CNC Testing Holders
Precision-ground to tight ISO-AT3 or equivalent tolerances—with runout below ~0.005 mm—our CNC Testing Holders are engineered for consistent tool stability during gauge and inspection procedures. Designed to support accurate alignment in controlled environments using BT40 or BT50 tooling spindles.
Why Choose Our CNC Testing Holders?
- Reliable Calibration Interface. Tailored adapters allow machine runouts and spindle accuracy to be measured with precision tool gauges or test bars.
- Minimal Error Margins. Built for negligible variation under test-load conditions, enabling repeatable spindle readings.
- MBT-Style Adaptable Fit. Available in common BT sizes (BT40-M8 or BT50-M8), suitable for quality control routines on production or inspection setups.
These holders provide a stable toolhold for calibration and performance verification, helping maintain consistent machining precision over time.
