Starrett 15397 Welded Bandsaw Blade 10-14 Tpi Bi-metal

Product Description

The STARRETT 15397 is a welded bi-metal bandsaw blade designed for demanding metal-cutting applications in production and fabrication environments. Measuring 89 inches in total length and 0.5 inches wide, this blade runs on horizontal and vertical metal-cutting bandsaws common in machine shops and industrial maintenance settings. The blade is manufactured to M42 high-speed steel tooth specification with a positive rake angle and raker tooth set, making it well suited for cutting ferrous and non-ferrous materials at controlled feed rates. At 0.035 inches thick with a flexible back, it is built to handle the continuous flex of bandsaw operation without premature fatigue. Licensed metalworking professionals and industrial maintenance technicians are the primary installers.

This blade is part of the Starrett Intenss PRO-DIE series, targeting precision die, tool, and general metal-cutting work. The variable 10 to 14 TPI pitch pattern reduces harmonic vibration during cutting, which is especially beneficial when transitioning through varying cross-sections. Rated for steel, stainless steel, exotic steel, and non-ferrous metals, it covers a broad range of shop materials in a single blade specification. It is appropriate for both production runs and intermittent job-shop use where a single versatile blade is preferred over application-specific tooling.

Key Features

• M42 high-speed steel teeth for extended cutting life in hard and exotic metals
• Variable 10-14 TPI pitch reduces vibration and improves surface finish across varying material cross-sections
• Raker tooth set with positive rake angle for aggressive, efficient chip clearance
• Flexible back construction resists fatigue cracking under continuous bandsaw operation
• Contour cutting capable, supporting radius cuts in addition to straight profiles
• Welded construction provides a consistent, reliable joint at blade length specification

Compatibility

Designed as an OEM-style replacement or direct-fit blade for metal-cutting bandsaws requiring an 89-inch welded blade in 0.5-inch width. Verify your saw's wheel diameter and blade guide spacing to confirm fitment before installation.

Installation Notes

Blade installation should be performed by a qualified metalworking technician familiar with bandsaw blade tensioning and tracking procedures. Disconnect and lock out power to the saw before removing or installing any blade. Follow the saw manufacturer's specified tension range for the blade width and thickness in use — do not over-tension, as this accelerates tooth fatigue and wheel bearing wear. Confirm blade tracking and guide alignment before resuming cutting operations.
