Specialized Products, Technologies and Services

Collet Chucks

With a focus on made-to-order, our products are manufactured under thorough safety and quality management and in consideration of how they will be used.
We offer collet chucks with minimal deflection. We also provide suggestions for making improvements to any problems with collet chucks already in use.


Installed in internal grinder grinding wheel spindles, our quills make use of our core precision collet chuck technology and are able
to support the full spectrum of product commercialization, as well as to reduce points to miniscule diameters, thinning the external
diameters of internal screws, increasing deflection precision when working with very small diameter long holes, and working with high
damping materials. We manufacture high rigidity quills to order, including steel quills, carbide-brazed quills, and carbide solid quills.
