The drilling machine is a machine tool which mainly uses a drill to machine a hole on a workpiece. The drilling machine is simple in structure, relatively low in machining precision, capable of drilling through holes and blind holes, replacing special cutters, and capable of expanding, reaming or tapping and the like. For some parts to be tapped, a drill bit is usually used for drilling, and a tap is used for tapping in the drilled hole in a machine. Drilling a hole in the sheet requires a reduction in the feed and force to drill the hole through slowly or the drill bit is broken. Tapping with a drill press requires a feed amount that is adapted to the pitch of the hole or otherwise breaks the tap.
In order to improve the processing efficiency, manufacturers of drill bits produce drill and tapping integrated drill bits, but the use of the drill bits has higher requirements on the experience of operators, and the use effect on pistol drills is better. Because the main shaft box of the bench drill can not change the speed at any time, the belt wheel of the belt needs to be changed during speed change, time and labor are wasted, the speed change range is small, feeding is also manual, and the drilling and tapping integrated drill bit is difficult to use on the bench drill.
