The inserts are mounted in the radial insert holder of the bar and secured with a clamping screw — the geometry of the insert produces the internal surface of the bored hole. TiN coating reduces friction and increases durability by 2–3× compared to uncoated inserts.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do you know when to replace an insert?\u003c\/summary\u003e\n\u003cp\u003eSigns of a worn insert: progressively worsening surface finish of the hole, increased force required (the machine slows down), vibration during boring, frayed hole edges.
