Irwin Blades 88604IBB92970 Bandsaw Blade 8-12 Tpi Bi-metal

Product Description

The IRWIN BLADES 88604IBB92970 is a welded bi-metal bandsaw blade designed for contour and straight cutting applications on metal and other tough materials. Measuring 9 feet 9 inches in length and 0.5 inches wide, this blade features a variable pitch tooth pattern ranging from 8 to 12 TPI, which helps reduce vibration and harmonics during cutting. The teeth are made from M42 high speed steel, a cobalt-enhanced grade known for heat resistance and edge retention. At 0.025 inches thick, the blade is sized for standard bandsaw wheel clearances. This blade is intended for installation and use by machinists, maintenance technicians, and metalworking professionals.

This blade is suited for use in industrial and commercial metalworking environments where a pre-welded, ready-to-install replacement blade is needed. The variable pitch design from 8 to 12 TPI makes it effective across a range of material thicknesses and cross-sections, reducing the need to swap blades between jobs. It is a direct drop-in for bandsaws with compatible wheel dimensions and blade guides accepting a 0.5-inch-wide, 0.025-inch-thick blade. Typical applications include cutting bar stock, tubing, structural shapes, and solid sections in fabrication and maintenance settings.

Key Features

• Variable pitch 8 to 12 TPI tooth pattern reduces vibration and improves chip evacuation
• M42 high speed steel teeth provide enhanced heat and wear resistance for metal cutting
• Bi-metal construction combines a flexible alloy steel back with hardened HSS tooth tips
• Pre-welded blade ships ready to install with no field welding required
• Straight tooth form suits general-purpose contour and cross-cut bandsaw work
• 0.025-inch blade thickness compatible with standard bandsaw guide clearances

Compatibility

Designed as an OEM-style replacement bandsaw blade for vertical or horizontal bandsaws that accept a 9-foot 9-inch loop, 0.5-inch-wide, 0.025-inch-thick blade with standard bi-metal specifications.

Installation Notes

Bandsaw blade replacement should be performed by a qualified technician following the machine manufacturer's lockout/tagout procedure before opening the blade guards. Verify wheel diameter, blade width capacity, and guide bearing clearances match the blade dimensions before installation. Tension the blade per the machine manufacturer's specification using the built-in tension gauge; do not estimate tension by hand deflection alone. Wear cut-resistant gloves when handling the coiled or uncoiled blade.
