Stechklemmhalter K616TM – Grooving clamping holder with 4 mm cutting width (Teknik Makina)

The Stechklemmhalter is a robust grooving clamping holder for CNC turning applications, designed to accept 4C MGM inserts and to provide rigid support for precision parting and grooving operations.

• Solid 40 mm shank for stable clamping
• Compatible with Korloy 4C MGM inserts
• Cutting width 4 mm for precise grooving
• Overall length 300 mm for deep turning operations

Maximum stability for repeatable grooves and reduced vibration

The holder is engineered around a 40 mm shank and a substantial Ø47 mm body, which together increase stiffness at the tool tip and reduce chatter under load. This rigidity translates into consistent groove geometry and predictable tool life when machining repeat batches. The design also contributes to safer set‑up on CNC lathes, as the mass distribution and the weight of 2.942 kg damp vibrations that would otherwise affect surface finish. For manufacturers seeking measurable improvements in process stability, the combination of shank diameter and overall mass offers a clear productivity advantage.

Fast insert mounting and proven insert compatibility to cut set‑up time

Fitted for the MGM clamping system and the ISO bar designation S40T 4C‑R, the holder accepts Korloy 4C MGM inserts, enabling quick replacement and secure clamping without additional adaptors. The 4 mm cutting width and 60 mm cutting height are optimised for narrow grooving and parting tasks, allowing accurate control of chip formation and groove dimensions. The straightforward interface between holder and insert reduces set‑up time and limits the need for repeated adjustments, which supports higher uptime and a faster route to production readiness.

Built for deeper turning tasks while maintaining precision

With an overall length of 300 mm, the tool is suitable for operations that require reach beyond short overhangs, while the geometry of the clamping block keeps the cutting edge firmly located. The bar designation S40T 4C‑R indicates a standardised shank form for integration into existing toolposts and turret systems, simplifying implementation on the shop floor. The holder’s balance of length and stiffness helps to preserve dimensional accuracy in groove depth and wall straightness, making it a reliable choice for both repeat manufacturing and prototyping runs where groove integrity matters.
