As well as spool and lines we can also supply you with complete Bosch grass strimmer spool head assembly units should you need to replace the entire unit. If the area being strimmed should become more difficult with the presence of heavy brush such as woody growth consisting of shrubs and young saplings then I would fit the saw toothed type blade. The sawing action will eat its way through this material providing of course the blade is sharp. Selection of Strimmer Blades

Blades are designed to do specific tasks. Unlike the nylon line you may be more familiar with using, these solid blades should never be used for the more normal grass trimming tasks. And certainly never used up against walls or trees. My Preferred Method Brambles and Heavy Brush It's important to regularly replace worn out or damaged parts on your strimmer to ensure that it continues to work efficiently, and see you are getting the best cutting results while being certain that your strimmer is working safely. Good maintenance of your strimmer will help to prolong its life and our range of Bosch strimmer parts are genuine spares which are low cost, easy to fit and hard wearing. You will need to choose blades that will be suitable for your particular machine as there are differences. Stihl replacement blades are very different from those used on Bosch trimmers. Even Bosch have different blades for their ART 23-18 LI grass strimmer’s from their ART26LI and ART26 Accutrim models. For an example take a look at the Art 23 versions here. The ART 23-18 LI Plastic Blades As you might imagine, it would need to be a more powerful type of strimmer to drive a metal blade and at a speed fast enough to cut through the type of growth mentioned above. That power could only be supplied by a petrol powered strimmer. These machines will work away for hours day after day no problem.

Personally I prefer to use my heavy gauge nylon line on as many of these tough jobs as much as possible before moving up to the metal blades. Even then, this will be done in stages if I had some difficult cutting to do. Metal blades come in a variety of shapes. The most common are the 3 arm versions and the multi-teeth type which resemble a circular saw. See a popular example here which is the Silverline 675319 strimmer blade.
