Choosing Your Circular Saw Blade Posted on 01 May 11:35 , 0 comments
When considering any composite decking project it is highly likely that you are going to have to make some adjustments to your lengths of board. We know that there are literally thousands of tools out there so we thought we would help you understand how to choose the right saw blade for cutting our products. This blog post will break down the various attributes for the appropriate saw-blade and why we recommend them for your fine cuts.
The EnviroBuild installation manual advises the use of a circular saw using a 40 tooth alternate top bevel finish blade. The amount of teeth on the blade is important to the speed and accuracy of the cut. A blade with a lower tooth count will cut faster but with a rougher finish. Alternatively, the higher the tooth-count on the blade the slower the cut but the more accurate it will be. With this in mind, if you choose a blade with a tooth count that is too high then you run the risk of the cut being to slow and burning the material you are cutting. This may be problematical with composite materials with a high level of plastic. EnviroBuild recommend the 40 tooth blade as it is quick enough to not burn the material yet it has enough to make accurate cuts.
The alternate top bevel finish blade refers to the tooth configuration on the blade. In this instance this specific configuration makes the angle of the teeth useful for cutting material like our composite boards, natural wood or veneered plywood.
Most of the major manufacturers will make what appears to be a similar blade, but the price will range from a few pounds up to just under £100 in the same way that the quality will differ. The design, amount or carbide and the quality of carbide used in the blade is what primarily influences the cost.
EnviroBuild recommends going for one of the more well-known makes such as DeWalt, Bosch or Titan as the blades tend to keep it’s sharpness for a longer period hopefully ensuring that you will only require 1 or 2 blades for your project (depending on project size).
