## Summary description

Irwin 10504196 is a 76 mm bi-metal hole saw designed for cutting clean circular openings in metal and other materials. It features a variable tooth pitch of 4.5/5.5 TPI for efficient cutting and reduced vibration. Suitable for use with drills and drill presses, this hole saw is intended for plumbing, electrical installations and general metalworking where durable, precise hole cutting is required.

## Long description

The Irwin 10504196 bi-metal hole saw, 76 mm diameter, is designed for creating clean circular openings in metal and other compatible materials. Engineered with a variable tooth pitch of 4.5/5.5 TPI, this hole saw balances fast material removal with controlled cutting to reduce vibration and improve hole quality. It is compatible with standard drill chucks and drill presses when used with the appropriate arbor and pilot bit, and is intended for trades and workshops that require accurate through-holes in thin to medium-thickness sheet metal and similar substrates.
Advantages
The bi-metal construction combines a high-speed steel cutting edge with a flexible alloy backing for extended life and resistance to tooth breakage. Variable tooth pitch improves chip clearance and reduces chatter for smoother cutting and longer tool life. The 76 mm diameter provides a common size for pipe penetrations and fixture mounting, while compatibility with standard drill equipment makes the saw versatile for on-site and workshop use.
Suitable for
Drilling circular openings in steel sheet, stainless steel and non-ferrous metal sheets
Creating holes for plumbing pipes and conduits
Electrical installations and mounting junction boxes
General metalworking and HVAC ductwork penetrations
Key specifications
Cutting diameter: 76 mm
Material: bi-metal construction (HSS teeth with alloy backing)
Tooth pitch: variable 4.5/5.5 TPI for optimized cutting and chip evacuation
Suitable application thickness: thin to medium sheet metals and similar materials
Compatible with drills and drill presses using appropriate arbor and pilot bit
How to use
Secure the appropriate arbor and pilot bit in the drill, fit the hole saw onto the arbor, and tighten according to the arbor manufacturer's instructions. Mark the centre point of the intended hole on the workpiece and clamp the workpiece firmly to prevent movement. Start drilling at low speed to establish the pilot hole, then increase speed as appropriate for the material while applying steady axial pressure. Use cutting fluid when working with steel or stainless steel to reduce heat and prolong tool life. After cutting, remove the slug and deburr the hole as needed.
Usage recommendations
For best results, use the hole saw with a suitable arbor and pilot bit, maintain consistent feed pressure, and apply cutting fluid when cutting ferrous metals. Inspect teeth for wear before use and replace the saw when cutting becomes slow or the quality of holes degrades.
