Parting and grooving clamp holder K684TM — 25 mm shank, 4 mm cutting width (Teknik Makina)

A compact parting and grooving clamp holder designed for precise turning tasks and compatible with ZCC 4C ZT.D indexable inserts.

• 25 mm shank for secure mounting
• Compatible with ZCC 4C ZT.D inserts
• 4 mm cutting width for precise grooves
• 200 mm overall length for deeper cuts

Consistent parting performance through rigid design

The holder delivers consistent results thanks to a 25 mm shank and a robust body that reduce vibration during cut-off and grooving operations. The combination of secure clamping and a defined cutting height of 35 mm supports repeatable geometry and reduces scrap rates in batch production. For workshops aiming to increase first-pass quality, the rigid construction of the holder contributes to steady tool life and predictable surface finish, helping to lower rework and improve throughput.

Insert compatibility and straightforward set-up

Engineered for use with ZCC 4C ZT.D inserts and identified by the ISO-style designation S25R, the tool accepts common clamping bars such as 4C-R ZT.D, enabling rapid replacement and minimising machine downtime. Clear compatibility with established insert systems simplifies stock management and makes the holder a practical choice for mixed-production environments. The straightforward interface with standard inserts reduces set-up time on the lathe and supports a smoother production flow.

Accurate groove geometry with controlled cut parameters

With a defined cutting width of 4 mm and a cutting height of 35 mm, the holder is optimised for narrow groove and parting tasks where dimensional control matters. The nominal overall length of 200 mm and external diameter of 33 mm provide reach for deeper operations while maintaining rigidity close to the workpiece. Such geometry helps to maintain dimensional tolerances and minimise thermal or elastic deformation during extended cycles, which is vital for repeatable batch performance.

Practical workshop benefits and reliability

Weighing in at 1.578 kg and built by Teknik Makina, the unit is a reliable addition to tool sets used in conventional and CNC turning. Compatibility with ZCC inserts and an ISO-compatible shank designation mean easier procurement and integration into existing tooling families. For purchasers seeking a balance of mechanical stability, straightforward maintenance and proven compatibility, this clamp holder supports efficient production and a lower total cost of operation through reduced set-up complexity.
