The rugged STIHL Carving E guide bar is precision crafted from three pieces of high quality steel and engineered for dependable performance. Each piece is stamped for consistent quality before being welded together for durability and induction-heat treated to provide high wear resistance. The nose of the bar is further strengthened by using a very hard steel alloy that is laser welded in place. Available in 10" and 12” length with a solid nose, this unique bar can only be used with ¼” and ¼” STIHL PICCO™ saw chains.
