Irwin Blades 87782IBB123660 Welded Bandsaw Blade

Product Description

The IRWIN BLADES 87782IBB123660 is a welded bi-metal bandsaw blade designed for contour and straight cutting applications on metal-cutting bandsaws. The blade measures 12 feet in length and 1 inch in width, with a 0.035-inch thickness and a variable pitch of 3 to 4 teeth per inch (TPI). The bi-metal construction pairs a flexible alloy steel backer with M42 high speed steel teeth, giving the blade resistance to tooth strippage under interrupted cuts and extended cutting life compared to carbon-steel alternatives. Licensed HVAC sheet metal shops, plumbing fabricators, pipefitters, and general metalworking professionals are the primary users of this blade type.

This blade is suited for horizontal and vertical metal-cutting bandsaw machines that accept a 12-foot blade loop. The variable 3 to 4 TPI pitch pattern reduces harmonic vibration during the cut, which improves surface finish and reduces noise on structural steel, pipe, tubing, and solid bar stock. The positive rake angle on each tooth drives material removal efficiently, making the blade a practical choice for production cutting environments as well as job-site fabrication shops working with ferrous and non-ferrous metals.

Key Features

• Bi-metal construction with M42 high speed steel teeth for extended tooth life
• Variable pitch of 3 to 4 TPI reduces vibration and improves cut quality on metal stock
• Positive tooth rake angle promotes aggressive, efficient material removal
• 0.035-inch blade thickness balances flexibility and tracking stability on standard bandsaw wheels
• Welded loop construction ready to install without field joining
• 1-inch blade width supports straight cuts and mild contour work on metal-cutting bandsaws

Compatibility

Designed as an OEM-style replacement or upgrade blade for metal-cutting bandsaw machines that accept a 12-foot by 1-inch blade loop with 0.035-inch thickness.

Installation Notes

Blade installation should be performed by a qualified technician familiar with bandsaw equipment. Disconnect and lock out electrical power to the bandsaw before removing the old blade or installing a new one. Verify wheel diameter, blade guides, and tension settings on the machine match the 1-inch width and 0.035-inch thickness specification before tensioning. Handle the coiled blade with cut-resistant gloves, as the toothed edge presents a laceration hazard during uncoiling and threading.
