Irwin 373200BX Bi-metal Hole Saw 2 Inches

Product Description

The IRWIN 373200BX is a bi-metal hole saw with a 2-inch cutting diameter, designed for trade professionals who need reliable performance across a range of materials. The bi-metal construction combines a high-speed steel cutting edge with a flexible alloy steel body, allowing it to cut through wood, aluminum, copper, iron, stainless steel, and zinc without tool changes. Rated at 170 RPM, it is suited for controlled, clean-cut applications where material integrity matters. Electricians, plumbers, and HVAC techs reach for this saw when punching holes through panels, enclosures, and structural members during rough-in work.

The 373200BX is used in both residential and light commercial applications. It fits standard hole saw mandrels and is a common choice for running conduit, pipe, and ductwork penetrations through framing, sheet metal, and similar substrates. Its 2-inch diameter is a frequently used size in trade rough-in scenarios where consistent bore size is required across multiple penetrations.

Key Features

• Bi-metal construction for cutting wood, aluminum, copper, iron, stainless steel, and zinc
• 2-inch cutting diameter for standard trade rough-in penetrations
• 170 RPM operating speed for controlled material removal
• Compatible with standard hole saw mandrel arbors
• Sold individually (each)

Compatibility

Designed as an OEM-style replacement and standard fit for use with common hole saw mandrel arbors used in electrical, plumbing, and HVAC rough-in applications.

Installation Notes

Install the hole saw onto a compatible mandrel arbor before use and confirm the arbor locking mechanism is fully engaged. Set drill speed to the rated 170 RPM or as close as the drill allows — higher speeds can overheat the bi-metal teeth and shorten blade life. Always secure the workpiece before cutting and use appropriate PPE including eye protection. Power down and unplug the drill before changing or inspecting the saw blade.
