The Industry’s Best End Mill Holders
When you need to drill out parts, holding your tools in place is crucial to the success of your operation. With that in mind, we strive to deliver the industry-best fit and accuracy in our end mill holders to ensure you get the desired results.

Centaur toolholders offer fully ground flanges and V-grooves, ensuring your operation enjoys smooth, accurate handling in automatic tool changers. You’ll also experience reduced vibration at high RPM because our end mill holders are balanced for 22,000 RPM and concentric to 0.0002 TIR or better with the AT3 fit.

We offer end mill holders in a variety of metric and inch sizes, with stub, standard, and extended lengths. Centaur produces end mill holders with the CAT40 and CAT50 taper to allow insertion directly into the machine spindle for a secure drill hold. We also make BT30, BT40, and BT50, or externally sealed coolant through varieties.

The Centaur “Green Zone” ensures accurate results
At Centaur Precision Tools Inc., all our end mill holders and other tools are created with our proprietary “Green Zone” design. We use exacting specifications to ensure you receive full-radius contact to hold tools where you need them, delivering premier precision performance.

“We understand how much the quality and accuracy of your end product matters to you, and so our manufacturing process passes rigid quality checks through high precision gauges,” Centaur’s founders said. “The Centaur Green Zone centralizes the cutting tool, providing concentricity that can increase tool life, enhance RPM and feed rates, and improve workpiece accuracy and finish.”
