Starrett 16890 Welded Bandsaw Blade Bi-metal Variable Pitch

Product Description

The STARRETT 16890 is a welded bi-metal bandsaw blade engineered for continuous cutting of structural steel and other demanding ferrous materials. Built on the Versatix MP platform, it pairs a flexible steel back with M42 high speed steel teeth for extended blade life under variable load conditions. The blade measures 14 feet 4 inches in length, 1 inch in width, and 0.035 inches in thickness. Its variable pitch tooth pattern at 10 to 14 TPI reduces harmonic vibration and minimizes tooth strippage when transitioning through varying cross-sections. A raker tooth set and positive rake angle combine to promote efficient chip clearance and consistent cut quality across a range of structural profiles.

This blade is suited for professional metal-cutting bandsaws used in fabrication shops, structural steel work, and mechanical contracting environments. The variable pitch design performs well on solid bar stock, tube, and structural shapes where interrupted cuts and changing wall thicknesses are common. A licensed metalworking technician or fabricator typically handles installation and blade tensioning on industrial bandsaw equipment.

Key Features

• Bi-metal construction with M42 high speed steel teeth for extended service life on structural steel
• Variable pitch at 10 to 14 TPI reduces vibration and tooth strippage on varying cross-sections
• Raker tooth set with positive rake angle promotes efficient chip evacuation
• Flexible back material accommodates continuous bandsaw operation and wheel flex
• Welded construction provides a seamless, balanced loop for smooth blade tracking
• Versatix MP series rated for structural steel applications

Compatibility

Designed as an OEM-style replacement or aftermarket blade for industrial metal-cutting bandsaw machines accepting a 14 foot 4 inch blade loop with a 1 inch width and 0.035 inch kerf thickness.

Installation Notes

Installation should be performed by a qualified machinist or fabricator familiar with industrial bandsaw equipment. Power down and lock out the bandsaw before removing the worn blade or installing the new one. Verify wheel guides, blade tension, and tracking alignment per the saw manufacturer specifications before resuming cutting operations. Confirm blade direction of travel so teeth face the correct cutting direction before powering the machine.
