Starrett 20624 Welded Bandsaw Blade 3-4 Tpi Bi-metal

Product Description

The STARRETT 20624 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in professional shop and industrial environments. Measuring 14 feet 6 inches in length, 1 inch wide, and 0.035 inches thick, this blade features a variable pitch tooth pattern at 3 to 4 TPI, which helps reduce vibration and harmonic chatter during cuts. The high speed steel teeth are set in a raker configuration with a positive rake angle for aggressive, efficient material removal. Machinists, fabricators, and maintenance technicians install this blade on vertical or horizontal bandsaws sized to accept the 14-foot 6-inch loop length.

This blade is rated for cutting both ferrous and non-ferrous metals and belongs to the Intenss PRO series, which is designed for production-level cutting cycles on structural steel, tubing, angle iron, aluminum extrusions, and similar stock. The flexible back construction allows the blade to endure the continuous flexing stress of bandsaw wheel contact without premature fatigue cracking. It is well suited to shops running general-purpose metal fabrication, HVAC duct and pipe prep, or maintenance and repair operations where a single blade must handle a range of material types and cross-sections.

Key Features

• Variable pitch 3 to 4 TPI tooth pattern reduces vibration and extends blade life in mixed-material cutting
• Bi-metal construction pairs a flexible alloy steel back with high speed steel teeth for durability and edge retention
• Raker tooth set with positive rake angle promotes fast, clean chip evacuation
• Flexible back type resists fatigue cracking under continuous bandsaw wheel flex
• Rated for both ferrous and non-ferrous metal applications
• Factory-welded loop — no field joining required before installation

Compatibility

Designed to fit bandsaws that accept a 14-foot 6-inch blade loop with a 1-inch wide, 0.035-inch thick profile. Confirm wheel diameter, blade guide spacing, and throat capacity on the target machine before ordering.

Installation Notes

Bandsaw blade replacement should be performed by a qualified machinist or maintenance technician with the machine powered down, locked out, and tagged per OSHA lockout/tagout procedures. Inspect blade guides, thrust bearings, and wheel tires for wear before installing the new blade. Tension the blade according to the bandsaw manufacturer's specifications and run the blade unloaded for a short break-in period before cutting under full load. Wear cut-resistant gloves when handling the coiled blade.
