Irwin IR2084200 Bi-metal Utility Knife Blades 20 Pack

Product Description

The IRWIN IR2084200 is a bi-metal utility knife blade sold in a 20-pack, designed for tradespeople who demand consistent cutting performance across a range of materials. Bi-metal construction bonds a high-speed steel cutting edge to a flexible alloy steel body, allowing the blade to hold an edge longer than standard carbon steel blades while resisting breakage under lateral stress. These blades fit standard utility knives commonly used in electrical, HVAC, plumbing, roofing, and general construction work. The 20-count pack reduces job-site downtime by keeping replacements on hand throughout the workday.

These blades are suited for cutting insulation, roofing felt, housewrap, drywall tape, rubber gaskets, plastic sheathing, and similar trade materials. The bi-metal design makes them particularly well-suited for applications where the blade encounters both soft and semi-hard materials in the same cut. Electricians, HVAC technicians, plumbers, and general contractors will find the pack size practical for ongoing service work or new construction projects where frequent blade changes are standard practice.

Key Features

• Bi-metal construction for extended edge retention compared to standard carbon steel blades
• Flexible alloy steel body resists snapping under lateral load

Installation Notes

Blade replacement should be performed by a qualified tradesperson following the knife manufacturer's blade-change procedure. Retract or remove the existing blade fully before installing a new one. Use appropriate cut-resistant gloves when handling exposed blades. Dispose of used blades in a designated sharps or blade disposal container in accordance with applicable jobsite safety protocols.
