Starrett 20725 Welded Bandsaw Blade 2-3 Tpi Bi-metal

Product Description

The STARRETT 20725 is a welded bi-metal bandsaw blade engineered for professional metal-cutting applications. Part of the Intenss PRO series, it measures 138 inches (11 feet 6 inches) in length, 1-1/4 inches in width, and 0.042 inches in thickness. The blade features high speed steel teeth set in a raker configuration with a variable pitch pattern of 2-3 TPI, which helps reduce vibration and harmonic resonance during cuts. A positive rake angle improves chip clearance and cutting efficiency through both ferrous and non-ferrous stock. The flexible back construction extends blade fatigue life on continuous cutting operations. Fabricators, maintenance machinists, and metal shop technicians are the primary installers of this blade.

This blade is suited for production and maintenance cutting environments where ferrous and non-ferrous metals are processed on vertical or horizontal band saws with a 138-inch blade capacity. Variable pitch tooth geometry makes it effective across a range of cross-sections, from solid bar stock to structural shapes and tubing. The 1-1/4-inch width provides lateral rigidity for straight cuts in heavier sections. It is designed for professional shop use where consistent, repeatable cuts are required across high-volume work.

Key Features

• Bi-metal construction with high speed steel teeth for extended cutting life
• Variable pitch 2-3 TPI pattern reduces vibration and improves cut finish
• Positive rake angle promotes aggressive chip evacuation in metal stock
• Raker tooth set delivers consistent kerf geometry across ferrous and non-ferrous materials
• Flexible back design resists fatigue cracking under continuous band saw operation
• Welded construction provides a seamless joint for smooth, uninterrupted blade tracking

Compatibility

Designed as an OEM-style replacement or direct-fit blade for band saws requiring a 138-inch (11 feet 6 inches) blade length with a 1-1/4-inch width capacity. Compatible with ferrous metal and non-ferrous metal cutting applications as specified by the manufacturer.

Installation Notes

Blade installation should be performed by a qualified machinist or fabricator with the band saw fully powered down and isolated from its power source. Confirm wheel diameter, blade guides, and blade tension settings match the 1-1/4-inch width and 0.042-inch thickness of this blade before mounting. Wear cut-resistant gloves when handling the coiled blade during installation. Follow the saw manufacturer's tensioning and tracking procedures before running the blade under load.
