[Extended Lifespan and Efficiency] Carbide chains have a considerably longer service life compared to standard chains, last up to 10-12 times longer, resulting in reduced operational time and chain replacement costs. [Stronger Security] Low kickback design, more robust material than standard steel and harden rivets for stronger connection reduce the risk of chain breakage and minimizes the risk of accidents. [Increased Hardness] High hardness carbide cutter head and Japenese chrome-plated lead to effective resistance to wear from sawdust and sand, ensuring smooth operation in demanding conditions. For sharpening carbide-tipped cutters, use only diamond sharpeners in 11/64''(4.5mm) sizes.
