Starrett 20637 Welded Bandsaw Blade 5-8 Tpi Bi-metal

Product Description

The STARRETT 20637 is a welded bi-metal bandsaw blade built for continuous cutting of ferrous and non-ferrous metals. Part of the Intenss PRO series, it measures 150 inches in length, 1 inch wide, and 0.035 inches thick, with a variable pitch tooth pattern ranging from 5 to 8 TPI. The bi-metal construction pairs a flexible alloy steel back with high speed steel teeth, giving the blade durability under repeated stress while maintaining edge retention. This blade is suited for professional metal fabrication shops and trade service environments where consistent, accurate band sawing is required.

This blade is designed for metal-cutting vertical or horizontal bandsaws with a 150-inch blade capacity. It handles both ferrous metals such as mild steel and structural steel, and non-ferrous metals such as aluminum and copper. The variable pitch tooth pattern reduces harmonic vibration during cutting, which improves cut quality and extends blade life across varying material cross-sections. It is a practical choice for shops cutting round stock, flat bar, tubing, and structural profiles in production or maintenance settings.

Key Features

• Bi-metal construction: flexible alloy steel back with high speed steel teeth for extended wear resistance
• Variable pitch 5-8 TPI tooth pattern reduces vibration and improves cut quality across multiple material profiles
• Raker tooth set with positive rake angle for efficient chip clearance in metal cutting
• Straight tooth form suited for general-purpose contour and straight cuts in ferrous and non-ferrous metals
• Flexible back type absorbs blade flex stress, reducing fatigue cracks during extended use
• Part of the Intenss PRO series, designed for demanding production cutting applications

Compatibility

Designed as a direct-fit welded replacement blade for metal-cutting bandsaws requiring a 150-inch bi-metal blade with a 1-inch width and 0.035-inch thickness. Suitable for machines cutting ferrous and non-ferrous metal stock.

Installation Notes

Bandsaw blade installation should be performed by a qualified technician with the machine fully powered down and locked out before handling. Verify blade tension and blade guide settings according to the saw manufacturer specifications before resuming operation. Wear cut-resistant gloves when handling the coiled blade. Confirm that blade width, thickness, and length are compatible with your specific saw model before mounting.
