Do you know how hot a deep hole drill can get when working at high speed? 

It could literally fry an egg! But since the oil cooler, everything has changed.

It is just like a sweet little coat, cooling down the deep hole drill and keeping it in good condition.

Workers said that since using Dongxu oil cooler, the working efficiency of deep hole drilling has been improved a lot, and the precision has also been improved.

This is the legendary "twice the result with half the effort"!

Friends, the development of science and technology really changes life! Even deep hole drilling has such a high-level "bodyguard". Next time I have the opportunity, I also have to go to feel the cooling effect in the end how good!
