Stihl PMX 3/8 .050 lo pro ripping chain. Regarded by many to be the best lo pro ripping chain. Expensive due to the time consuming and awkward method of sourcing. This is our favoured chain to go on the GB lo pro milling bars but you can also use this on other lo pro bars to mill down the grain of timber. Suggestion as always is buy a spare chain – have this to hand ready to fit and save yourself [and us!] the drama of ordering a chain late Thursday and asking if you will get it Friday!
