All of these options improve the durability of the light gauge nylon string, but if the vast majority of your trimming work centers on light grass clipping, you can probably get by with inexpensive nylon line. Some examples include reinforced composite nylon, internally reinforced nylon, and aluminum additives for added strength.Īlthough not line in the technical sense, some of the beefier string trimmers can work with nylon, or even metal, blades.
Manufacturers have come out with a variety of alternatives for heavier duty jobs, however. Nylon line is the most common line available, but it tends to wear out and break quickly on anything but lighter duty jobs. Trimmer line can be formulated to resist fraying and splitting or for durability, noise reduction, strength, and temperature resistance. Some shapes are only available in certain diameters. The shape of the line optimizes it for different applications. Check Out These Stihl Trimmer Line OptionsĪs an example of how the shape of trimmer line can vary-even from a single manufacturer, check out these options Stihl has for its customers: Premium Round Line Quiet Line Commercial Round Line Commercial Square Line Pentagon Line X-Line It has teeth, similar to a kitchen knife, and “saws” through heavier grass and weeds with relative ease. Serrated line is also an option when it comes to a sharper trimmer line.
The edges of these string trimmer lines are sharper than rounded trimmer line, and cut through the grass rather than tear at it. Some line comes in a square or star shape. Twisted line is a bit better, as the shape has a little more of a cutting edge to it. Rounded line is the most common type available, but it because it lacks a cutting edge, it rips the grass rather than cutting it. String trimmer line comes in a variety of shapes: round, twisted, square, star shaped, and serrated. The shape of the line also affects the cutting efficiency. Thicker line, however, requires more power to drive it at the same speed. A larger diameter line increases the power and durability of the line, which leads to less breakage and wear-out. This probably comes as no surprise to anyone, but the general rule with string trimmer line size is that the tougher the application, the thicker the line needs to be. With that said-which strong trimmer line size and type work best for which applications? Each string trimmer line size also comes in a variety of shapes, thicknesses, and materials. Thinner spooled line, thicker pre-cut line, serrated and square lines-even blades or chains could be used if you have a strong enough system.
