Chucks Ever Evolving Capabilities
For over seven decades, companies in industries like agriculture, earth moving, and mining, as well as major automotive companies and automotive tier-one suppliers, have trusted Drewco to design and build the chucks that hold their parts.
Unlike other chuck providers, where custom chucks are a small part of their off-the-shelf businesses, we clean sheet our chuck designs to your workpiece and production requirements. They can be mounted vertically, horizontally, or inverted. Activation methods include manual, mechanical, pneumatic, and hydraulic.
We design to:

Advantages of Collet Chucks
A collet chuck’s advantage over other chucking systems is that it combines the following desirable traits into one chuck for repeatable part production:
The solid expansion sleeve design of Drewco hydraulic chucks offer greater grip force and accuracy than other styles of chucks. Our hydraulic chucks are often used in high-precision machining like grinding or used in confined areas where manual closure would be difficult.
Diaphragm chucks provide significant clamping force and accuracy by forcing a diaphragm open, inserting a part, and allowing the diaphragm to close. A variety of jaws and cages can be designed to accommodate a significant range of part sizes.
Drewco makes eccentric chucks meant for applications with off-center turning. These chucks have a variable axis setting capacity and allow for irregular turning with highly accurate incremental adjustments.
Special Use Chucks
Custom special use chucks can be designed with less limitations and faster changeover for special-purpose chucking such as smaller bars, surface irregularities, or the need to swivel or equalize a part.
