The cutting tool that need to be sharpened: reamer

Reamer is also a cutting tool that often needs to be sharpened. Its grinding method is relatively simple. Because of the higher requirement for the reamer precision, can be repaired 2-5 times generally. Before grinding the reamer, it is necessary to detect the diameter of the cutter. If the diameter is not within the required range, it can be repaired no longer. After grinding, the coating of the reamer has no coating.

Drill Bit

The drill bit is the best cutting tool for grinding.
The design should consider the need for grinding.
For preprocessing or general hole accuracy, degree of the drill bit grinding is worn at most 20 times. For high precision drilling bit, it can be sharpened 5 times.
