Irwin Blades 87946IBB144420 Bandsaw Blade 14.5 Ft Bi-metal

Product Description

The IRWIN BLADES 87946IBB144420 is a welded bi-metal bandsaw blade designed for contour and straight cutting on metal-cutting band saw machines. Measuring 174 inches long and 1 inch wide with a 0.035-inch thickness, this blade uses a variable pitch of 3 to 4 TPI to reduce vibration and harmonics during the cut. The bi-metal construction pairs a flexible alloy steel backer with M42 high speed steel teeth, delivering both fatigue resistance and edge retention. It is suited for production shops, fabrication operations, and maintenance facilities where consistent metal cutting performance is required.

This blade is intended for use on metal-cutting band saws with a wheel-to-wheel capacity that accommodates a 174-inch blade length. The variable 3 to 4 TPI pitch pattern handles a range of cross-sections, making it effective on solid bar stock, structural shapes, and tubing. The positive tooth rake angle promotes aggressive chip removal, which reduces heat buildup and extends blade life. Licensed tradespeople and industrial maintenance mechanics are the primary installers of this blade type.

Key Features

• Bi-metal construction with M42 high speed steel teeth for extended edge life on ferrous and non-ferrous metals
• Variable pitch of 3 to 4 TPI reduces vibration and noise during cutting
• Positive tooth rake angle promotes aggressive chip evacuation
• 0.035-inch blade thickness provides flexibility and resistance to fatigue cracking on band saw wheels
• Toothed cutting edge style suited for solid stock, structural profiles, and tubing
• Factory-welded joint for consistent blade tracking and reliable performance from first use

Compatibility

Designed as an OEM-style replacement or upgrade blade for metal-cutting band saws that accept a 174-inch blade length, 1-inch blade width, and 0.035-inch blade thickness.

Installation Notes

Band saw blade installation and tensioning should be performed by qualified technicians familiar with the specific saw model being serviced. Disconnect and lock out electrical power to the band saw before removing or installing any blade. Use appropriate blade-handling gloves, as the toothed edge presents a laceration hazard during handling. Always verify blade tension, tracking alignment, and blade guide settings before returning the machine to service.
