Industrial Keyless Drill Chucks

Keyless Drill Chucks mean the Drill Chucks tightened by hands without Chuck Key, and, are also called “Keyless Chucks” 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.

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.

Industrial Keyless Drill Chucks

  • The super precision class (Gold) gives the world highest accuracy and quality. Run-out Accuracy (T.I.R) is less than 0.0012 inch.
  • Highest Precision (Silver) also belongs to a high precision class chuck and is able to have a long durable accuracy as well. The Run-out Accuracy (T.I.R) is less than 0.0020 inch.
  • Parts are processed proper heat treatment and annealing and have a long life with precision.
  • The Jacobs Taper is finished by grinding after being heat treated. Therefore, the taper hole has a good fitting to the spindle of the machine and to the arbor.
  • Many steel balls are contained inside the chuck, which enables and easy and fast gripping or releasing of the tool.
  • Its self - tightening structure will increase the cutting power and also the gripping torque.
