## Summary description

Irwin 10504190 is a 64 mm bi-metal hole saw with Weldtec construction and a variable tooth pitch of 4.5/5.5 TPI. Designed for cutting through metal and other materials, this hole saw combines durability of bi-metal with a tooth geometry aimed at efficient cutting and chip evacuation. Suitable for installers and tradespeople for creating circular holes in sheet metal, pipes and structural components.

## Long description

Irwin 10504190 is a 64 mm bi-metal hole saw with Weldtec construction and a variable tooth pitch of 4.5/5.5 TPI. It is engineered to cut circular holes in thin and medium-thickness metal, as well as in other construction materials where a durable cutting edge and efficient chip evacuation are required. The bi-metal composition provides a balance of toughness and wear resistance while the Weldtec joint enhances blade retention and service life.
Advantages
The combination of bi-metal teeth and Weldtec construction ensures long life under intermittent and continuous use. Variable tooth pitch (4.5/5.5 TPI) reduces vibration and improves chip clearance for smoother cutting through metal sheets, pipes and profiles. The 64 mm diameter offers a common size for installation tasks, and the hardened cutting edge maintains cutting performance over repeated cycles.
Suitable for
 Creating circular openings in sheet metal for conduits, fittings and junction boxes
 Cutting holes in steel and non-ferrous metal pipes and tubes
 Installing HVAC components and electrical fixtures that require precise round holes
Key specifications
 Diameter: 64 mm
 Tooth type: Bi-metal teeth
 Tooth pitch: Variable 4.5/5.5 TPI for improved chip evacuation
 Construction: Weldtec joint between crown and mandrel for increased strength
 Material suitability: Designed for metal and similar construction materials
How to use
Install the hole saw on a compatible arbor and secure it to the drill according to the arbor manufacturer's instructions. Mark the center point of the hole and, if available, use a pilot drill or center punch to prevent wandering. Start drilling at low speed to establish the cut, then apply steady pressure and moderate speed appropriate for the workpiece material. Use cutting fluid when working with steel to reduce heat and extend tool life. Clear chips periodically to maintain cutting efficiency.
Usage recommendations
Use a drill with sufficient torque and a compatible arbor rated for bi-metal hole saws. For prolonged performance, avoid overheating by using cutting lubricant and intermittent cutting cycles when working with hard metals. Inspect the hole saw before use for signs of wear or damage and replace if teeth are severely worn or the Weldtec joint is compromised.
