Starrett 20623 Welded Bandsaw Blade 3-4 Tpi Bi-metal

Product Description

The STARRETT 20623 is a welded bi-metal bandsaw blade engineered for continuous cutting of ferrous and non-ferrous metals in industrial and trade shop environments. Measuring 13 feet 6 inches in length and 1 inch wide with a 0.035-inch thickness, this blade fits standard vertical and horizontal band saws sized for that loop length. The variable pitch design runs at 3 to 4 TPI, reducing harmonic vibration during the cut and extending blade life on interrupted or varying cross-sections. High speed steel teeth are electron-beam welded to a flexible alloy steel back, giving the blade both edge hardness and body fatigue resistance across long production runs.

This blade is suited for metal fabrication shops, pipe and structural steel cutting, maintenance and repair operations, and production environments where consistent ferrous and non-ferrous stock removal is required. The raker tooth set and positive rake angle deliver efficient chip clearance on solid bar, tubing, angle iron, aluminum extrusions, and similar stock profiles. It is a direct-fit replacement for shop band saws that accept a 13-foot 6-inch welded loop blade in the 1-inch width class. Machinists, fabricators, and industrial maintenance technicians are the primary installers and users.

Key Features

• Bi-metal construction: high speed steel teeth bonded to a flexible alloy steel back for durability and fatigue resistance
• Variable pitch 3-4 TPI reduces vibration and noise during cutting of varying cross-sections
• Raker tooth set with positive rake angle promotes aggressive chip clearance
• Straight tooth form delivers consistent, repeatable cuts on solid and hollow stock
• Flexible back resists cracking and work-hardening over extended blade life
• Rated for both ferrous metals and non-ferrous metals including aluminum and copper alloys

Compatibility

Designed as a welded loop replacement blade for vertical or horizontal band saws accepting a 1-inch-wide blade in a 13-foot 6-inch loop length. Suitable for ferrous metal and non-ferrous metal material applications per manufacturer specification.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician with the band saw powered off and locked out per OSHA lockout/tagout procedures. Verify wheel diameter, blade guide spacing, and blade tension spec on the host machine before mounting. Wear cut-resistant gloves when handling the coiled blade. After tensioning, run the blade unloaded briefly to confirm tracking before beginning cuts.
