Starrett 20656 Welded Bandsaw Blade 3-4 Tpi Bi-metal

Product Description

The STARRETT 20656 is a welded bi-metal bandsaw blade from the Intenss PRO series, designed for continuous cutting in metal-cutting bandsaws. At 15 feet 8 inches in length and 1-1/4 inches wide, this blade is built for mid- to large-frame vertical or horizontal bandsaw machines. The blade runs at a variable pitch of 3 to 4 TPI with a raker tooth set and positive rake angle, which promotes efficient chip evacuation and smooth cutting in a range of metal stock profiles. The bi-metal construction pairs a flexible steel back with high-speed steel teeth, extending tooth life under demanding production conditions. Weighing 6.8 pounds, this blade is suited for professional metal fabrication and maintenance environments.

The STARRETT 20656 is intended for cutting ferrous and non-ferrous metals including structural steel, aluminum, copper, and similar stock. The variable pitch pattern reduces vibration and harmonic chatter across varying cross-sections, making it a practical choice for shops cutting both solid bar and tubing in the same setup. The 0.042-inch blade thickness and flexible back type allow the blade to track reliably on standard bandsaw wheel configurations without excessive stress at the weld joint. This blade is installed by machinists, fabricators, and maintenance technicians in job shop, production, and industrial service environments.

Key Features

• Bi-metal construction with high-speed steel teeth bonded to a flexible alloy steel back for extended service life
• Variable pitch 3-4 TPI reduces vibration and chatter when cutting varied cross-sections
• Raker tooth set with positive rake angle promotes aggressive chip removal in metal cutting
• Straight tooth form supports consistent, repeatable cuts in ferrous and non-ferrous materials
• Pre-welded loop format eliminates field welding and allows direct installation on compatible saws
• Intenss PRO series construction engineered for demanding industrial metal-cutting applications

Compatibility

Designed for use on bandsaw machines that accept a 15-foot 8-inch loop blade, 1-1/4 inches wide and 0.042 inches thick, for cutting ferrous and non-ferrous metal stock. Verify wheel span, blade guide clearance, and tension specifications on the host machine before installation.

Installation Notes

A qualified machinist or equipment technician should install bandsaw blades following the saw manufacturer's procedures. Disconnect and lock out electrical power to the bandsaw before changing blades. Set blade tension and tracking per the machine manufacturer's specifications, and confirm blade guides are properly adjusted to the blade width before resuming operation. Always wear cut-resistant gloves when handling bandsaw blades.
