Starrett 20755 Welded Bandsaw Blade 4-6 Tpi Bi-metal

Product Description

The STARRETT 20755 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in fabrication and maintenance environments. It measures 118 inches in total length and 3/4 inches wide, with a blade thickness of 0.035 inches. The tooth material is M42 high speed steel, which delivers superior heat and wear resistance compared to standard HSS grades. Variable pitch at 4 to 6 TPI reduces vibration and harmonic chatter during the cut, improving surface finish and blade life. This blade is installed by machinists, fabricators, and maintenance technicians who run horizontal or vertical bandsaws on ferrous and non-ferrous stock.

The 20755 is suited for cutting ferrous metals such as structural steel, alloy bar stock, and tubing, as well as non-ferrous materials including aluminum and brass. The variable 4 to 6 TPI pitch and raker tooth set make it effective across a range of cross-sections. It is appropriate for production environments and job-shop use where consistent cuts on mixed metal stock are required. The straight tooth form and positive rake angle promote aggressive chip removal while keeping blade deflection low.

Key Features

• M42 bi-metal construction with high speed steel teeth for extended cutting life on hard metals
• Variable pitch 4 to 6 TPI reduces vibration and chatter for smoother cuts
• Raker tooth set provides consistent chip clearance on solid and structural stock
• Positive rake angle promotes efficient material removal on ferrous and non-ferrous metals
• Flexible back type resists fatigue cracking through continuous bandsaw operation
• Welded construction for true endless-band fitment on standard bandsaw machines

Compatibility

Designed for use on bandsaw machines accepting a 118-inch blade loop with a 3/4-inch width. Suitable for horizontal and vertical metal-cutting bandsaws configured for bi-metal blades. Cuts ferrous and non-ferrous metals per manufacturer material application data.

Installation Notes

Installation should be performed by a qualified technician familiar with bandsaw blade changes. Power down and lock out the machine before removing the old blade or installing the new one. Use blade tension and tracking settings specified by the bandsaw manufacturer for a 3/4-inch bi-metal blade. Wear cut-resistant gloves when handling the coiled blade to avoid laceration.
