ER

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

powRgrip

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.

micRun

System TIR of < 3 μm at 3 diameters with a grooveless clamping nut for silent operation and low vibration.

ER Lathe/Swiss

ER and ER UP (Ultra Precision) vibration-damped collets with a 16-slot design for a wide clamping range with low TIR and up to 20% more clamping length on small diameters.

Measuring Technology

The REGO-FIX 3D-EdgeMaster precision centering device is the first in our newly launched metrology product line with more innovations to come.

REGO-FIX Myth Buster: All Toolholders Are Manufactured to the Same Quality Standards

Most toolholders appear nearly identical on paper in terms of their materials, geometries, and tolerance claims. In real-world machining environments, however, the truth comes out, and those similarities quickly disappear.  The truth is simple: not all toolholders are...

What It Is and Why It Matters: Vibration Monitoring and Smart Toolholders

In our first blog for our “What It Is and Why It Matters” series, we went over the fundamentals of total indicator runout (TIR), vibration damping and concentricity, which are three essential factors that define machining precision. For our second installment, we took...

Three Things to Know Before Selecting a Toolholding System for High-Speed Machining

High-speed and multi-axis machining continue to reshape modern manufacturing, driving shops to seek greater precision, faster cycle times and tighter tolerances. But delivering consistent performance at elevated speeds is about more than spindle power and advanced CAM...

REGO-FIX Myth Buster: Tool Balancing Only Matters at Exceptionally High RPMs

It’s a common assumption in many machine shops that balancing only matters when spinning at extreme spindle speeds. That assumption overlooks a simple but critical fact: Imbalance affects cutting performance even at typical, everyday machining speeds. At REGO-FIX, we...

What It Is and Why It Matters: Clamping Force and Torque Transfer

In our first blog for our “What It Is and Why It Matters” series, we explored the fundamentals of total indicator runout (TIR), vibration damping, and concentricity, which are three essential factors that define machining precision. For our second installment, we take...
