A circular saw is a power tool used for cutting materials such as wood, plastic and metal. It is called a circular saw because it cuts work pieces by turning a circular flat blade at high speeds. Though the circular saw blade is sometimes called a circular saw blade or circular saw grinding wheel, it is referred to as saw blade more often since a grinding wheel is more of the abrasive for polishing and grinding works instead of cutting. The circular saw grinding wheel can be made from different types of metal and the size of the disc varies too. The material, size and shape of the circular saw blade are chosen based on the end application, as in what material the blade is going to cut.
Besides the circular saw grinding wheel, the basic components of a circular saw includes a handle, a trigger or switch, an arbor nut, and a guard. The design of the handle of a circular saw is based on the configuration of the wheel and for what application the machine is used. The handle is important because it balances the tool and offers the best usability to the operator during an operation. The trigger controls the rotation of the blade. The tool turns when the trigger is pulled and it stops when the trigger is let go. The arbor nut is the circular saw grinding wheel holder. It clamps and secures the wheel in place. The guard is important and necessary for it protects the operator from touching the spinning blade.
The circular saw grinding wheels vary in size, cutting edge design, and material. The saw blades for cutting are mostly made of stainless steel or steel. Each of the saw blades is designed to cut particular materials and to work with specific types of power saws. Therefore, having the right blade is essential. Only with a right blade can the cutting work be done successfully. To choose the right blade for the application, the first thing to look for is the blade size.
The blade size refers to two specifications of the tool: the diameter of the blade and the diameter of the arbor hole. A circular saw grinding wheel is mounted onto the circular saw with the center hole. The hole has to fit to the size of the arbor nut so that the blade can be mounted onto the machine. The diameter of the blade has to do with the general design of the saw and the guard as well. Sometimes if the blade is too small, the cutting edge cannot reach out the guard and get contact with the work piece. On the other hand, it can be too big to fit into the guard as well. The other important specification of the blade is the cutting edge design.
A standard circular saw blade is the one an operator usually chooses for a general-purpose cutting operation. A standard circular saw grinding wheel always has teeth on the cutting edge. The number of teeth varies based on the applications. Generally speaking, the tooth number helps determine the turning speed, the application, and the finish of the cut. With fewer teeth, the blade cuts faster; yet, with more teeth, the saw is able to create a finer finish. In addition to the tooth number, the gaps between the teeth are also important. They are the gullets and the expansion slots.
Gullets of the blade refer to the tiny gaps between each tooth. The primary goal of the gullets is to remove the chips from the work pieces. Chips are the removed part of the workpiece. With larger gullets, the removal of chips can be done more efficiently and the feeding rate of the blade is higher. The expansion slots on the other hand refer to the deeper gaps that cut into the rim of the blade. The expansion slots are usually cut every 5 or 6 teeth. They help prevent the blade from warping during use. The warping of blade teeth happens when the blade repeatedly expands and contracts through the work piece.
