oil;
2. When installing and removing the handle by hand, after the
handle is removed, it is a good habit to apply anti-rust oil before
installation;
3. Regularly measure the concentration of coolant to prevent the
decrease of the concentration of the coolant, and the bacteria

According to incomplete statistics, the service life of the tool
holder is often 5-8 years. BT30 TOOL HOLDER,ER collet chuck, The
tool holder is mostly calculated by the factory as an approximate
fixed asset. The ratio of the consumption capital of the tool
holder used in the factory to the consumption of cutting tools is
approximately 2:8. Therefore, the choice of high-quality,
easy-to-use tool holders, although the initial investment is
slightly increased, but it can save considerable expenditure on
cutting tool consumption in the future, supplemented by effective
protective methods, will make the boss assured, let employees use
