Starrett 20640 Welded Bandsaw Blade 5-8 Tpi Bi-metal

Product Description

The STARRETT 20640 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in professional shop environments. Part of the Intenss PRO series, it measures 14 feet 6 inches in length, 1 inch in width, and 0.035 inches in thickness. The blade features a variable pitch tooth pattern in the 5 to 8 TPI range, which reduces harmonic vibration and helps prevent tooth stripping when cutting variable cross-sections. The high-speed steel teeth are set in a raker pattern with a positive rake angle for aggressive, consistent stock removal. A flexible back construction allows the blade to absorb tension cycles and extend service life on high-production bandsaws.

This blade is suited for ferrous and non-ferrous metal cutting on vertical or horizontal bandsaw machines that accept a 14-foot 6-inch blade. Typical applications include structural steel, tube, pipe, solid bar, and angle iron. The variable pitch design is particularly effective when workpiece cross-sections change during the cut, such as with structural profiles or bundled stock. It is commonly installed in industrial, fabrication, and maintenance-repair-operations settings where consistent cut quality and blade longevity are priorities.

Key Features

• Bi-metal construction with high-speed steel teeth bonded to a flexible alloy steel back for extended blade life
• Variable pitch 5-8 TPI tooth pattern reduces vibration and minimizes tooth stripping on irregular cross-sections
• Raker tooth set with positive rake angle promotes fast, controlled chip evacuation
• Straight tooth form provides consistent cut geometry on ferrous and non-ferrous metals
• Flexible back type absorbs saw wheel stress and resists fatigue cracking during high-cycle use
• Part of the Intenss PRO series, designed for heavy-duty production bandsaw work

Compatibility

Designed as a direct-fit welded replacement blade for bandsaw machines requiring a 14-foot 6-inch loop blade with a 1-inch blade width. Suitable for cutting ferrous metal and non-ferrous metal workpieces.

Installation Notes

Bandsaw blade replacement should be performed by a qualified technician familiar with the specific machine model. Disconnect and lock out power to the saw before removing the old blade or installing the new one. Verify wheel spacing, blade guides, and blade tension settings are adjusted to the manufacturer specifications for a 1-inch-wide blade before resuming operation. Wear cut-resistant gloves when handling coiled or uncoiled bandsaw blades.
