Starrett 20653 Welded Bandsaw Blade 3-4 Tpi Bi-metal

Product Description

The STARRETT 20653 is a welded bi-metal bandsaw blade engineered for continuous cutting of ferrous and non-ferrous metals in industrial and shop environments. At 174 inches in total length and 1-1/4 inches wide, this blade fits standard 14-foot 6-inch bandsaw machines. The bi-metal construction pairs a flexible backing with high-speed steel teeth at a variable 3-4 TPI pitch, allowing the blade to transition efficiently across varying material cross-sections. A raker tooth set and positive rake angle reduce cutting resistance and extend blade life on demanding stock. Licensed HVAC, machine-shop, and fabrication technicians rely on this blade for straight, controlled cuts through structural metals and pipe stock.

This blade is suited for metal-cutting vertical bandsaws found in commercial fabrication shops, HVAC mechanical rooms, and plumbing or pipefitting operations. The variable-pitch tooth pattern minimizes vibration and chatter when cutting structural steel, angle iron, tubing, copper, aluminum, and other ferrous and non-ferrous stock. It is not designed for contour or curved cutting applications. Its straight tooth form and raker set make it the preferred choice for production-volume straight cuts where consistent finish and blade longevity matter.

Key Features

• Bi-metal construction: flexible backing with high-speed steel teeth for durability and resistance to blade fatigue
• Variable pitch 3-4 TPI reduces vibration and chatter across different material thicknesses
• Positive rake angle promotes aggressive, efficient stock removal
• Raker tooth set supports chip clearance and consistent cut quality
• Straight tooth form optimized for linear, non-contour metal cutting
• Intenss PRO series designed for high-demand ferrous and non-ferrous metal applications

Compatibility

Designed as a welded replacement bandsaw blade for metal-cutting bandsaws that accept a 14-foot 6-inch blade length. Suitable for cutting ferrous metal and non-ferrous metal stock as stated by the manufacturer.

Installation Notes

Blade installation should be performed by a qualified technician with the bandsaw fully powered down and the machine isolated from its power source before beginning. Verify wheel diameter, blade guide clearance, and blade tension specifications on the specific saw before mounting. Always confirm blade tracking and tension are within the saw manufacturer's recommended range before resuming operation. Wear appropriate cut-resistant gloves and eye protection when handling or tensioning bandsaw blades.
