Description
Overview:
The Chain Sprocket 3/8'' Picco 7T is a genuine Stihl OEM drive component for pole pruners such as the HT 100 and HT 101. Made from durable steel, it transfers power from the machine to the chain with consistent engagement and minimal slippage. The 3/8 inch (9.53 mm) Picco pitch with 7 teeth is designed for low‐profile chains, supporting smooth running and clean cuts in overhead pruning. Replacing a worn sprocket helps maintain chain speed, reduces wear on the bar and chain, and keeps your tool working efficiently. Suitable for professional landscaping and arboriculture as well as domestic garden care, this sprocket is built for reliability and a long service life under regular use.
