When drilling a wall with electric drill ,workers usually require a depth gauge to calculate the depth of the hole . But our solution is simple. With the aid of the division length of the red line on the top of the drill itself,what the users have to do is just take a quick look at the scale of the red line to get a clear knowledge of the current hole depth without the usage of the gauge device at all .
