Starrett 20661 Welded Bandsaw Blade 15 Ft 1-1/4 in 4-6 Tpi

Product Description

The STARRETT 20661 is a welded bi-metal bandsaw blade engineered for continuous, high-demand cutting in metal fabrication and general industrial environments. Stretching 15 feet in length and measuring 1-1/4 inches wide by 0.042 inches thick, this blade is built around the Intenss PRO series design, which pairs a flexible alloy steel back with high speed steel teeth for durability across a wide range of ferrous and non-ferrous metals. The 4 to 6 variable pitch TPI configuration reduces harmonics and vibration during the cut, producing a cleaner kerf and extending blade life compared to fixed-pitch designs. Licensed tradespeople and experienced fabricators working with band saws in production settings will find this blade sized for standard industrial machines.

The STARRETT 20661 is intended for use on horizontal and vertical band saws where a 15-foot blade loop is required. Its raker tooth set and positive rake angle make it effective on structural steel, tubing, solid bar stock, aluminum, and other non-ferrous stock. The variable pitch pattern handles interrupted cuts and varying cross-sections without the resonance issues common in single-pitch blades. This blade suits job shops, maintenance departments, and fabrication facilities cutting a mix of ferrous and non-ferrous materials in production volumes.

Key Features

• Bi-metal construction: flexible alloy steel back bonded with high speed steel teeth for long service life
• Variable pitch 4 to 6 TPI reduces vibration and noise during cutting
• Raker tooth set with positive rake angle for aggressive, efficient stock removal
• Straight tooth form suited to general-purpose ferrous and non-ferrous metal cutting
• Welded blade loop — 15 feet long, ready to install without field welding
• Intenss PRO series design optimized for production-level band saw applications

Compatibility

Designed for industrial band saws accepting a 15-foot blade loop that is 1-1/4 inches wide and 0.042 inches thick. Verify your machine's blade length, width, and thickness specifications before installation.

Installation Notes

Band saw blade installation should be performed by a qualified technician following the saw manufacturer's tensioning and tracking procedures. Power down and lock out the machine before removing the old blade or fitting the new one. Wear cut-resistant gloves when handling the coiled blade — the teeth are sharp and the blade can spring open quickly when uncoiled. Follow the saw manufacturer's recommended blade tension settings for the blade width; improper tension is a leading cause of premature blade failure and poor cut quality.
