Tsumura Lightweight Guide Bar, FK Series - D025 Style - 3/8" Pitch / .063" Gauge (D025 - Stihl Large Mount)

Tsumura chainsaw bars are manufactured and assembled in Japan on advanced technology machines and equipment to provide a high standard of durability, strength, finish, and accuracy in the heat treatment process. Tsumura chainsaw guide bars also incorporate uniform groove gauge tolerances for a precise chain fit and improved cutting stability over the bar nose. The sprocket noses are made of quality material and carefully heat treated and the roller bearings are the best available. Even the rivets were studied to determine the strongest and most compatible material specifications. Our bars are sold to all markets throughout the world and are the choice of professional loggers everywhere.

Tsumuraʼs chain saw guide bars incorporate a unique design that makes the lightest guide bars available today. Dove-tailed notches are staggered and cut into the bar surface and packed with hard resin which reduces the weight of the guide bar by about 20%. This is improves cutting efficiency and stability and also reduces user fatigue. In keeping pace with the progress in the technology.
