Starrett 13689 Welded Bandsaw Blade 6-10 Tpi Bi-metal

Product Description

The STARRETT 13689 is a welded bi-metal bandsaw blade from the Intenss PRO series, designed for continuous-duty metal cutting on horizontal and vertical bandsaws. It measures 12 feet 6 inches in length, 1 inch in width, and 0.035 inches in thickness. The variable pitch tooth pattern runs 6 to 10 TPI, reducing harmonic vibration and chatter during the cut. High speed steel teeth are electron-beam welded to a flexible alloy steel back, combining edge hardness with backbone toughness. Licensed metalworking technicians and tool room machinists are the primary installers and users of this blade.

The 13689 is suited for ferrous and non-ferrous metal cutting in production and job-shop environments. The variable 6-to-10 TPI pitch and positive rake angle make it effective across a range of cross-sections, from thin-wall tubing to solid bar stock. The raker tooth set provides efficient chip clearance on structural steel, aluminum, copper, and similar materials. It is a welded blade supplied as a single loop, ready to mount directly on machines with matching wheel and guide specifications.

Key Features

• Bi-metal construction: high speed steel teeth bonded to a flexible alloy back for long service life
• Variable pitch 6 to 10 TPI reduces vibration and improves cut quality across varied stock sizes
• Positive rake angle promotes aggressive, efficient cutting on ferrous and non-ferrous metals
• Raker tooth set delivers consistent chip evacuation during straight cuts
• Flexible back type resists fatigue cracking under continuous bandsaw wheel flex
• Intenss PRO series designed for demanding production cutting applications

Compatibility

Designed as a direct-mount welded bandsaw blade replacement for horizontal and vertical metal-cutting bandsaws requiring a 12-foot 6-inch loop, 1-inch width, and 0.035-inch blade thickness. Suitable for cutting ferrous metals and non-ferrous metals as specified by the manufacturer.

Installation Notes

Bandsaw blade installation and tensioning should be performed by qualified personnel with the machine powered down, locked out, and tagged out per OSHA lockout/tagout procedures. Verify wheel diameter, blade guide spacing, and throat capacity match the blade dimensions before mounting. Blade tracking and tension must be set according to the bandsaw manufacturer specifications before resuming operation. Wear cut-resistant gloves when handling the coiled blade during installation.
