Starrett 13840 Band Saw Blade Coil 3/4 in 100 Ft 6 Tpi

Product Description

The STARRETT 13840 is a carbon steel band saw blade coil stock designed for continuous cutting operations in professional shop and industrial environments. The coil format allows fabricators and machinists to cut blades to custom lengths, making it a practical choice for facilities running multiple saw sizes. The blade measures 3/4 inches wide and 0.032 inches thick, with a 6 teeth per inch (TPI) constant pitch and a raker tooth set. The flexible back design reduces fatigue cracking during operation, extending blade service life under repeated use. Typical installers are machinists, metalworkers, and shop technicians who weld their own blades in-house.

This coil stock is suited for contour cutting applications where a consistent, straight tooth form delivers controlled chip removal. The 6 TPI pitch is effective on medium-section stock, balancing cut speed with surface finish. The raker set pattern alternates teeth in a right-left-straight sequence, which clears chips efficiently and reduces heat buildup in the cut zone. The 100-foot coil length provides enough material to yield multiple blades, making it cost-effective for shops that maintain a high blade turnover or service band saws of varying wheel diameters.

Key Features

• Carbon steel construction with flexible back for resistance to fatigue cracking
• 6 TPI constant pitch for consistent chip load on medium-section workpieces
• Raker tooth set for efficient chip clearance and reduced heat in the kerf
• Straight tooth form and straight rake angle for controlled, predictable cuts
• Contour cutting capable, suitable for curved and irregular cut profiles
• 100-foot coil yields multiple custom-length blades from a single stock unit

Compatibility

Designed as a coil stock replacement for band saws accepting 3/4-inch wide blades with a 0.032-inch blade thickness. Suitable for shops that weld custom-length blades for vertical or horizontal band saws of compatible wheel and guide configurations.

Installation Notes

Blade welding and grinding should be performed by a qualified machinist or toolroom technician using a band saw blade welder set to the appropriate flash and upset settings for carbon steel stock. Disconnect and lock out the band saw from its power source before installing or tensioning any blade. Verify that blade width, thickness, and tooth set are compatible with the saw's guide assemblies and blade guards before running the machine. Follow the saw manufacturer's tensioning guidelines and confirm blade tracking before resuming production cuts.
