Stechklemmhalter (Grooving Clamp Holder) – 20 mm Shank, 3 mm Cut Width by Teknik Makina

The Stechklemmhalter is a grooving clamp holder designed for lathe and CNC grooving operations, compatible with Korloy 3C MGM indexable inserts and engineered for rigid toolholding with a 20 mm shank and 180 mm overall length

• 20 mm shank for rigid toolholding
• 3 mm cutting width for narrow grooves
• Compatible with Korloy 3C MGM inserts
• 180 mm overall length for extended reach

Stable clamping for consistent groove quality

The holder’s 20 mm shank and compact mass deliver rigid clamping, which significantly reduces chatter and vibration during grooving operations. This mechanical stability translates into a more consistent surface finish and extended life for indexable inserts. With a net weight of 0.45 kg, the assembly balances stiffness and manageable tool inertia, helping to maintain repeatable results across production batches.

Designed for narrow grooving and reliable insert compatibility

The tool is specified for a 3 mm cutting width and a 35 mm cutting height, dimensions that make it suitable for precise narrow-groove and parting tasks. It accepts 3C MGM indexable inserts and matches the ISO boring-bar designation S20Q 3C-R, ensuring straightforward integration with established insert systems. For workshops unfamiliar with insert codes: the stated cutting width defines the groove width produced, while the cutting height indicates the maximum protrusion the holder accommodates for the insert geometry.

Workshop efficiency through compact reach and simple integration

With an 180 mm overall length and a nominal outer diameter of 26 mm, the holder provides the reach required for deeper approaches without sacrificing rigidity at the toolpost. The MGM clamping type offers dependable retention of the cutting insert, and the straightforward shank size minimises the need for adapter tooling on machines prepared for a 20 mm holder. This design supports fast set-ups and stable machining cycles, which contributes to predictable throughput and less unplanned downtime.
