2-Finger Trigger Switch with Lock-Off Button

The current grinders you can access when you visit your nearest hardware shop have problems faced when handling them. The problem is that current grinders are quite difficult to activate and at the same time operate.

Most of the current grinders can be easily operated accidentally since they do not have a lock- off button.

Tool-free Guard

Another fundamental property or feature a customer should check in a grinder before buying one is the flexibility. Since you know that a grinder can be used for cutting and grinding applications, then it should be adjusted during any of the two applications.

Also, the tool should be used by different persons with different physical appearance; some may be tall or short. All these should be incorporated in the design of a grinder, and that is the flexibility.

The Tool free guard of Dewalt DCG412B 20V MAX* Lithium Ion 4-1/2" grinder allows for quick, easy guard adjustments/positioning, therefore very much flexible.
