Parting Tool Holder D810TM — left‑hand parting and grooving holder by Teknik Makina, for Korloy MGM‑4 inserts

The Parting Tool Holder D810TM is a left‑hand grooving and parting holder designed for medium‑to‑heavy turning, offering a compact 25 mm cutting head and compatibility with Korloy MGM‑4 indexable inserts for repeatable cut‑off performance.

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

High‑precision parting where cycle time matters

The D810TM parting holder combines a stable clamping design with a compact head geometry to reduce vibration during cut‑off operations, which increases tool life and surface quality. The 25 mm cutting head and 45 mm cutting height give a secure platform for short, repeatable cuts while the 4 mm cutting width is optimised for narrow parting slots. Reduced chatter translates into fewer re‑works and a more predictable production rhythm, particularly in batch machining where consistent part separation is critical.

Built for compatibility and fast set‑up on existing toolposts

Specified as an ISO 2525‑type clamping holder and matching the 4C‑L (80–110) shank range, this holder integrates quickly into standard turret toolposts and modular boring bars. The D810TM accepts Korloy MGM‑4 inserts, allowing workshop managers to use a familiar insert family and minimise inventory complexity. Clear labelling of shank and insert standards streamlines tool selection and reduces setup time between jobs, supporting efficient changeovers and reduced machine downtime.

Designed to sustain continuous production with safe clamping

A dedicated clamping mechanism and a relatively low mass of 0.7 kg provide secure holding without excessive tool overhang; the holder’s maximum parting depth of 20 mm accommodates many common turning tasks while limiting leverage that causes deflection. The maximum cutting diameter of 110 mm and a shaft cut length of 25 mm align the holder’s capabilities to mid‑range lathes and bar‑turning applications, making it a dependable choice for workshops seeking consistency under repetitive loads.

Practical benefits explained for production planning

Using a purpose‑built parting holder reduces scrap by improving the initial cut and limiting tool breakage. The D810TM’s geometry prioritises chip control and rigidity: the stepping depth and cutting height control how chips form and evacuate, which is especially important on long runs or when machines lack sophisticated chip conveyors. Choosing a holder that matches insert geometry and shank standards enables predictable process planning and easier operator training.

FAQ

What insert types fit this holder?
The D810TM accepts Korloy MGM‑4 indexable inserts; the holder is configured for those insert geometries and clamping sizes.

Is the holder suitable for right‑hand operations?
This parting holder is manufactured for a left‑hand cutting direction; a right‑hand variant should be selected for opposite cutting orientation.

Which shank sizes are compatible with the D810TM?
The shank rod designation is 4C‑L (80–110), matching common turret and bar tool interfaces in that range.

What maximum parting depth can be achieved?
The holder’s maximum parting or cutting depth is 20 mm, designed for medium‑duty parting tasks.

Can this holder be used on small lathes?
With a diameter of 80 mm and overall length 150 mm, the holder suits many standard turret setups; ensure toolpost clearance and shank compatibility before fitting.
