Shim Shim pin a Easy and secure insert retention. a World class cutting edge indexing accuracy. Holder New optimized clamp bridge The clamp bridge features a new geometry that is optimized for promoting good chip flow while maintaining tool rigidity. This has been achieved by using CAE design analysis technology to avoid chip packing problems. This new bridge type is also compatible with both right and left hand tool holders. Higher vibration resistance and chip discharge properties The dimple boring bar features excellent vibration resistance properties and through coolant holes for better chip discharge. In addition, a scale for easy overhang length setting is etched on the body. Dimple Scale Coolant Hole Special surface treatment The body and clamp bridge has been treated with a special surface coating for higher corrosion and abrasion resistance. Double-ended torx hole clamp screw Equally sized torx holes are provided on both ends of the clamp screw, making it easy to attach and remove the insert even when an inverted holder is used, thus ensuring rapid insert indexing and secure clamping.

Guide: Turn the clamp screw 2-3 rotations from the fully clamped state to ensure clearance. awhen clamping the insert, be sure to use the wrench provided. Over tightening may cause damage to the clamp bridge and the torx holes of the clamp screw. (The appropriate tightening torque is 5.0Nm for a wrench size; 3.5Nm for a type.) Unclamped state ed state Clearance bridge protrusion screw screw Insert Insert aif chips interfere or wrap around the clamp screw, the selected insert breaker may not be suitable. In this case, a review of the insert breaker is recommended as this may affect the surface finish accuracy of the workpiece. 10

Dimensional control becomes easier due to a higher cutting edge positioning accuracy. Higher clamping rigidity of the insert and a 20% increase in the number of components machined.
