Starrett 21558 Bi-metal Bandsaw Blade 15 Ft 3-4 Tpi

Product Description

The STARRETT 21558 is a welded bi-metal bandsaw blade from the Intenss PRO-VTH series, built for demanding metal-cutting applications in fabrication and maintenance shops. It measures 15 feet in length and 1-1/4 inches wide with a 0.042-inch blade thickness. The cutting teeth are M42 high speed steel with a positive rake angle and ground cutting edge, delivering clean, consistent cuts through steel and exotic steel alloys. Variable pitch tooth spacing in the 3 to 4 TPI range reduces vibration and harmonic chatter during the cut, extending blade life and improving surface finish on structural steel and heavy-wall tubing.

This blade is intended for contour cutting and straight-section work on ferrous metals including carbon steel, alloy steel, and exotic steel materials. It is suited for installation on horizontal and vertical metal-cutting bandsaws in industrial, mechanical, and trade shop environments. Licensed machinists, pipefitters, ironworkers, and maintenance mechanics typically work with blades in this size class. The raker tooth set and flexible back design allow the blade to track smoothly on standard bandsaw wheel configurations without premature back fatigue.

Key Features

• M42 high speed steel teeth with ground cutting edge for long tooth life on hard metals
• Variable pitch 3 to 4 TPI reduces vibration and chatter during cutting
• Positive rake angle improves chip clearance and cutting speed on steel
• Raker tooth set provides consistent chip flow in ferrous metal applications
• Flexible back construction supports tracking on standard bandsaw wheel diameters
• Rated for contour cutting as well as straight cuts in steel and exotic steel alloys

Compatibility

Designed for metal-cutting bandsaw machines accepting a 15-foot, 1-1/4-inch-wide blade. Suitable for ferrous material applications including steel and exotic steel alloys as specified by the manufacturer.

Installation Notes

Bandsaw blade installation should be performed by a qualified technician with the machine fully de-energized and locked out per OSHA lockout/tagout requirements. Always verify blade tension and tracking alignment before resuming operation. Use appropriate blade guides rated for the blade width and thickness. Handle the coiled blade with cut-resistant gloves, as the M42 tooth tips are extremely sharp.
