Tool set-up: how to use parting and grooving tools

Good quality in parting off and grooving is mainly dependent on the tool system and how it is used together with the cutting material.


For an optimal parting tool set-up use a tool holder with a short overhang to avoid vibration. We recommend to use a sub-spindle if available.


When machining with long overhangs, it is especially important to mount the bar correctly to ensure enough clamping contact. Recommended clamping length is 4 x bar diameter d. This will result in a stable parting tool set-up. Cylindrical adaptors can be clamped in split sleeves. Large adaptors can be clamped using two split bearing caps.


​Tool holding

The right tool holding solution can improve the productivity and performance of the cutting tool dramatically.

Coromant Capto® is a modular quick change tooling concept which when directly integrated in the spindle increases stability and versatility in, for example, multi-task machines, machining centres with turning capability and vertical lathes.


EasyFix sleeves are a set-up time reducing solution for cylindrical adaptors. A spring plunger mounted in the sleeve clicks into a groove in the bar to guarantee the correct centre height.


The QSTM holding system is a quick change tool holder to maximize effective production time in sliding head machines.

Silent ToolTM tool adaptors are designed to minimize vibration through a dampener inside the tool. These tools are mostly used for long overhangs however, even with shorter overhangs (3xD), large productivity increases and surface quality improvements are to be gained.


Parting blades

Parting blades and tool blocks offer a tool system for parting off, deep grooves and long overhangs. Precision coolant is optional for all blades. No connection hoses or pipes are needed. Adaptors are available for most machine types.
