Starrett 20698 Welded Bandsaw Blade 5-8 Tpi Bi-metal

Product Description

The STARRETT 20698 is a welded bi-metal bandsaw blade from the Intenss PRO series, designed for demanding metal-cutting applications in professional shop and industrial environments. The blade measures 13 feet 4 inches in length, 1 inch in width, and 0.035 inches in thickness, with a variable pitch of 5 to 8 teeth per inch. The bi-metal construction pairs a flexible alloy steel back with high speed steel teeth, providing durability against tooth strippage and back fatigue during extended cutting cycles. A positive rake angle and raker tooth set improve chip evacuation and cut efficiency on both ferrous and non-ferrous metals.

This blade is suited for horizontal and vertical bandsaw machines used in fabrication shops, maintenance facilities, and metal service centers. The variable pitch tooth pattern reduces harmonic vibration during the cut, making it effective on structural shapes, solid bar stock, tubing, and mixed-section cuts. It is appropriate for licensed machinists, welders, and trade professionals who require consistent performance on ferrous metals such as mild steel and stainless, as well as non-ferrous materials such as aluminum and copper alloys.

Key Features

• Bi-metal construction with high speed steel teeth for extended blade life on metal stock
• Variable pitch 5 to 8 TPI reduces vibration and improves surface finish on varied cross-sections
• Positive rake angle promotes aggressive, efficient chip removal
• Raker tooth set supports straight, consistent cuts in solid and structural material
• Flexible alloy steel back resists fatigue and cracking under continuous bandsaw tension
• Welded blade construction ensures a consistent, balanced loop for smooth tracking

Compatibility

Designed for bandsaw machines that accept a 13-foot 4-inch blade loop, 1 inch wide and 0.035 inches thick. Suitable for cutting ferrous metal and non-ferrous metal workpieces. Verify wheel diameter, blade guide clearance, and drive specifications on the host machine before installation.

Installation Notes

Bandsaw blade installation should be performed by a qualified machinist or maintenance technician with the machine fully de-energized and locked out per OSHA lockout/tagout procedures. Confirm blade tension and tracking alignment according to the bandsaw manufacturer's specifications before resuming operation. Blade guides and thrust bearings should be inspected and adjusted to match the 1-inch blade width. Always wear cut-resistant gloves when handling coiled or uncoiled bandsaw blades.
