Irwin IR373034BX Bi-metal Hole Saw 3/4 Inch

Product Description

The IRWIN IR373034BX is a bi-metal hole saw sized at 3/4 inch, designed for cutting clean, accurate holes in a wide range of materials encountered in trade work. Bi-metal construction combines a high-speed steel cutting edge with a flexible alloy steel body, allowing the saw to handle both wood and metal substrates without shattering or premature tooth wear. This hole saw is a hand tool used by electricians, plumbers, HVAC technicians, and general contractors when running pipe, conduit, or wire through framing and panels. Its compact 3/4-inch diameter makes it suited for smaller penetrations where precision matters.

This hole saw is applicable in residential and light commercial installation work. Common uses include drilling through studs, sheet metal, drywall, and plastic for conduit runs, small pipe penetrations, and cable pass-throughs. The 3/4-inch size aligns with standard trade penetration requirements for low-voltage wiring, small-diameter conduit, and copper or PEX tubing rough-in work. It is sold individually, making it a practical add-on or replacement for a worn saw of the same diameter.

Key Features

• Bi-metal construction for durability across wood, metal, and plastic substrates
• 3/4-inch cutting diameter for standard trade penetration applications
• High-speed steel teeth for extended cutting life
• Sold individually for single-size replacement or supplemental use

Compatibility

Designed as a standard bi-metal hole saw replacement compatible with arbors that accept 3/4-inch hole saws following common industry mounting standards.

Installation Notes

Installation of this hole saw requires a compatible arbor and a drill capable of maintaining controlled, consistent speed through the material being cut. Electricians and plumbers should verify that any penetrations through fire-rated assemblies are properly firestopped per applicable local codes. Keep the cutting surface clear of debris and allow the saw to cool between cuts when working through metal to preserve tooth life.
