What To Consider When Buying?

Any kind of mitre saw is an investment. However, it is important to keep an eye out for an array of features that will vary depending on the make of the saw as well as what type of saw it is. For new craftsmen who want to learn a new skill, it is vital that you pick out a saw that is compatible to the skill you are learning but also has the right features for you to advance. For already trained peronalel who have honed their craft, it is important that you keep in mind all of these factors in order to produce professional quality work. Here is a list of characteristics we recommend bearing in mind when planning to buy a compound sliding mitre saw:

  • Dust collection - This feature is usually initially ignored when buyers plan on buying a mitre saw. This is a common mistake and they then tend to complain about the amount of dust that builds up while cutting. For the most part, you will not be using your saw outside which means that the dust will tend to clog up the room you are working in which can cause a dangerous working environment and the possibility of dust getting into your eyes. It is crucial that you look for what measures have been taken to reduce dust build-up when using the saw
  • Blades -  There are 3 typical blade sized: 8", 10" and 12". The choice of blade size determines the maximum depth of cut. There is no use in buying a mitre saw with an 8" blade if you desire a deeper, more versatile cut. It is also important to note the number of teeth the blade as this will affect the quality of the cut.
  • Safety features - As when using any type of power tool, safety is paramount. You need to check what precautions have been taken to make the saw safe to use and if you are qualified to use the saw. Even professional carpenters with many years of experience will have accidents with a hazardous saw.
  • The build and finish - Most mitre saws are made using aluminium or steel with guards, handel and leavers etc being made from long-lasting, enduring plastic. Manufacturers will try to save money by using cheap materials to build their saws, but this will only make you pay out for another product once it breaks. Most well known and establish brands, such as Dewalt, will invest in sturdier products to maximise safety and efficiency. The best way to avoid a poorly built mitre saw is to go to a store with some saws on display so you can clearly see what brand of saw you feel will be better lasting
  • Lasers - This is a common method used by brands to ensure accurate cuts. However, some brands do cut corners which means that their lasers are either off centre or are too weak to be useful
