What is a Flat drill?

A flat drill is a type of drill that is one of the cutting tools. It is a type of drill that has a flat tip, that is, a flat shape, which is different in shape from the normal drill used for drilling. It is used for drilling holes on slopes and curves that are difficult to drill with ordinary drills, counterbore machining, and drilling intersecting holes. In addition, the flat drill is suitable for through holes in thin steel plates because it is difficult for burrs to form on the end side of the machined hole, the hole is less likely to bend, and a straight hole can be drilled flat.

Application of Flat drill

If you try to make a hole perpendicular to the slope with a normal drill, the drill will go along the slope or curved surface, so you will escape from the place where you want to make a hole, and at the end it will break. I will. The same is true if the exit is sloping, and you cannot make a straight hole. On the other hand, a flat drill can make a hole even on an inclined surface, or make a flat surface by counterbore processing to make a guide when drilling a deep hole. Of course, it can be used for R-shaped surfaces and intersecting holes, and can be flexibly drilled for various shapes.
