A spot drill is a special type of drill bit typically used for machining thin materials such as sheets, plastics, and copper, which require high dimensions and have high surface roughness. Compared to ordinary drill bits, spot drills have the following advantages:
Lower cutting forces and cutting resistance, avoiding material deformation and surface burrs.
They can be used at low speeds, making them suitable for machining workpieces with high precision.
They are usually used with special fixtures to ensure machining accuracy and stability.
They have a longer lifespan and are less prone to wear and breakage.
