1 Radial runout may affect tool life. 2 Radial rigidity for Weldon holder is low at a direction perpendicular to the screw. 3 Accepts different shank diameters through the use of reduction sleeves or due to collapse range. 4 Collet chucks and milling chucks may require the use of a torque or special wrench; Shrink Fit adaptor requires a shrinking unit.
