Grooving and parting toolholder (D808TM) — left‑hand, 25 mm head width by Teknik Makina

The grooving and parting toolholder (D808TM) is a left‑hand turning toolholder intended for accurate parting and narrow grooving on conventional and CNC lathes, engineered to accept Korloy MGM 4 indexable inserts.

• Left‑hand cutting direction
• 25 mm head width
• 4 mm cutting width
• Compatible with Korloy MGM 4 inserts

High‑precision parting for reliable cycle times

The D808TM delivers a consistent cut through a dedicated geometry that focuses on stability and chip control. With a 4 mm cutting width and 20 mm max parting depth, the holder is suited to common parting‑off and grooving tasks where repeatable, burr‑reduced results are required. The left‑hand orientation ensures correct cutting forces for left‑handed operations and avoids unexpected tool deflection, improving first‑pass yield and reducing rework.

Stable clamping and robust dimensions for process security

Built with a 25 mm head width and a cutting height of 45 mm, this holder gives secure support for inserts during interrupted cuts. The shank geometry, identified as ISO 2525, and a solid Ø 60 mm section combine with a total length of 150 mm to provide the rigidity needed for tighter tolerances. At 0.712 kg, the toolholder balances mass for vibration damping while allowing straightforward handling during tool changes.

Compatibility that simplifies toolroom logistics

Acceptance of Korloy MGM 4 inserts and a clamping/bar designation of 4C‑L (60‑80) reduces inventory complexity by matching common insert families. The holder supports up to 80 mm cutting diameter, enabling use across a range of component sizes. Compatibility with established insert standards shortens set‑up time and makes insert replacement intuitive for machinists, helping to sustain machine uptime and throughput.

Where this holder adds value in production

Designed for job shops, maintenance departments and small series production, the holder is effective for precise parting, narrow groove finishing and operations requiring predictable chip control. The dimensional data and compatibility make it straightforward to integrate into existing tool sets, while the construction delivers the process reliability expected in industrial turning environments. For specific machining scenarios, Metav Werkzeuge can advise on insert grades and cutting parameters to align the holder with material and speed requirements.
