Irwin IR373218BX Bi-metal Hole Saw 2-1/8 Inches

Product Description

The IRWIN IR373218BX is a bi-metal hole saw sized at 2-1/8 inches, designed for cutting clean, accurate holes in a range of materials encountered in trade work. Bi-metal construction combines a high-speed steel cutting edge with a flexible alloy steel body, delivering durability under repeated use and resistance to tooth breakout. This saw is a standard tool for electricians, plumbers, and HVAC technicians who need consistent, repeatable hole cuts during installation and rough-in work. The 2-1/8 inch diameter makes it well suited for common trade applications including conduit knockouts, pipe penetrations, and fixture openings.

This hole saw fits typical residential and light commercial installation scenarios where a 2-1/8 inch cut is required. Electricians use this size for conduit and box work, while plumbers and HVAC techs reach for it during rough-in and equipment mounting tasks. It is sold individually and is compatible with standard arbor systems used across major hole saw brands.
