Features
The 9/16" x 8" Cold Chisel is expertly designed for cutting and shearing cold metals with precision and durability. Its hand-ground, sharpened edge ensures clean, accurate cuts, making it ideal for separating workpieces and assemblies such as rivets, screws, and welding joints. The octagonal handle design provides a secure, comfortable grip and prevents the tool from rolling on flat surfaces, enhancing safety and control during use. The striking head is turned and chamfered for improved impact resistance, while the core material design prevents mushrooming, ensuring long-lasting performance. Tempered to a hardness of 54–58 HRC along its entire length and forged from premium hardened chrome vanadium steel, this chisel combines strength, balance, and reliability. Proudly crafted by RENNSTEIG, a member of the KNIPEX Group, this tool embodies German engineering excellence and precision in professional-grade metalworking tools.
