Starrett 15989 Bi-metal Bandsaw Blade 6-10 Tpi

Product Description

The STARRETT 15989 is a bi-metal welded bandsaw blade from the Intenss PRO series, designed for cutting ferrous and non-ferrous metals in industrial and trade shop environments. The blade measures 188 inches in total length and 3/4 inch in width, with a 0.035 inch thickness that provides a balance of flexibility and durability through the cut. High speed steel teeth are bonded to a flexible alloy back, giving the blade resistance to heat and wear during high-cycle production cutting. The variable pitch tooth pattern, ranging from 6 to 10 TPI, reduces vibration and harmonics across varying material thicknesses. This blade is installed by machinists and metal fabricators on horizontal and vertical band saws.

The 15989 is suited for use in machine shops, fabrication facilities, and maintenance operations where both ferrous and non-ferrous metal stock is cut regularly. The raker tooth set and positive rake angle promote aggressive, efficient chip removal in structural shapes, bar stock, tubing, and solid rounds. The variable pitch design makes it practical across a range of cross-sections without needing to change blades between jobs. This blade ships as a single factory-welded loop, ready to mount without additional welding.

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 harmonics for smoother cuts across varied material cross-sections
• Raker tooth set with positive rake angle promotes efficient chip evacuation in metal cutting applications
• Flexible back design resists fatigue cracking under continuous band saw cycling
• Straight tooth form provides consistent, repeatable cuts in ferrous and non-ferrous metals
• Factory-welded loop — no on-site welding required for installation

Compatibility

Designed as an OEM-style replacement welded bandsaw blade for metal-cutting horizontal and vertical band saws that accept a 188 inch blade loop with a 3/4 inch width.

Installation Notes

Bandsaw blade replacement should be performed by a qualified machinist or maintenance technician. Disconnect and lock out power to the saw before opening blade guards or handling the blade. Verify that wheel diameter and blade guide spacing on the saw are compatible with the 188 inch loop length and 3/4 inch width before mounting. Follow the saw manufacturer's tensioning guidelines — improper tension causes premature blade fatigue and weld failure.
