Starrett 21562 Bi-metal Bandsaw Blade 186 in 3-4 Tpi

Product Description

The STARRETT 21562 is a bi-metal welded bandsaw blade from the Intenss PRO-VTH series, designed for demanding metal-cutting applications in fabrication and machine shop environments. The blade measures 186 inches long and 1-1/4 inches wide, with a thickness of 0.042 inches and a variable-pitch tooth pattern of 3 to 4 TPI. The M42 high speed steel tooth material provides heat and wear resistance during high-production cutting cycles. The ground cutting edge and positive rake angle support smooth, efficient stock removal. A raker tooth set and straight tooth form keep cuts tracking true through solid bar, structural sections, and exotic steel profiles. Licensed machinists and metal fabricators are the typical installers for blades at this spec level.

This blade is suited for horizontal and vertical bandsaw machines with a 15-foot 6-inch wheel-to-wheel blade path. It is intended for cutting carbon steel, alloy steel, and exotic steel including stainless and high-alloy grades. The flexible back type allows the blade to run continuously around bandsaw wheels without fatigue cracking under normal operating tensions. Contour cutting capability is supported by the 1-1/4 inch width, making this a production-grade choice for shops handling mixed material cuts across a range of cross-sections.

Key Features

• M42 high speed steel teeth for extended blade life in ferrous and exotic steel cutting
• Variable pitch 3 to 4 TPI reduces vibration and chatter across varying cross-sections
• Ground cutting edge for precise, consistent tooth geometry out of the box
• Positive rake angle improves chip evacuation and cut efficiency
• Raker tooth set and straight tooth form promote straight, accurate cuts
• Flexible back construction resists fatigue cracking under continuous bandsaw operation

Compatibility

Designed for bandsaw machines with a 186-inch blade path capacity accepting a 1-1/4 inch wide blade. Suitable for cutting steel and exotic steel materials per the Intenss PRO-VTH series application rating.

Installation Notes

Blade installation should be performed by a qualified machinist or maintenance technician with the bandsaw powered off and locked out per OSHA lockout/tagout procedures. Verify that the blade tension, wheel tracking, and guide bearing clearances are set according to the machine manufacturer specifications before operating. Wear cut-resistant gloves when handling bandsaw blades, as the toothed edge presents a laceration hazard. Do not exceed the blade speed rating of the saw or force the blade into a cut to avoid premature fatigue or blade breakage.
