Stechklemmhalter K668TM — Parting tool holder with 32 mm shank and 55 mm cutting height (Teknik Makina)

The Stechklemmhalter is a purpose-built parting tool holder for indexable grooving inserts, engineered for lathe-based parting and grooving operations where repeatable cut control and easy insert replacement are required.

• 32 mm shank diameter for stable clamping
• 55 mm cutting height for deep grooving
• Compatible with Korloy KGEVR-KGMN 400 inserts
• 250 mm overall length for extended reach

Stable clamping for accurate, repeatable parting

A robust toolholder backbone is essential when consistent parting quality is required across batches. The parting tool holder features a 32 mm shank, providing a solid contact surface in the tool post and reducing micro-movement during cut engagement. With a 55 mm cutting height and a 4 mm cutting width, the holder is dimensioned to support standard grooving depths while maintaining rigidity and thermal stability. The result is improved repeatability between operations, fewer scrap parts and a reduction in rework cycles — a direct contribution to process efficiency.

Fast changeover through standard insert compatibility

Minimising machine downtime is achieved by using established insert formats and secure clamping. This holder accepts Korloy KGEVR-KGMN 400 indexable inserts and matches common bore and clamp standards such as S32S 4C and the KGMN bar designation. Compatibility with these widely used components simplifies stock management and shortens changeover procedures. The standardized interface enables quick, reliable insert seating and torque-controlled clamping, which is beneficial for workshops aiming to increase machine uptime and throughput.

Designed to withstand workshop demands

Long tool reach and a balanced mass distribution matter when access and vibration control are priorities. With a 250 mm overall length and a mass of 1.623 kg, the holder delivers the reach necessary for deeper parting operations while preserving stability under feed forces. The geometry has been developed to reduce chatter and to support consistent chip flow, which extends insert life and lowers tooling costs per component. The construction is tailored to provide dependable service in job shops and production environments where robustness and low maintenance are prized.

Where this holder excels in production

The holder is particularly suited to turning centres and manual lathes performing precision parting or grooving on standard workpiece diameters; the 40 mm diameter reference and the bar-compatible shank make it applicable for setups requiring moderate reach and a secure clamping interface. Applications include component cut-off, internal and external grooving where a controlled slot width and depth are critical. The combination of a standard insert family and a rigid mounting profile supports repeatable results and straightforward process validation in small to medium production runs.
