MasterBar CAT

Our BT runout master taper is designed to check and align machine spindles.
Cylindricity ≤2 µm measured on the cylindrical shank. Runout ≤3 µm measured from the cylindrical shank to the taper. Axial deviation ≤0.5 µm (BT+ only) measured from the flange to the taper.
Paper and digital inspection certificate. QR code and serial number for digital access. Periodic inspection for greater reliability and lower spindle risk.
