Description

This 100x77x53.5mm Zero Point Dovetail Holder is designed for precision CNC workholding applications where low-profile clamping, strong part access, and repeatable positioning are important. The dovetail holding design helps secure the workpiece from the base, allowing better tool clearance around multiple sides of the part during 5-axis machining and multi-sided machining operations.

Made from chrome steel and aviation aluminum, the holder provides a balance of rigidity, durability, and practical fixture handling. The 5mm dovetail depth and 30–38mm clamping range make it suitable for prepared dovetail blanks, small precision components, and repeatable fixture workflows. With a bottom zero point bolt interface, this holder supports fast positioning and stable mounting in zero-point style CNC fixture systems, EDM workholding setups, and automation-ready machining environments.

What is this Zero Point Dovetail Holder used for?

This Zero Point Dovetail Holder is used for precision CNC workholding, especially 5-axis machining applications where the workpiece needs to be held securely from the base while leaving more sides open for machining access.

Why use a dovetail holder for 5-axis machining?

A dovetail holder allows the part to be clamped from a small prepared dovetail section, which helps improve tool clearance, reduce obstruction around the workpiece, and support multi-sided machining in compact CNC fixture systems.

What is the benefit of the bottom zero point bolt?

The bottom zero point bolt helps mount the holder into a repeatable fixture system, supporting faster setup changes, consistent positioning, and stable workholding for CNC machining, EDM applications, and automation-ready production workflows.
