Starrett 20628 Welded Bandsaw Blade 4-6 Tpi Bi-metal

Product Description

The STARRETT 20628 is a welded bi-metal bandsaw blade engineered for cutting ferrous and non-ferrous metals in industrial and production environments. It measures 11 feet 6 inches in length, 1 inch wide, and 0.035 inches thick, with a variable pitch tooth pattern rated at 4 to 6 teeth per inch (TPI). The high speed steel teeth are set in a raker pattern with a positive rake angle, promoting efficient chip evacuation and reduced cutting resistance. The flexible back construction helps absorb blade stress during continuous cutting cycles. This blade is part of the Intenss PRO series, suited to high-demand metal cutting applications.

This blade is intended for use on horizontal or vertical metal-cutting bandsaws with the appropriate wheel diameter and blade guide configuration to accommodate an 11 foot 6 inch blade. The 4 to 6 variable pitch TPI range is well-matched to cutting solid bar stock, structural shapes, and tubing in ferrous and non-ferrous materials. It is commonly installed by machinists, fabricators, and maintenance technicians in job shops, manufacturing facilities, and metalworking operations. Variable pitch reduces harmonic vibration during the cut, which extends blade life and improves surface finish on the workpiece.

Key Features

• Bi-metal construction with high speed steel teeth bonded to a flexible alloy back
• Variable pitch at 4 to 6 TPI reduces vibration and extends service life on mixed-section cuts
• Raker tooth set with positive rake angle for aggressive, efficient metal removal
• Straight tooth form suited to consistent cross-section cuts in bar, tube, and structural stock
• Flexible back type absorbs stress and resists fatigue through continuous cutting cycles
• Compatible with ferrous and non-ferrous metal applications in production or job-shop settings

Compatibility

Designed for metal-cutting bandsaw machines that accept a welded blade measuring 11 feet 6 inches in length, 1 inch wide, and 0.035 inches thick. Verify wheel spacing, blade guide clearance, and drive wheel diameter on the saw before installation.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with bandsaw blade tensioning and tracking procedures. Disconnect and lock out power to the saw before removing the old blade or mounting the new one. Confirm blade tension per the saw manufacturer's specification using the machine's onboard tension indicator or a blade tension gauge. Allow the blade to run under light load for the first few cuts to seat the teeth before applying full feed pressure.
