Key dimensions are projection length A = 50 mm and body diameter D = 28 mm, which influence reach and rigidity during machining. How does the Weldon clamping affect performance? Weldon clamping offers positive mechanical drive via the lateral flat, improving torque transmission and reducing the risk of tool slippage under heavy cutting forces.
