Starrett 00109 Welded Bandsaw Blade 2-3 Tpi Bi-metal

Product Description

The STARRETT 00109 is a welded bi-metal bandsaw blade engineered for demanding metal-cutting applications in industrial and fabrication environments. Measuring 19 feet 2 inches in length and 1-1/2 inches wide with a 0.05-inch thickness, this blade runs on large vertical or horizontal band saws used by metal fabricators, machinists, and maintenance technicians. The variable 2-3 TPI pitch pattern reduces harmonic vibration and helps control chip load across varying material cross-sections. High-speed steel teeth are ground to a positive rake angle with a raker tooth set for aggressive, consistent chip clearance on ferrous materials.

This blade is built for cutting steel, stainless steel, and exotic steel alloys where a standard carbon blade would wear prematurely. The Primalloy series bi-metal construction bonds a high-speed steel tooth edge to a flexible alloy steel back, giving the blade resistance to tooth strippage under interrupted cuts and allowing it to flex around bandsaw wheels without fatigue cracking. It is well suited to production cutting of structural shapes, bar stock, tubing, and plate in job shop, maintenance, and heavy fabrication settings. The straight tooth form and ground cutting edge deliver a clean, dimensionally consistent kerf.

Key Features

• Variable 2-3 TPI pitch reduces vibration and controls chip load across varying cross-sections
• Bi-metal Primalloy construction bonds high-speed steel teeth to a flexible alloy steel back
• Positive rake angle and raker tooth set promote aggressive chip evacuation
• Ground cutting edge delivers consistent kerf geometry and extended tooth life
• Flexible back resists fatigue cracking through repeated wheel contact
• Rated for steel, stainless steel, and exotic steel material applications

Compatibility

Designed to fit horizontal and vertical band saws accepting a 19-foot 2-inch blade loop, 1-1/2 inches wide. Verify wheel diameter, blade guide spacing, and drive wheel capacity before installation to confirm fitment with your specific saw.

Installation Notes

Bandsaw blade installation and tensioning should be performed by a qualified machinist or maintenance technician with the saw fully de-energized and locked out per OSHA lockout/tagout procedures. Wear cut-resistant gloves when handling and coiling the blade. Set blade tension and guide clearances according to the saw manufacturer specifications for the blade width. Allow a short break-in period at reduced feed pressure on initial cuts to seat the tooth geometry.
