Starrett 20659 Welded Bandsaw Blade 4-6 Tpi Bi-metal

Product Description

The STARRETT 20659 is a welded bi-metal bandsaw blade engineered for cutting ferrous and non-ferrous metals on stationary band saws. Part of the Intenss PRO series, it measures 162 inches long and 1-1/4 inches wide with a 0.042-inch thickness. The blade uses a 4-6 TPI variable pitch pattern to reduce harmonic vibration and improve cut quality across a range of material cross-sections. High speed steel teeth are set in a raker configuration with a positive rake angle for aggressive, efficient material removal. A flexible back construction allows the blade to flex through the saw's wheel path without fatigue cracking. Licensed HVAC, plumbing, or metalworking professionals running structural stock or pipe on a 13-foot-6-inch frame band saw will find this blade suited to production-level cutting demands.

This blade is designed for use on industrial and commercial stationary band saws that accept a 162-inch blade length. It is suited for cutting ferrous metals such as structural steel, bar stock, and pipe, as well as non-ferrous materials including aluminum and copper. The variable pitch tooth form handles both solid sections and thin-walled tubing without tooth stripping. Typical users include metal fabrication shops, pipefitters, mechanical contractors, and maintenance technicians running floor-mounted band saws in shop environments.

Key Features

• Bi-metal construction with high speed steel teeth bonded to a flexible alloy steel back for extended blade life
• 4-6 TPI variable pitch reduces vibration and improves surface finish on varied material cross-sections
• Raker tooth set with positive rake angle for fast, efficient cuts in ferrous and non-ferrous metals
• Flexible back type resists fatigue and cracking through the saw wheel path during continuous use
• Straight tooth form provides consistent chip clearance on solid bar and structural stock
• Factory-welded loop ready to install without additional joining or brazing

Compatibility

Designed as an OEM-style replacement or direct-fit blade for stationary band saws requiring a 162-inch blade length with a 1-1/4-inch blade width. Suited for machines configured for ferrous and non-ferrous metal cutting applications.

Installation Notes

Blade installation should be performed by a qualified technician familiar with band saw tensioning and tracking procedures. Power down and lock out the saw at the main disconnect before opening blade guards or handling the blade. Set blade tension and tracking according to the band saw manufacturer specifications before making a cut. Wear cut-resistant gloves when handling coiled or uncoiled bandsaw blades, as the teeth present a laceration hazard.
