The operation of FC-32A is particularly simple and does not require special technology, even the apprentice can grind out an accurate drill.

The design focuses on the practicality and using efficiency. The drills with different sizes and shapes can be set completely within a few seconds. When the drills are grinded, the chuck will execute rotation motion, front and rear motions, and the entire working head will swing around, and three actions are carried out simultaneously, so that the correct arc can be made by grinding, and the rear bevel size of the drill can be adjusted arbitrarily.
