Starrett 20655 Welded Bandsaw Blade 3-4 Tpi Bi-metal

Product Description

The STARRETT 20655 is a welded bi-metal bandsaw blade from the Intenss PRO series, built for cutting ferrous and non-ferrous metals in professional fabrication and metalworking environments. The blade measures 186 inches in length and 1-1/4 inches in width, with a thickness of 0.042 inches. It runs a variable pitch pattern at 3 to 4 teeth per inch, which helps reduce vibration and harmonic noise during cuts. The high speed steel tooth tips are set in a raker pattern with a positive rake angle for aggressive, efficient material removal. This blade is installed and serviced by machinists, fabricators, and metal tradespeople working with vertical or horizontal band saws.

The STARRETT 20655 is suited for cutting a wide range of ferrous and non-ferrous metals in production and job-shop settings. The variable pitch design makes it effective on both solid bar stock and structural profiles where consistent chip load control matters. The flexible back type allows the blade to run on standard bandsaw wheel configurations without fatigue cracking over normal service cycles. The Intenss PRO series targets demanding metal-cutting applications where blade life and cut quality are priorities.

Key Features

• Bi-metal construction with high speed steel teeth bonded to a flexible backing for extended blade life
• Variable pitch at 3 to 4 TPI reduces vibration and improves cut finish on metal stock
• Raker tooth set with positive rake angle promotes aggressive chip clearing
• Straight tooth form provides consistent cutting geometry across ferrous and non-ferrous materials
• Flexible back type resists fatigue cracking during continuous operation
• Welded construction ensures a seamless loop for balanced tracking on bandsaw wheels

Compatibility

Designed as an OEM-style welded bandsaw blade replacement for horizontal and vertical metal-cutting bandsaws that accept a 186-inch blade loop at 1-1/4 inches wide.

Installation Notes

Installation should be performed by a qualified machinist or fabricator familiar with bandsaw blade tensioning and wheel alignment procedures. Power down and lockout the bandsaw completely before removing the worn blade or installing the new one. Verify wheel guides, blade guards, and tension settings match the blade width and thickness specifications before operation. Follow the machine manufacturer's tensioning guidelines for 1-1/4-inch bi-metal blades to avoid premature weld fatigue.
