The Use of Inadequate Blade Can Lead to Table Saw Kickback
Table saw kick is dangerous and quite powerful presenting a considerable risk for any crafter. Kickback, caused by the biting of the blade of a section of a workpiece, flings out a workpiece out of a table saw hitting the operator. As this occurs with a considerable speed, kickback is damaging and dreaded, but which, with some caution and know-how can be prevented.
To start with, table saw kickback is the result of some errors or defects of one of the several aspects of table sawing. In most cases, however, it is caused by the use of an inadequate saw blade. Such blades are warped, dirty, dull, broken, too small, bent, too fine or in some way not perfectly suitable for the performed operation. These faults of the blade can easily cause a nasty kickback. Follow a couple of simple guidelines and common sense with the blade usage and you should not have any table saw kickback as a result of bad blade usage.
Whenever you decide to use broken, dull, dirty, bent, and warped or with some other defect, a bigger contact will be generated between the blade and the stock. Thus, the cut will lead to more heat and friction, increasing thus the chances of a kickback. When there is greater contact between the workpiece and the blade, there are higher chances of a table saw kickback.
The likelihood of a kickback is also higher is you are using a blade that was not meant for the performed application. A table saw kickback is almost unavoidable if the blade in use is too fine or too small.
More specifically, when a blade fails to reach between 1 and 1.5 inches above the stock that needs to be cut, it is a too small blade for the operation. As a large number of teeth will be at the same time within the workpiece, it will force each tooth to get through an extra amount of material prior of leaving the stock. The greater contact between the stock and the blade leads to increased stress, friction and heat and eventually to greater likelihood of a kickback.
When a blade is too fine or when the width of the blade is insufficient for the stock in question, there will not be enough downward pressure on the stock, enabling it to rise and kickback from the table. Thus, it is of outmost importance for the blades used on the table saw to be straight, sharp and clean at all times, ensuring the safety of you and the work environment.
