Starrett 15993 Welded Bandsaw Blade 4-6 Tpi Bi-metal

Product Description

The STARRETT 15993 is a welded bi-metal bandsaw blade engineered for continuous cutting in metal fabrication and industrial sawing applications. It measures 13 feet 3 inches in length, 1 inch in width, and 0.035 inches in thickness. The blade features a variable pitch tooth pattern ranging from 4 to 6 TPI, which reduces harmonic vibration and helps prevent blade loading during cuts. High speed steel M42 grade teeth are electron-beam welded to a flexible alloy back, delivering edge retention at higher cutting speeds. Licensed HVAC techs, machinists, and fabricators installing this blade on horizontal or vertical band saws will find it suited for demanding production environments.

The STARRETT 15993 is designed for contour and straight cutting of ferrous and non-ferrous metals including structural steel, stainless, aluminum, and copper alloys. Its raker tooth set and positive rake angle promote aggressive chip clearing, making it well suited for medium-to-heavy section cuts in job shop and production environments. The flexible back construction allows the blade to run continuously on most industrial band saw machines without fatigue cracking at the weld joint.

Key Features

• Variable pitch 4 to 6 TPI reduces vibration and improves cut finish on varying cross-sections
• M42 high speed steel teeth provide extended edge life on hard ferrous metals
• Bi-metal construction bonds HSS teeth to a flexible alloy back for durability
• Raker tooth set with positive rake angle promotes efficient chip evacuation
• Rated for both ferrous metal and non-ferrous metal material applications
• Contour cutting capable for curved or irregular workpiece profiles

Compatibility

Designed as a direct-fit welded bandsaw blade replacement for industrial band saw machines accepting a 1 inch wide blade in the 13 feet 3 inch loop length. Suitable for ferrous and non-ferrous metal cutting applications.

Installation Notes

Blade installation should be performed by a qualified machinist or maintenance technician with the band saw powered off, locked out, and tagout procedures followed per OSHA 29 CFR 1910.147. Verify wheel diameter, blade guide spacing, and blade tension specification on the host saw before mounting. Inspect the weld joint for any visible defects before tensioning. Always wear cut-resistant gloves when handling bandsaw blades.
