Using the right line can save you time and money
The type of trimmer line you choose can greatly impact your cutting performance. That's why STIHL manufactures six models of trimmer line - bringing together quality materials and manufacturing for superior cutting. Why six models? Because not all cutting jobs are the same - we make different diameters and shapes of cutting line to accommodate the wide range of cutting scenarios you might find in your landscape.Diameter
The diameter of your trimmer line will impact both its cutting precision and durability. Not all diameters are approved for all STIHL trimmers - please refer to your instruction manual to see what diameters of trimmer line are approved for your model of STIHL trimmer.Shape
The shape of your trimmer line will impact how your trimmer cuts through weeds, as well as its durability. Round trimmer line is the most common shape. Round line cuts well and holds up well against abrasion. It is also easier to spool and feed through a trimmer head. Non-round trimmer line comes in a variety of shapes. These shapes have hard edges that slice through vegetation cleaner than round trimmer line (which can "tear" weeds after it begins to fray). These hard edges, however, make the trimmer line less flexible, which can reduce its durability against abrasion.STIHL Trimmer Line
There's high-performance STIHL trimmer line for every operating condition. STIHL manufactures trimmer line using a custom blend of polymers to produce a line with the best all-around characteristics of abrasion resistance, flexibility over time and temperature ranges, and welding resistance. Here are the models we offer:Premium Round Line
