32 ISCAR GENERAL DRILLING HANDBOOKEM Side Clamp ChuckEM side clamp chuck suitable for cutting tools with Weldon and Whistle-notch shanks. The principle of operation is simple: the tool shank has a flat area, clamping is carried out by tightening the screw, the screw rests on the flat area, reliably fixing the tool.The difference between chucks for the Whistle-Notch shank and Weldon shanks is the orientation of the clamping screw.EM Side Clamp Chuck with Weldon ShankEM Side Clamp Chuck with Whistle Notch Shank20The clamping screw in the chuck for the Weldon shank is perpendicular to the central axis of the cutting tool, while the clamping screw in the chuck for the Whistle-Notch shank is at an angle in accordance with the flattened part on the shank. This allows the screw not only to push the cutting tool against the wall of the chuck but also to pull it inward. The primary advantages of the EM side clamp chuck are its relatively low cost and the absence of torque transfer limitations.Tool Side Selection ConsiderationsWhen selecting the tool side, factors such as the drill shank type and the following parameters should be considered:%u2022 Run Out (OD/ID)%u2022 Gripping/ Torque Transmission (Nm/lbs*ft)%u2022 Vibration Damping%u2022 Balancing Quality (Grade/RPM)%u2022 Rigidity/Stiffness %u2022 Handling and Operability%u2022 Shape limitations%u2022 Maintenance and Tool Life%u2022 Flexibility / Versatility%u2022 Weight Limitation
