Starrett 15840 Band Saw Blade Coil 3/8 in Bi-metal

Product Description

The STARRETT 15840 is a bi-metal band saw blade coil stock designed for continuous-length cutting applications in metal fabrication, maintenance shops, and production environments. The coil measures 100 feet in length at 3/8 inch width and 0.025 inch thickness, providing a large supply that can be cut to fit a wide range of band saw machines. The blade combines an alloy steel back with high speed steel teeth for durability under repeated use. A variable pitch tooth pattern in the 8-12 TPI range reduces vibration and chatter, making it suitable for cutting varying cross-sections and material thicknesses without changing blades.

This coil stock is well suited for job shops and service operations that run multiple band saw frames or frequently re-blade machines. The 3/8 inch width makes it appropriate for contour cutting as well as straight cuts on ferrous and non-ferrous metals. The raker tooth set improves chip clearance and helps maintain consistent cut quality across longer production runs. Technicians who stock coil rather than pre-welded blades can weld custom lengths on-site to match specific saw wheel diameters and blade guides.

Key Features

• Bi-metal construction with alloy steel back and high speed steel teeth for extended blade life
• Variable pitch 8-12 TPI reduces vibration when cutting varied material profiles
• Raker tooth set promotes efficient chip evacuation and clean cuts
• 3/8 inch width supports contour cutting capability
• 100-foot coil stock allows custom blade lengths to be welded as needed
• Straight tooth form and straight rake angle for consistent, controlled cutting

Compatibility

Designed as a coil-stock replacement blade for band saw machines that accept 3/8 inch wide blades. Intended for use in shops equipped with a blade welder to produce custom-length blades from coil stock.

Installation Notes

Installation should be performed by a qualified technician familiar with band saw blade welding, grinding, and tensioning procedures. Power down and lockout the band saw before removing the old blade or installing a new one. When welding coil stock to length, follow the saw manufacturer's recommended tension settings for the blade width and material being cut. Inspect blade guides, wheel alignment, and blade tracking before returning the machine to service.
