20mm Grooving Clamp Holder 11.6mm Head Width, 3.5mm Max Grooving Depth - Teknik Makina

Benefit from a compact, stiff design that combines an S16R 16 mm shank with a 20 mm cutting capacity and a precise 3.5 mm maximum parting depth for reliable, repeatable parting operations; order the holder directly via Metav Werkzeuge or consult the technical team for integration advice.

Parting tool holder K838TM — 20 mm capacity, L 200 mm (Teknik Cutting Tools)

Parting tool holder K838TM is a clamping solution for precise parting and grooving on CNC lathes and turning centres, designed to secure stable cutting performance in workshop and production environments.

• S16R shank with 16 mm diameter
• 20 mm cutting capacity, overall length 200 mm
• Max cutting depth 3.5 mm for precision parting
• Torx T8 fasteners and M2.5x7 screw for reliable clamping

Precision engineering for consistent parting results

The holder is built around the S16R shank format and a 16 mm shaft diameter, providing a familiar interface for standard toolposts and reduced set-up time. The 20 mm nominal cutting capacity and 11.6 mm cutting-head width translate into narrow, controlled parting cuts that limit deflection and vibration. This configuration helps to maintain surface finish and concentricity during interrupted cuts while supporting high-repeatability production runs. The design prioritises rigidity and geometric stability, which converts into fewer rejects and less rework for routine turning operations.

Stable setup and predictable cutting performance

With an overall length of 200 mm and a cutting height of 25 mm, the holder strikes a balance between accessibility and stiffness for medium-reach parting tasks. The documented maximum parting depth of 3.5 mm is intended for precise, shallow-to-moderate depth cuts where control is essential. At just 0.302 kg, the assembly is light enough for quick tool changes but engineered to dampen chatter when clamped correctly. Clear, measurable specifications make it straightforward to calculate tool overhang, reachable diameter and clamping torque requirements for defined machining strategies, reducing the need for trial-and-error during process setup.

Practical serviceability and workshop integration

Maintenance and repeatable clamping are simplified by the use of Torx T8 drive elements and the M2.5x7 fixing screw, enabling fast insert and clamp replacements with standard hand tools. As a compact parting tool holder, K838TM is ready for direct integration into existing tool posts and post-type toolholders that accept the S16R standard. The compact head geometry reduces interference for close-proximity cutting and eases access in multi-tool turrets.

FAQ

What shank size is required for this holder?
The holder uses the S16R standard and accepts a 16 mm shank format for secure mounting in compatible toolposts.

What is the maximum parting depth?
Maximum parting depth is 3.5 mm, suitable for controlled, precise parting and grooving operations.

Which overall length should be expected when planning tool overhang?
Overall length is 200 mm, which should be considered when calculating overhang to preserve rigidity.

What fastening hardware is used for the clamping assembly?
Clamping and service use Torx T8 drive elements and an M2.5x7 screw for reliable, repeatable tightening.

Is the holder suitable for turret and post-style toolholders?
The geometry and S16R shank designation make the holder compatible with standard post-style toolholders and turrets that accept the S16R format; confirm turret clearance and toolpost interface before installation.
