Fein 21" 4 TPI High Speed Steel Power Hacksaw Blade 69908104002

Fein 21-Inch HSS Industrial Power Hacksaw Blade – 4 TPI This 21-inch High-Speed Steel (HSS) power hacksaw blade is a heavy-duty, high-performance cutting solution engineered for maximum versatility and industrial longevity. Designed to bridge the gap between metalworking and general fabrication, it features precision-ground teeth optimized for aggressive material removal across steel, wood, and polymers. The high-speed steel construction is specifically chosen for its exceptional thermal resistance, allowing the blade to maintain its hardness even under the intense friction of high-speed industrial applications. By delivering surgical accuracy and perfectly straight tracking, this blade minimizes material waste and significantly reduces secondary hand-finishing, making it an indispensable tool for high-volume fabrication shops, mechanical contractors, and professional machinists who demand clean, repeatable results.
