Abstract

The article of this design is a drill used in a cutting and drilling tool. The drill has multiple rectangular pillars, so the connecting parts of the drill are in contact with each other, maintaining excellent roundness and hole diameter accuracy. Furthermore, the drill has a pagoda shape, making it less likely to break at the connecting parts of each part, reducing the load on the cutting blade, and providing high hardness, excellent wear resistance, and a long lifespan.
