Keyless Drill Chucks mean the Drill Chucks tightened by hands without Chuck Key, and, are also called gKeyless Chucksh simply. It is most useful as Quick Change Chuck on the drilling machines, etc. The greatest feature of our Keyless Drill Chucks (Keyless Chucks) is that the cutting tools can be changed quickly. And if the diameter of the cutting tool is changed, the accuracy is stable. Since the Keyless Drill Chucks are manufactured in high precision processing and have the sure self-tightening mechanism, in the clock wise direction rotation, the drill bit is gripped hard automatically by the self-tightening mechanism, without loosening. Yukiwa Keyless Drill Chucks have higher accuracy than the specified accuracy and have been favorably reviewed by the users for 40 years from the beginning of manufacturing. There are many models and sizes of Keyless Drill Chucks, the customer can be selected the best one for the machine and/or drill to be used.

Does not require Chuck Keys
With many thrust balls being contained inside, the chuck can be operated by hands easily without using any Chuck Keys or tools.
Efficient Automatic Clamping
Since the Keyless Drill Chucks are manufactured in high precision processing and have the sure self-tightening mechanism, the drill bit is gripped hard automatically by the self-tightening mechanism, without loosening. As the cutting torque become larger, the clamping force will be stronger.
Outstanding Durability
All the parts are precision-made and hardened enough, and, moreover, the outside is totally enclosed type, all of which ensuring an outstanding durability of the chuck.
