Techniks SYIC-29276 CAT50 Shrink-Fit Chuck (SFC) with an 18 mm internal bore and 100 mm projection is designed for CAT50 spindles. It has an overall length of 201.6 mm, weighs 3.45 kg, uses an M12 pull stud, and requires a minimum shrink torque of 250 N·m to secure tooling. Concentricity is specified within 5 μm (TIR within 5 μm), and the slim design emphasizes rigidity; a 6-hole balance option with balancing screws is available on request. Standard balance is rated to 25,000 rpm (G2.5), making it suitable for high-speed milling when paired with CAT50 spindles.
