## Long description

Irwin 10504194 is a 70 mm bi-metal hole saw with a variable tooth pitch of 4.5/5.5 TPI, created for cutting clean circular holes in metal and a range of other materials. The bi-metal construction combines a high-speed steel cutting edge with a flexible alloy body to provide improved durability and heat resistance during intermittent and continuous drilling. The saw is intended for tradespeople and workshop environments where reliable hole cutting and extended tool life are required.
Advantages
The bi-metal design increases resistance to wear and reduces the risk of tooth breakage, while the variable tooth pitch helps reduce vibration and produce smoother cuts across different material thicknesses. The 70 mm diameter allows for larger openings without the need for multiple passes, and the construction supports work in steel, stainless steel and non-ferrous metals as well as many common construction materials. The saw's design balances cutting speed and durability to deliver consistent hole quality and longer service life compared with standard carbon-steel saws.
Suitable for
Cutting circular holes in mild and stainless steel sheets
Creating openings in non-ferrous metals such as aluminium and copper
Installation tasks in plumbing, HVAC and electrical work that require 70 mm holes
Workshop and on-site fabrication where durable hole-making tools are needed
Key specifications
Diameter: 70 mm
Material: bi-metal (HSS cutting edge bonded to alloy body)
Tooth pitch: variable 4.5/5.5 TPI
Suitable for: steel, stainless steel, non-ferrous metals and similar materials
Typical mounting: compatible with standard hole saw arbors and mandrels
How to use
Select a compatible arbor and secure the hole saw to the drill according to the arbor manufacturer's instructions. Mark the center point of the required hole and, if available, use a pilot drill or a pilot arbor to locate the cut. Start drilling at low speed to establish the cut, applying steady pressure and allowing the saw to cut without forcing. For metal cutting, use appropriate cutting fluid or coolant to reduce heat build-up and prolong blade life. Withdraw the saw periodically to clear chips and allow cooling when cutting thicker materials.
Usage recommendations
Use an appropriate arbor with a secure pilot to maintain concentric cutting. Apply cutting fluid when working with stainless steel or other tough alloys. Do not exceed recommended drill speeds for the material being cut, and wear proper eye and hand protection during operation.
