Instructions:

• Before installing the end mill bits, you should first use the cleaning fluid to clean the end mill bits holder and the holder hole, dry them and then install.
• When the diameter of the end mill bits comes longer, in order to avoid the accidental removal of the end mill bits, it should be used with a flat cut notched handle and the corresponding side locking way to install.
• If the tool holder is used for a very long time, it will easily cause end mill bits to break off from the tool holder. In this case, replace the new tool holder.

Notes:

• Stop immediately in the processing of anomalies when using the end mill bits and find out the reason before processing;
• Pay attention to the condition of wear and tear of the cutting edge and timely repair the end mill bits;
• Cleaning the end mill bits and use oil after using, keep end mill bits properly.
