| Circular saws come in a few different sizes which are normally based on the diameter of the saw blade. These can Range from 125mm (4-15/16”) up to 230mm (9-1/16”). They are rated by horsepower and/or RPMs of the saw blade. When choosing a circular saw take into consideration what you are going to use the saw for and how thick the timber or materials are that you wish to cut. |
Circulaw saws can cut to certain depths, depending on the size of the blade being used. Below is a list of common sizes and their respective depths:
125mm (4-15/16”) – 41.5mm (1-5/8”) 190mm ( 7-1/2”) - 60mm (2-3/8”) 230mm (9-1/16”) - 85mm (3-3/8”)
Generally speaking, the bigger the blade the deeper the cut you can make. However, it's good to remember that the larger units are also heavier. |
| Circular Saws have controls for adjusting the depth of the cut and the bevel of the cut (the saw blade can be beveled from zero to 45-degrees). These controls are generally easy to adjust and can be firmly tightened to hold the depth or angle. |
| Circular Saws all have some basic safety features. Most have a safety switch, which must be held before the trigger can be pressed i. There should also be a blade guard that moves easily when pushing the saw through wood or other materials, but springs back into place when the saw is clear of the cut, which is probably one of the most important features of all. Gloves and eye protection are highly recommended, as are dust masks and ear defenders. Circular saws can be very dangerous if not used properly and should always be treated with respect and care. |
