Use Spotting and spotting drill bits are traditionally used to form a tapered hole for a lathe center to provide a starting point for a standard twist drill bit， designed to prevent the drill bit from running. Used for the production of center supports in components or parts requiring center to center machining. Note When using these drills， the temperature of the material (e.g. mild metal， mild steel， aluminum， acrylic plastic and wood， etc.) will be very high， add water or coolant to prevent the product produce smoke when using.
