Starrett 21566 Welded Bandsaw Blade 11 Ft 1 in 3-4 Tpi

Product Description

The STARRETT 21566 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in professional shop environments. Stretching 11 feet in length and measuring 1 inch wide by 0.035 inches thick, this blade belongs to the Intenss PRO-VTH series. The tooth edge is ground from M42 high speed steel with a variable pitch of 3 to 4 TPI and a positive rake angle, combining aggressive stock removal with reduced vibration. A raker tooth set and straight tooth form deliver consistent chip evacuation on ferrous and exotic steel workpieces. This blade is sold as a single welded loop ready for installation.

This blade is suited for contour cutting and straight resawing on vertical bandsaw machines found in metal fabrication shops, maintenance facilities, and production environments. The flexible back construction allows it to run on machines with appropriate wheel diameters for an 11-foot blade. Typical applications include cutting carbon steel, alloy steel, stainless, and exotic steel stock. Licensed machinists and metal fab technicians are the primary installers and operators.

Key Features

• M42 high speed steel tooth material for extended cutting life in hard metals
• Variable pitch 3 to 4 TPI reduces harmonics and vibration during the cut
• Positive rake angle promotes aggressive feed rates on steel and exotic alloys
• Raker tooth set with straight tooth form for efficient chip clearance
• Ground cutting edge for consistent tooth geometry out of the box
• Flexible back construction compatible with standard vertical bandsaw wheel configurations

Compatibility

Designed as a replacement welded bandsaw blade for vertical metal-cutting bandsaws that accept an 11-foot blade loop 1 inch wide and 0.035 inches thick. Intended for cutting steel and exotic steel materials.

Installation Notes

Blade installation should be performed by a qualified machinist or shop technician with the bandsaw fully powered down and locked out per LOTO procedures. Verify that wheel diameter, blade guides, and blade tension settings on the machine are appropriate for a 1-inch-wide, 0.035-inch-thick blade before tensioning. Always wear cut-resistant gloves when handling uncoiled or pre-welded bandsaw blades. Inspect the weld joint for integrity before placing the blade in service.
