Starrett 20692 Welded Bandsaw Blade 4-6 Tpi Bi-metal

Product Description

The STARRETT 20692 is a welded bi-metal bandsaw blade from the Intenss PRO series, engineered for cutting ferrous and non-ferrous metal in professional shop and production environments. The blade measures 154 inches in length and 3/4 inch in width, with a thickness of 0.035 inches. Its variable pitch tooth pattern spans 4 to 6 TPI, reducing harmonic vibration and delivering smoother cuts across varying material thicknesses. The high speed steel teeth feature a positive rake angle and raker tooth set, optimized for aggressive chip removal in metal-cutting applications. Licensed machinists, fabricators, and maintenance technicians are the primary installers.

This blade is suited for horizontal and vertical metal-cutting bandsaws with a blade capacity matching the 154-inch loop length and 3/4-inch blade width. The flexible back construction allows it to run continuously on powered bandsaws without premature fatigue cracking. Material applications include structural steel, angle iron, tubing, aluminum, brass, and other ferrous and non-ferrous stock. It is not designed for contour cutting. Typical use cases include production cut-off operations and structural fabrication shops where consistent, repeatable cuts are required across a range of metal cross-sections.

Key Features

• Variable pitch 4 to 6 TPI tooth pattern reduces vibration and improves cut finish on varying stock thicknesses
• Bi-metal construction with high speed steel teeth provides extended tooth life compared to carbon-steel blades
• Positive rake angle promotes aggressive, efficient chip removal in metal cutting
• Raker tooth set maintains consistent kerf width and reduces blade drift
• Flexible back design resists fatigue cracking during continuous bandsaw operation
• Welded blade loop eliminates mechanical joints that can cause vibration or breakage at the weld zone

Compatibility

Designed for powered metal-cutting bandsaws requiring a 154-inch welded blade loop that is 3/4 inch wide and 0.035 inches thick. Verify blade tension specifications and wheel diameter capacity on the host saw before installation.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Disconnect and lock out power to the bandsaw before removing the old blade or mounting a new one. Confirm proper blade tracking and set blade tension according to the saw manufacturer's specifications for 3/4-inch bi-metal blades. Always wear cut-resistant gloves when handling coiled or uncoiled bandsaw blades.
