## Summary description

Irwin 10504195 is a 73 mm bi-metal hole saw with a variable tooth pitch of 4.5/5.5 TPI designed for cutting holes in metal and mixed materials. The bi-metal construction combines tool steel cutting edges with a flexible backing for improved durability and resistance to heat. Suitable for installers and tradespeople for accurate circular cuts in sheet metal, pipes and structural components.

## Long description

Irwin 10504195 is a 73 mm bi-metal hole saw engineered for cutting clean circular openings in metal and mixed construction materials. The saw combines high-speed tool steel cutting edges with a flexible backing, offering improved durability and heat resistance compared with standard stamped teeth. Its 4.5/5.5 TPI variable tooth pitch balances fast material removal with reduced vibration and smoother cutting performance.
Advantages
The bi-metal construction delivers a longer service life when cutting stainless steel, mild steel, sheet metal and some non-ferrous materials. Variable tooth pitch minimizes chatter and helps evacuate chips more efficiently, reducing clogging and heat build-up. The 73 mm diameter provides a common hole size for pipe penetrations, conduit entry and larger cable access, while compatibility with standard arbor shanks makes it suitable for most drill setups.
Suitable for
Cutting holes in sheet metal and steel panels
Creating openings for pipes, conduits and ventilation
On-site installations by electricians, plumbers and HVAC technicians
Workshop fabrication where circular holes up to 73 mm are required
Key specifications
Cutting diameter: 73 mm
Material: bi-metal (high-speed steel teeth bonded to flexible backing)
Tooth pitch: variable 4.5/5.5 TPI for mixed-material cutting
Recommended use: metal and mixed materials including sheet metal and pipes
Design: toothed cup for circular hole cutting with chip evacuation
How to use
Mount the hole saw on a compatible arbor and secure it to a drill with sufficient power and speed control. Mark the centre of the required hole and use a pilot bit to start the cut where applicable. Apply steady, moderate pressure and maintain consistent speed; allow the teeth to remove material without forcing the tool. Periodically withdraw the saw to clear chips and cool the cutting edge. Use cutting fluid when working with stainless or thicker steels to reduce heat and extend tool life.
Usage recommendations
For best results, use variable speeds appropriate to the material: lower speeds for stainless steel and higher speeds for thin sheet metal. Keep the tool aligned and avoid side loads to preserve the saw geometry and prolong life.
