Irwin IR373058BX Bi-metal Hole Saw 5/8 Inches

Product Description

The IRWIN IR373058BX is a bi-metal hole saw with a 5/8-inch cutting diameter, designed for boring clean, precise holes through wood, plastic, drywall, and thin metal. Bi-metal construction combines a high-speed steel cutting edge with a flexible steel body, giving the saw blade durability and resistance to breakage under torque. This saw is sized for small-diameter penetrations and is commonly used by electricians, plumbers, and HVAC technicians when running conduit, pipe, or low-voltage wiring through framing and panels. The compact 5/8-inch size makes it a go-to for tight clearance work.

This hole saw is suited for residential and light commercial applications where small, accurate penetrations are required. Typical uses include drilling through studs, plates, and light-gauge sheet material for wire and tubing runs. It is sold individually and sized for standard arbor-compatible drill setups.

Key Features

• Bi-metal construction for extended cutting life versus carbon steel alternatives
• 5/8-inch cutting diameter for small-clearance penetrations
• Compatible with standard hole saw arbors
• Suitable for wood, plastic, drywall, and thin metal substrates
• Sold as a single unit (UOM: Each)

Compatibility

Designed as an OEM-style replacement and standard-use hole saw for trade applications requiring a 5/8-inch bi-metal cutting tool compatible with standard hole saw arbor systems.

Installation Notes

Install the hole saw onto a compatible arbor before use and verify the mandrel is securely threaded before operating. Electricians, plumbers, and HVAC technicians should confirm material type and wall thickness before selecting feed rate and drill speed. Always wear eye protection and secure the workpiece to prevent rotation during drilling. Follow applicable NEC, IPC, or IFGC clearance and penetration requirements when drilling through structural or fire-rated assemblies.
