Starrett 15847 Band Saw Blade Coil 0.5 in 100 Ft 18 Tpi Bi-metal

Product Description

The STARRETT 15847 is a bi-metal band saw blade coil stock designed for continuous-length cutting applications in metalworking and fabrication shops. The coil measures 100 feet in length and 0.5 inches wide with a blade thickness of 0.025 inches. Tooth material is high speed steel bonded to an alloy steel back, giving the blade edge durability on hard materials while the backing resists fatigue and cracking. At 18 teeth per inch with a constant pitch and wavy set, the blade is optimized for smooth cuts on thin-wall tubing, small-section bar stock, and similar workpieces.

This coil stock is intended for shops and service operations that cut blade stock to custom lengths for vertical or horizontal band saws. It supports contour cutting applications and uses a straight rake angle with a straight tooth form, making it suitable for general-purpose ferrous and non-ferrous metal cutting. The wavy set pattern distributes cutting force across multiple teeth, reducing blade vibration and improving cut finish on thin or bundled sections. Licensed blade grinders and maintenance shops commonly purchase coil stock to dress blades in-house to specific machine requirements.

Key Features

• Bi-metal construction: high speed steel teeth on alloy steel back for edge retention and flex resistance
• 18 TPI constant pitch with wavy set for smooth cuts on thin-wall and small-section material
• 100-foot coil allows custom blade lengths to be cut for a wide range of band saw machines
• Straight tooth rake angle and straight tooth form for consistent, controlled cutting
• Supports contour cutting applications
• 0.025 inch blade thickness balances kerf width with blade stiffness

Compatibility

Designed as a general-purpose bi-metal band saw blade coil stock suitable for cutting to length and welding into blades for vertical or horizontal band saw machines that accept 0.5 inch wide blades.

Installation Notes

Cutting and welding blade coil stock to length should be performed by a qualified technician using a blade welder and appropriate personal protective equipment including cut-resistant gloves. Ensure the band saw is fully powered down and unplugged before installing any blade. Follow the band saw manufacturer guidelines for blade tension, tracking adjustment, and blade guide clearance. Blade welding and annealing procedures should conform to the coil manufacturer recommendations to avoid stress fractures at the weld joint.
