Summary: | To provide a tool which can maintain sharpness, and to provide a diameter adjustment method and a drill.SOLUTION: A drill 1 includes first to third radius parts 11 to 13 extending in a radial direction R with a rotation axis Ax set to the center and extending in directions different from each other when viewed from a direction along the rotation axis Ax. The first to third radius parts 11 to 13 include: abrasive grains for processing a workpiece; and holding materials which hold the abrasive grains.SELECTED DRAWING: Figure 2
【課題】切れ味を維持することができる工具、径調整方法及びドリルを提供する。【解決手段】ドリル1は、回転軸Axに沿う方向から見て、回転軸Axを中心に径方向Rに延び、互いに異なる方向に向けて延びる第1~第3半径部11~13を備える。第1~第3半径部11~13は、被加工物を加工するための複数の砥粒と、複数の砥粒を保持する保持材と、を備える。【選択図】図2 |
