K681TM Grooving Clamp Holder — 25 mm shank, 3 mm cutting width (Teknik Makina)

The K681TM grooving clamp holder is a lathe-mounted toolholder engineered for secure clamping of 3C ZT.D indexable inserts, providing precise grooving and parting operations in turning applications

• Robust 25 mm shank for stable mounting
• Accepts 3C ZT.D indexable inserts
• 35 mm cutting height for consistent engagement
• 200 mm overall length for extended reach

Engineered stability for repeatable grooves

The holder is built with an emphasis on rigidity and repeatability: the 25 mm shank and a body diameter of 33 mm combine to reduce deflection during cut entry, while the measured weight (1.576 kg) helps damp vibration. Together these attributes maintain a stable tool position, which translates into consistent groove geometry and longer insert life. For workshops aiming to reduce scrap and rework, this mechanical stability is a clear operational advantage.

Precise clamping designed for indexable inserts

Compatibility with 3C ZT.D indexable inserts and a 3 mm cutting width makes the clamp ideal for fine grooving tasks and narrow parting lines. The holder accepts ISO shank configuration S25R and the related designation 3C‑R ZT.D, enabling quick insert changes and repeatable seating accuracy. Indexable inserts offer predictable cutting edges and straightforward indexing; when combined with a reliable clamping system, tool changeover times are reduced and process reproducibility improves.

Practical design for workshop efficiency

At 200 mm overall length the toolholder offers reach for deeper set-ups while maintaining manageable overhang. The 35 mm cutting height ensures correct edge alignment on most standard turning centres, reducing the need for shims or complex set-up procedures. This straightforward compatibility and robust mechanical design support faster set-ups and steady production runs, helping to keep cycle times predictable and tooling costs under control.
