## Long description

Irwin 10504198 Bi-Metal hole saw, 83 mm diameter, is engineered for cutting clean circular openings in metal and mixed materials. Constructed from bi-metal steel and featuring vario tooth geometry with 4.5/5.5 TPI, this hole saw balances aggressive material removal with chip evacuation to maintain cutting speed and extend tool life. It fits standard arbors and can be used with hand drills and drill presses for plumbing, HVAC, electrical installations and general metalworking tasks.
Advantages
The vario tooth arrangement (4.5/5.5 TPI) provides a combination of fast cutting and longer wear life compared with uniform-tooth designs. Bi-metal construction delivers toughness and resistance to breakage while remaining sufficiently flexible for repetitive use. Compatibility with standard arbors allows quick mounting and interchangeability between cordless and corded drills or drill presses. The 83 mm diameter is suitable for creating openings for pipes, conduits and fixtures while preserving edge quality for minimal rework.
Suitable for
 Cutting holes in thin to medium-gauge steel and sheet metal
 Creating openings for plumbing pipes and fittings
 Making electrical conduit and cable access holes
 General metalworking and installation tasks in HVAC applications
Key specifications
 Material: bi-metal construction for durability and toughness
 Diameter: 83 mm cutting capacity
 Tooth geometry: vario tooth 4.5/5.5 TPI for combined speed and durability
 Mounting: designed to fit standard hole saw arbors for drills and presses
 Intended materials: metal and mixed-material applications including sheet metal
How to use
Secure the hole saw to a compatible arbor and tighten according to the arbor manufacturer's instructions. Mark the center of the required cut and, if possible, pilot-drill a center hole to guide the arbor. Use a drill or drill press at appropriate speed for the material being cut, applying steady pressure and allowing the teeth to remove material without forcing. For metal cutting, use cutting fluid or coolant to reduce heat and extend blade life, and clear chips periodically to maintain cutting efficiency. After cutting, deburr the hole edges as needed.
Использование и уход
For consistent results, match drill speed and feed to the metal thickness, use appropriate coolant for prolonged cutting sessions, and replace the hole saw if excessive wear or tooth damage is visible.
