Teknik Makina Parting and Grooving Clamping Holder K677TM — 25 mm shank, 4 mm cutting width

Teknik Makina Parting and Grooving Clamping Holder K677TM is a purpose‑built clamping tool for parting and grooving operations in turning machines, offering a rigid 25 mm shank and a narrow 4 mm cut for accurate, repeatable results

• Robust 25 mm shank for stable toolholding
• Compatible with 4C indexable inserts (ISCAR-compatible)
• 4 mm cutting width for fine grooving control
• 200 mm overall length for extended reach

Reduced cycle times through controlled cutting dynamics

The holder is engineered to improve process efficiency by combining a 25 mm shank with a compact cutting geometry. The slender 4 mm cutting width and 40 mm cutting-edge height reduce cutting forces during parting and narrow‑groove turning, which in turn lowers vibration and improves surface finish. These mechanical benefits support shorter machining cycles and more consistent batch quality, helping production lines run with fewer interruptions and less rework.

Fast setup and seamless integration into existing toolchains

Designed for compatibility, the clamping system accepts 4C indexable inserts and is ISCAR-compatible, simplifying inventory and substitute options. The shank interface labels S25R and 4C-R DGN indicate standardised mounting dimensions for straightforward insertion into common tool posts and holders. Reduced setup complexity translates into less downtime at changeover and a more efficient toolroom logistics flow, especially where mixed‑brand insert stocks are used.

Predictable rigidity and reach for repeatable results

With a 200 mm overall length and a 31 mm diameter at the tool body, the holder delivers the reach required for deeper set‑ups while maintaining rigidity that keeps cuts stable. The relatively light mass of 0.802 kg promotes easier handling during tool changes without compromising balance on the lathe. These dimensional characteristics combine to provide predictable cutting behaviour across repetitive runs, benefitting shops that prioritise consistent tolerances and surface quality.

FAQ

Which insert type fits this holder?
The holder accepts 4C indexable inserts and is specified as ISCAR-compatible, allowing use of standard 4C parts in the Teknik Makina K677TM clamping system.

What shank and mounting designations apply for mounting?
Mounting follows the S25R shank designation and the 4C-R DGN holder interface, ensuring compatibility with common turning tool posts that accept these standards.

Is the holder suitable for deep grooves or long reach work?
The 200 mm overall length provides extended reach for deeper set‑ups while the 31 mm diameter preserves rigidity for controlled cutting in parting and grooving tasks.

How does the holder affect vibration and surface finish?
The combination of a 25 mm shank, compact cutting width and balanced mass (0.802 kg) reduces vibration during narrow cuts, improving surface finish and repeatability when used under appropriate machining conditions.

Can the Teknik Makina K677TM be used with inserts from different manufacturers?
Yes — the K677TM is designed to be ISCAR-compatible and accepts common 4C indexable inserts, which facilitates cross-brand use and simplifies tooling inventories.
