Starrett 15520 Welded Bandsaw Blade 11 Ft Bi-metal

Product Description

The STARRETT 15520 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in professional shop environments. Measuring 11 feet in length and 1 inch wide with a 0.035 inch thickness, this blade is built around a flexible back with high speed steel teeth set in a raker pattern. The variable pitch design spans 6 to 10 TPI, reducing harmonic vibration and improving chip evacuation across a range of material thicknesses. It is part of the Intenss PRO series and is intended for installation by machinists, fabricators, and maintenance technicians running vertical or horizontal band saws.

This blade is suited for cutting ferrous metals such as mild steel, alloy steel, and structural shapes, as well as non-ferrous metals including aluminum, brass, and copper. The variable pitch tooth geometry makes it effective for interrupted cuts and varying cross-sections where a fixed-pitch blade would chatter or bind. Typical use cases include job shops, maintenance facilities, and fabrication operations where a single blade needs to handle mixed material stock.

Key Features

• Bi-metal construction with high speed steel teeth bonded to a flexible alloy back for extended blade life
• Variable pitch 6 to 10 TPI reduces vibration and improves surface finish on varied material thicknesses
• Raker tooth set with positive rake angle promotes aggressive, efficient chip removal
• Straight tooth form delivers consistent, repeatable cuts on ferrous and non-ferrous metal stock
• Flexible back resists fatigue cracking through continuous blade cycling
• Welded construction provides a consistent joint with no weak points from mechanical fasteners

Compatibility

Designed as an OEM-style replacement or upgrade blade for horizontal and vertical band saws accepting an 11-foot welded bi-metal blade that is 1 inch wide and 0.035 inch thick.

Installation Notes

Blade installation should be performed by a qualified machinist or maintenance technician with the saw fully de-energized and locked out per OSHA lockout/tagout procedures. Verify blade tension and tracking adjustment per the saw manufacturer's guidelines before resuming operation. Wear cut-resistant gloves when handling the blade, as the teeth present a laceration hazard during coiling and uncoiling. Inspect blade guides and thrust bearings for wear before installing a new blade to avoid premature tooth damage.
