Be sure that which you have 100% of your holder.
When we buy a cheap holder, use a long extension, do not change an accessory periodically, do not clean an insert seat or a gripper faces, use a weak holder connection, use not engineered holder design and do not use torque meter screw driver or wrench, it means we lost a portion of our holder’s capabilities, that, lead to decreasing productivity and increasing tooling cost.
Let me explain more, when there is no holder at all, machining is not possible (0% machining) but when we have a long damaged holder it means we 70% of our machining possibilities.
