Parting clamping holder L125mm — 25 x 25 mm ISO shank, Torx M5x12 clamp (Teknik Makina)

A Parting clamping holder L125mm engineered for secure clamping of parting and grooving indexable inserts on conventional and CNC lathes.

• 125 mm overall length for extended reach
• 25 x 25 mm ISO 2525 shank for machine compatibility
• Compatible with Tungaloy indexable inserts

Precision shank for consistent parting accuracy

The 25 x 25 mm cross-section, manufactured to the ISO 2525 profile, ensures a consistent fit in standard tool posts and quick-change systems. This measured geometry reduces vibration and positional deviation during cut-off operations, translating into fewer rejected parts and lower secondary machining. A defined shank standard helps maintain setup repeatability when multiple holders are used across a production cell.

Secure clamping for reduced downtime

Clamping is performed using a Torx-mounted screw (M5x12), tightened with a T20 key, which secures the insert carrier without complex adjustments. The straightforward Torx interface provides reliable torque transmission and reduces the risk of screw cam‑out, enabling faster insert changes and minimising operator error. The result is a measurable reduction in tool change time and greater process uptime.

Broad compatibility to simplify tooling management

Designed to accept indexable inserts from Tungaloy, the holder offers compatibility that helps consolidate tool inventories. Using widely adopted insert formats simplifies procurement and allows shops to leverage existing cutting grades and geometries. Where insert choice is important for optimising chip control or tool life, this holder supports proven insert ranges without requiring bespoke adapters.

Robust length and engineering for everyday workshop use

With an overall length of 125 mm, the holder balances reach with stiffness to suit common parting and grooving tasks. The compact, square-profile design concentrates rigidity at the cutting zone, assisting accurate plunge cuts and consistent finish. Supplied by Teknik Makina, this tool holder is intended to be a dependable component in a tooling set-up, enabling predictable tool performance across batch productions.

FAQ

What machines is this holder suitable for?
The Parting clamping holder L125mm is suitable for conventional and CNC lathes that accept a 25 x 25 mm ISO 2525 shank, offering a reliable fit in common tool posts and quick-change systems.

Which inserts can be used with this holder?
This holder is compatible with Tungaloy indexable inserts; selecting the appropriate insert grade allows optimisation for chip control and tool life while using the D856TM holder.

How is the insert clamped and what tool is required?
Clamping is effected by an M5x12 Torx screw; a T20 Torx key is required for secure tightening, ensuring consistent torque and reduced risk of screw damage.

Does the overall length affect stiffness?
The 125 mm overall length provides a balance between reach and rigidity; for deeper operations, consider the effect of cantilevered length on vibration and choose a stiffer set-up if necessary.

Is this holder supplied ready for installation?
The D856TM holder is supplied as a ready-to-fit clamping holder; ensure the correct Torx key and compatible inserts from Tungaloy are used for installation.
