Starrett 40075 Hss Power Hacksaw Blade 21 Inches 4 Tpi

Product Description

The STARRETT 40075 is a fully hardened molybdenum high speed steel (HSS) power hacksaw blade built for demanding cutting applications in professional trade environments. Measuring 21 inches in length with a blade thickness of 0.088 inches and a tooth pitch of 4 teeth per inch (TPI), this Redstripe blade is engineered to handle heavy feed pressures without premature wear. It is designed for use in power hacksaw machines and is suited for machinists, fabricators, and industrial maintenance technicians who need consistent performance across a broad range of metal stock.

This blade performs well across a wide variety of metal materials, including stainless steel and other tough-to-cut alloy steels that would wear out lesser blades prematurely. The 4 TPI configuration makes it well suited for cutting larger cross-sections of stock material. It is a common choice for job shops, maintenance facilities, and fabrication shops where power hacksaws are used to break down bar stock, structural sections, and solid billets.
