Starrett 21571 Welded Bandsaw Blade 12 Ft Bi-metal M42

Product Description

The STARRETT 21571 is a welded bi-metal bandsaw blade designed for demanding metal-cutting applications in industrial and fabrication environments. Built on the Intenss PRO-VTH platform, it combines a flexible alloy steel back with M42 high speed steel teeth for extended blade life and consistent cut quality. The blade measures 12 feet in length, 1 inch wide, and 0.035 inches thick, with a variable pitch of 3 to 4 TPI. Ground teeth with a positive rake angle and raker tooth set promote aggressive, accurate cuts through solid stock. Licensed contractors, fabricators, and maintenance machinists are the primary installers of this blade type.

The STARRETT 21571 is suited for contour cutting and straight cutting operations on steel and exotic steel materials. Variable pitch reduces harmonic vibration during the cut, which extends blade life and improves surface finish on difficult alloys. It is appropriate for use in both production shop environments and job-site metal fabrication settings where consistent throughput on hard ferrous materials is required. The 12-foot welded loop format fits a range of vertical and horizontal bandsaw machines that accept 1-inch wide blades.

Key Features

Compatibility

Designed to fit vertical and horizontal bandsaws that accept a 1-inch wide, 12-foot blade with 0.035-inch thickness. Confirm machine wheel diameter and blade guide clearance before installation.

Installation Notes

Blade installation should be performed by a qualified machinist or maintenance technician familiar with bandsaw equipment. Power down and lock out the machine before removing the old blade or fitting the new one. Verify blade tension and tracking adjustment according to the saw manufacturer's specifications before resuming operation. Wear cut-resistant gloves when handling coiled or uncoiled bandsaw blades.
