Starrett 20647 Welded Bandsaw Blade 15 Ft Bi-metal

Product Description

The STARRETT 20647 is a welded bi-metal bandsaw blade engineered for demanding cutting applications in metal fabrication and industrial environments. Part of the Intenss PRO series, this blade measures 15 feet in length and 1-1/4 inches in width, with a blade thickness of 0.042 inches. The variable pitch tooth design, ranging from 2 to 3 teeth per inch, reduces harmonic vibration during cuts and helps prevent tooth stripping on irregular or variable cross-section workpieces. High speed steel teeth bonded to a flexible alloy back deliver the edge retention of HSS with the fatigue resistance of a flexible body. Licensed machinists, millwrights, and metal fabricators working with structural stock will find this blade spec appropriate for production-level bandsaw use.

This blade is suited for cutting ferrous metals such as carbon steel, alloy steel, and structural shapes, as well as non-ferrous metals including aluminum, brass, and copper. The raker tooth set and positive rake angle promote aggressive chip clearance, making this blade a practical choice for production cutting on horizontal and vertical metal-cutting bandsaws. The straight tooth form and variable pitch pattern work together to handle both solid bar stock and tubular or structural profiles. It is intended for professional shop use where blade life and cut quality on metal stock are primary concerns.

Key Features

• Bi-metal construction with high speed steel teeth for extended edge life on ferrous and non-ferrous metals
• Variable pitch 2-3 TPI design reduces vibration and chatter on structural and variable cross-section stock
• Raker tooth set with positive rake angle promotes efficient chip evacuation
• Flexible alloy back resists fatigue and cracking under continuous band tension
• Welded construction provides a consistent, pre-joined blade loop ready for immediate installation
• Intenss PRO series designed for high-production metal-cutting bandsaw environments

Compatibility

Designed for metal-cutting bandsaws that accept a 15-foot blade loop, 1-1/4 inches wide. Verify your machine's blade length, wheel diameter, and guide specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with metal-cutting bandsaw equipment. Disconnect and lock out power to the saw before mounting or removing a blade. Inspect blade guides, blade tension scale, and wheel condition before tensioning the new blade, and set tension according to the saw manufacturer's specification for a 1-1/4-inch blade width. Never exceed the rated blade speed for the material being cut.
