18HX – Harvester Saw Chain Micro Chisel® – .404":

• Features Micro Chisel cutters with small-radius working corners for excellent performance and ease of maintenance.
• Uses patented saw chain steel for greater durability, especially in cold cutting conditions.
• Blued cutters offer superior corrosion resistance and improved strength.
• Wider, tougher coined drive links are thicker above the groove for increased strength.
• Larger rivets are used for reduced saw chain stretch.
