Tsumura Light Weight Guide Bar & Chain Combo – D025 Stihl 3/8″
A genuine Japanese Tsumura Light Weight guide bar matched with your choice of professional Carlton or Oregon chain — built for serious cutting performance in Australian hardwood.
The Tsumura Light Weight bar begins as a Light & Tough solid steel bar before undergoing precision machining. Staggered weight-reduction dove-tailed slots are cut into the bar body and filled with high-strength resin, reducing overall weight by approximately 20% while maintaining rigidity and rail durability.
Manufactured from a single piece of SKS-51 Japanese steel, this is a professional-grade guide bar designed for demanding farm, firewood and forestry applications.
✔ Why Choose This Combo
Lighter without compromise
Resin-filled weight-reduction slots deliver a noticeably better balance and reduced fatigue, while maintaining bar rigidity.
