Starrett 21568 Bi-metal Bandsaw Blade 11ft6in 1in 3-4 Tpi

Product Description

The STARRETT 21568 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in professional shop and industrial environments. Built on the Intenss PRO-VTH series platform, it measures 138 inches long, 1 inch wide, and 0.035 inches thick. The blade runs a variable 3-4 TPI pitch with a positive rake angle and ground, straight-form raker-set teeth backed by an M42 high speed steel tooth material. The flexible back construction reduces blade fatigue during extended contour-cutting operations. At 3.5 pounds, the blade is sized for floor-standing vertical bandsaws used in ferrous metal and exotic steel cutting.

This blade is suited for professional metal fabricators, maintenance technicians, and tool-and-die shops running vertical bandsaws on steel and exotic steel workpieces. The variable pitch tooth pattern dampens harmonic vibration, making it effective on solid bar stock, structural shapes, and tubing. Contour cutting is supported by the blade geometry, giving operators the ability to follow curved cut lines without significant blade deflection. It is a direct replacement or upgrade choice wherever a 138-inch by 1-inch bi-metal bandsaw blade is specified.

Key Features

• M42 high speed steel teeth for extended cutting life on steel and exotic alloys
• Variable 3-4 TPI pitch reduces vibration and improves surface finish on metal cuts
• Positive rake angle increases chip clearance and cutting aggression on ferrous stock
• Ground cutting edge delivers consistent tooth geometry and uniform kerf
• Flexible back construction resists fatigue cracking during contour and radius cuts
• Raker tooth set provides balanced chip removal for general-purpose metal cutting

Compatibility

Designed as an OEM-style replacement bandsaw blade for vertical bandsaws accepting a 138-inch by 1-inch blade with 0.035-inch blade thickness.

Installation Notes

Bandsaw blade replacement is typically performed by a qualified shop technician or machinist. Disconnect and lock out power to the bandsaw before opening blade guards or removing the old blade. Use proper blade-folding technique and cut-resistant gloves when handling the coiled blade. Verify blade guides, thrust bearings, and wheel tracking alignment after installation before resuming cuts.
