What is a Drill grinder?

A drill is a cutting tool that aims to drill holes in a workpiece, and by rotating the drill itself or the workpiece, it scrapes off contact points and cuts holes while discharging chips. A twisted drill with a twist is a common "drill". The structure is divided into a tip for cutting, a twisted lead for discharging chips, and a shank for attaching to the holder. The tip and lead are called the body, and the drill is divided into a "body" and a "shank". The drill will become dull as the cutting progresses. Therefore, the tip is polished so that it can be used again. A machine that grinds the tip of a drill in this way is called a drill grinder.
