatable, circular cuts with a hand drill
Key specifications
Cutting diameter: 40 mm
Material: bimetal (high-speed steel teeth with flexible backing)
Compatible with standard drill and drill driver arbors
Suitable for metal, wood and plastic
Designed for manual and portable power drills
How to use
Install the hole saw on a compatible arbor or mandrel and secure it in the drill chuck. Mark the center of the desired hole and, if available, pilot-drill a guide hole. Position the pilot bit or arbor tip on the mark, start the drill at low speed to establish the cut, then increase speed and apply steady, even pressure. Use moderate feed to avoid overheating; periodically withdraw the saw to clear chips and allow cooling. After cutting, deburr the hole edges as needed.
Usage recommendations
For best results when cutting metal, use cutting lubricant or coolant to extend blade life and reduce heat. Select appropriate drill speed for the material: lower speeds for metals and higher speeds for wood and plastics. Wear eye protection and follow standard safety practices when operating power tools.
