Tsumura FV4 Sprocket Nose Chainsaw Bar
3/8" Pitch .058" Gauge Bar for Jonsered
The Tsumura FV4 is made from the finest quality, high-carbon tool steel. Sprocket Tips feature large-diameter sprockets encased by heat-treated carbon steel. Solid one-piece milled high-carbon steel bar that has a brushed steel finish. Rails are precision-ground to uniform tolerance. Longer tip reduces chain "hammering" of bar rails for longer bar life.
The TsuMura Pro "FV" tip has been engineered to provide long service life, with a thick sprocket and strong cogs that stand up to hard use and extreme temperatures. The sprocket tip is firmly held by three rivets and is recessed into the bar body for excellent stability and accurate chain feeding.
