Grooving clamping holder K672TM — 20 mm shank, 180 mm overall length (Teknik Makina)

The Grooving clamping holder K672TM is a parting and grooving holder designed for turning operations, offering compatibility with ISCAR 3C inserts and an ISO S20Q shank designation for reliable workshop integration

• 20 mm shank diameter for stable mounting
• 180 mm overall length for deep reach
• Compatible with ISCAR 3C inserts
• 3 mm cutting width, 35 mm blade height

Consistent grooves through secure clamping and geometry

The holder is engineered to provide secure clamping of ISO-style inserts, reducing micro-movement that can distort groove dimensions. With a 20 mm shank and a firm interface to ISO S20Q toolposts, the arrangement improves repeatability across batches and reduces rework. The specified 3 mm cutting width and 35 mm cutting height define the controlled cut profile and are suitable for standard parting and narrow-grooving operations, helping to maintain tolerance stacks and surface finish in serial production.

Faster set-up and reliable tool changes for higher throughput

A clear ISO designation and the alternate holder code 3C‑R DGN enable rapid identification and quicker tool changes at the machine, shortening non-productive time. The 180 mm overall length allows access into deeper work while the moderate mass (0.446 kg) keeps spindle load predictable, which supports steady cutting conditions. For production shops and maintenance teams, this translates into more predictable cycle times and simpler inventory management when matching holders to ISCAR 3C inserts.

Robust compatibility across conventional turning tasks

The design supports common grooving and parting applications on lathes and turning centres that accept ISO S20Q shanks, making the holder versatile for general workshop use. Compatibility with widely used 3C insert geometries ensures broad tooling availability and reduces the need for multiple specialised holders. The combination of standardised interfaces and straightforward geometry helps technicians achieve consistent cut quality with familiar insert styles.
