Parting clamp holder — 25 mm shank, for 3C indexable inserts (Teknik Cutting Tools)

The Parting clamp holder is a dedicated grooving and parting tool holder designed for CNC lathe applications, offering robust clamping for narrow-width cuts and reliable compatibility with standard 3C indexable inserts.

• 25 mm shank diameter for stable clamping
• Compatible with 3C indexable inserts
• 3 mm cutting width for narrow parting cuts
• 200 mm overall length, balanced weight 0.782 kg

Stable clamping and consistent cut quality

The holder is engineered to provide stable clamping and reduced vibration thanks to its solid 25 mm shank and rigid body geometry. This results in improved surface finish and repeatable parting depths, which is especially valuable for series production. The tool’s cutting height of 50 mm and compact footprint ensure that the insert sits securely at the correct centreline, so the machining process is controlled and deviations are minimised. The design is intended to integrate with standard lathe tool posts and to maintain cutting stability during medium-duty parting operations.

Fast insert changes and lower operating costs

Compatibility with 3C indexable inserts enables fast, tool-free or minimal-tool insert indexing and replacement, reducing downtime and increasing machine uptime. Because inserts are indexable, the effective tool life is extended: a single insert offers multiple cutting edges before replacement is required. The 3 mm cutting width supports narrow groove and parting operations, helping to conserve material and lower scrap rates while delivering predictable chip control when paired with suitable inserts and machine parameters.

Compact dimensions for straightforward setup

With an overall length of 200 mm and a nominal diameter of 33 mm, the holder is compact yet accessible for adjustment and inspection. The S25R shank designation aligns with common shank standards, simplifying selection for turret-mounted or post-mounted setups. At a mass of 0.782 kg, the holder is lightweight enough for rapid handling while heavy enough to contribute to system stability, allowing fast clamping without compromising rigidity. Clear dimensional data supports planning for fixture layout and turret clearance.

Practical application and workshop reliability

This clamp-style tool holder is suitable for repeatable grooving and parting tasks where accurate edge location and quick servicing are required. Its simple clamping mechanism and standardised interface make it a pragmatic choice for machine shops seeking efficient changeover routines and predictable process behaviour. Where workflow efficiency and uptime are priorities, the holder contributes to leaner set-up times and steadier production throughput.
