Setting the Industry Standard for Innovative Toolholding

In every industry, with any type of material, part and quantity, REGO-FIX gives you the unmatched reliability you need for success. Our carefully matched systems provide optimal fit and accuracy to minimize vibration and tool runout while they maximize clamping force, toolholding security, tool life and output quality.

REGO-FIX introduced the first ER collet chuck in 1972, and it became the enduring industry standard. Today, our innovative solutions make it easy to achieve excellent surface finishes and consistent job results in a wide variety of machining applications. For the toolholding innovations you need to produce precise results every time, look to REGO-FIX.


The industry-standard toolholding solution for all shank types, materials and tool types – from the company that pioneered it.


The ultimate in secure toolholding and excellent vibration damping supports high-speed milling and drilling.

Multi Line

A toolholding system for traditional machining applications, with reduction sleeves for efficient through coolant in a self-sealing system suited to most hydraulic expansion chucks.
