Understanding Kickback
What is kickback?
Kickback is a potentially dangerous occurrence that can happen while using a table saw. It refers to a sudden and uncontrollable reaction of the workpiece being propelled back towards the operator. This can happen when the workpiece becomes jammed between the blade and the fence or when the teeth on the back of the blade catch the wood and throw it back forcefully. Kickback can occur with any type of table saw, making it crucial to understand its causes and potential dangers.
Causes of kickback
Kickback can be caused by a variety of factors, and being aware of these causes is essential to prevent accidents. One common cause of kickback is when the workpiece is improperly aligned with the fence. If the workpiece is not parallel to the blade or if it is angled and not held securely, it can bind against the blade and result in kickback. Another cause of kickback is using a dull blade. A dull blade can cause the wood to burn and create excessive friction, increasing the likelihood of kickback. Finally, kickback can also occur if the operator pushes the workpiece too quickly or forcefully through the blade, causing it to become unstable and prone to kickback.
Potential dangers of kickback
Kickback is not only dangerous but also poses a significant risk of injury. When a workpiece is forcefully ejected from the table saw, it can hit the operator or anyone nearby with immense force. This can result in severe cuts, bruises, or even more severe injuries. Additionally, the workpiece itself can become a projectile, potentially causing damage to the surrounding area or other objects. To avoid such risks, it is crucial to take the necessary precautions and understand how to prevent kickback while using a table saw.
