    2. When drilling, the chips can be separated freely and discharged out of the hole in time as they are formed;

    3. It can be grinded many times conveniently, and the angle value and main dimension parameters of the cutting part after grinding are unchanged;

    4. Maximum productivity and good processing quality.

    The structure of drill bit depends on its working conditions: relative to the drilling direction of fiber, drilling diameter, drilling depth, and required machining accuracy and productivity. The following common structures of extra-long wood drill bit are mainly introduced.
