The 3690-23RSPro Stihl Rapid Super Pro saw chain is a new high-performance full chisel chain designed for professional users who need maximum cutting speed and efficiency. Its narrow kerf design reduces the amount of wood removed during the cut, allowing up to 20% greater cutting performance compared to previous .325" chains.

With a .325" pitch and .050" (1.3mm) gauge, the 3690-23RSPro delivers extremely high cutting and boring performance with excellent cut quality, low chatter and reduced vibration. It is ideal for felling, delimbing, firewood cutting and maintaining young stands, making it a strong choice for modern professional saws such as the MS 261.
