Added strength for tool holder and insert clamping
Tool and insert clamping are next in line when getting ready to turn case-hardened steel surfaces.
Tool holder deflection increases by the cube of the added overhang, so simple mathematics tell you to keep the overhang as short as possible or, if feasible, use a rigid tool with a large cross-section.
To further improve stability, especially for small diameter tools, consider using carbide shanks. |

It pays to keep overhang as short as possible. |

| With a clamping force of several tons, the tapered polygon and flange location face of the Coromant CaptoŽ tooling system result in a strongly clamped joint that is extremely resistant to bending and twisting. |
Impressive clamping strength from the Coromant Capto tooling system. |

| In addition to strong tool holder clamping, HPT also requires a rigid means of clamping inserts. CoroTurnŽ RC and CoroTurnŽ 107 provide this rigidity by clamping the insert in two directions, combining downward forces with insert positioning accuracy. |

CoroTurn RC clamping for negative inserts - fast and easy insert indexing. |  | 
CoroTurn 107 - positive inserts are held in place with a screw clamp system. |
