Starrett 20621 Welded Bandsaw Blade 12 Ft Bi-metal

Product Description

The STARRETT 20621 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in fabrication and maintenance environments. Part of the Intenss PRO series, this blade measures 12 feet in length, 1 inch wide, and 0.035 inches thick. It runs a variable pitch of 3 to 4 TPI with a raker tooth set and positive rake angle, which reduces vibration and improves chip evacuation during cuts. The high-speed steel teeth are electron-beam welded to a flexible alloy back, giving the blade resistance to tooth strippage on interrupted cuts and uneven stock. Licensed HVAC, plumbing, and general mechanical contractors, as well as fabrication shop machinists, rely on this style of blade for consistent performance through ferrous and non-ferrous materials.

This blade is suited for horizontal and vertical bandsaw machines used in light industrial, commercial, and jobsite settings. It is designed to cut ferrous metals such as structural steel, angle iron, and pipe, as well as non-ferrous metals including aluminum, copper, and brass. The variable pitch pattern makes it a practical choice when cutting a range of material profiles and wall thicknesses without changing blades. It is sold as a single welded loop, ready to mount on compatible machines accepting a 12-foot blade with a 1-inch width capacity.

Key Features

• Bi-metal construction with high-speed steel teeth bonded to a flexible alloy back for extended blade life
• Variable pitch 3 to 4 TPI reduces vibration and harmonic noise during cuts
• Positive rake angle improves cutting aggression and chip clearance on metal stock
• Raker tooth set provides consistent chip removal in solid and structural sections
• Straight tooth form maintains predictable feed rates across ferrous and non-ferrous materials
• Intenss PRO series design targets production-level metal-cutting demands

Compatibility

Designed as a direct-mount welded bandsaw blade for horizontal and vertical metal-cutting bandsaws accepting a 12-foot blade length, 1-inch blade width, and 0.035-inch blade thickness. Suitable for cutting ferrous metal and non-ferrous metal workpieces.

Installation Notes

Installation should be performed by a qualified machinist or technician following the bandsaw manufacturer's blade-change procedure. Disconnect and lock out power to the saw before removing the existing blade or mounting the new one. Verify blade tension and tracking per the machine's specification before resuming cuts. Wear cut-resistant gloves when handling uncoiled or unpackaged bandsaw blades.
