The movement mode of the impact drill adds the impact function to the movement mode of the electric drill. Relying on the high frequency and low Joule per minute impact and the original drilling mode, a single impact and drilling can remove more machining residuals. Quantify the effect, thereby improving work efficiency. And this is DEWALT model , and 13mm(1/2 inch) also.

Product Specification

The percussion drill is only in the impact gear when drilling the wall, and all other times use the electric drill gear. The percussion drill can drill ceramic tiles. The specific operations are as follows:

Method 1: When drilling ceramic tiles with an impact drill, start at a slow speed and increase slowly so that the tiles will not crack.

Method 2: If you are a novice who is afraid of cracking the tiles, you can use ceramic drills to drill the tiles. The corners of the tiles are the easiest to crack. At this time, you can use a glass drill to penetrate the tiles (you must add water when using a glass drill), and then use an impact drill to drill into the concrete. When drilling holes, you must pay attention to the direction of rotation of the drill chuck. Turning to the right is a forward rotation. The drilling must be forward rotation. Otherwise, the reverse rotation will not only fail to enter, and it will be easier to break the drill.
