Starrett 21222 Welded Bandsaw Blade 5-8 Tpi Bi-metal

Product Description

The STARRETT 21222 is a welded bi-metal bandsaw blade engineered for continuous-loop cutting on stationary band saw machines. Measuring 15 feet 6 inches in length and 1-1/4 inches wide with a 0.042-inch thickness, this blade carries a variable 5 to 8 teeth-per-inch pitch pattern that transitions cutting load across the tooth gullets, reducing vibration and extending blade life. The high speed steel teeth are set in a raker pattern with a positive rake angle, promoting aggressive chip evacuation on both ferrous and non-ferrous metals. It is part of the Intenss PRO series and is installed by machinists and metal fabricators in shop and production environments.

This blade is suited for cutting ferrous metals such as mild steel, alloy steel, and structural shapes, as well as non-ferrous metals including aluminum, brass, and copper. The variable pitch design handles varying cross-sections and wall thicknesses without chatter, making it a practical choice for structural tube, solid bar, and plate stock. The flexible back construction allows the blade to track smoothly around the bandsaw wheels without stress cracking over extended run time.

Key Features

• Bi-metal construction with high speed steel teeth bonded to a flexible alloy back for durability and flex resistance
• Variable 5 to 8 TPI pitch reduces harmonic vibration and extends blade service life on varied cross-sections
• Raker tooth set with positive rake angle promotes aggressive, clean chip removal in ferrous and non-ferrous metal
• 1-1/4 inch width and 0.042-inch thickness suited for medium to large-capacity horizontal and vertical band saws
• Straight tooth form and flexible back type support consistent tracking and reduced blade fatigue
• Welded loop construction shipped ready to install with no field welding required

Compatibility

Designed for use on stationary band saw machines that accept a 15-foot 6-inch blade loop in 1-1/4 inch width. Suitable for cutting ferrous and non-ferrous metal stock as specified by the Intenss PRO series application ratings.

Installation Notes

Band saw blade installation should be performed by a qualified machinist or fabricator with the machine fully de-energized and locked out per applicable safety procedures. Verify wheel diameter, blade guide spacing, and tension specifications on the host machine before mounting. Wear cut-resistant gloves when handling coiled or uncoiled blade stock. After installation, run the blade at reduced feed rate for a brief break-in period before applying full cutting load.
