125mm Stechklemmhalter 3°? 1616 3C-L DGN For 3C DGN Innenkühlung Linksschneidend - Teknik Makina

This parting and grooving solution combines robust clamping with standardised dimensions for reliable, repeatable cuts — the 16 x 16 mm shank (ISO 1616) and 3 mm cutting width deliver consistent results while the left-hand configuration suits common lathe setups; order via Metav Werkzeuge or ask our consultants for application-specific guidance.

Parting and Grooving Tool Holder D731TM — 16 x 16 mm shank, left-hand, Teknik Makina

The Parting and Grooving Tool Holder D731TM is a left-hand insert holder designed for precision parting and grooving tasks on CNC lathes, compatible with 3C DGN indexable inserts for standard industrial production

• 16 x 16 mm shank, ISO 1616
• Compatible with 3C DGN inserts (ISCAR)
• Left-hand cutting direction, 3 mm blade width
• 125 mm overall length, max 19 mm cutting depth

Solid shank and repeatable set-up for precise cuts

A compact, rigid design provides a stable platform for narrow grooving and parting operations. The 16 x 16 mm shank and ISO 1616 designation ensure compatibility with common toolposts and quick mounting on turret stations. This dimensional standardisation reduces set-up time and improves repeatability, which is essential where consistent part geometry is required. The holder’s construction concentrates clamping force around the insert pocket to limit vibration and maintain a predictable cutting line.

Compatibility that simplifies tooling logistics

Built for use with 3C DGN indexable inserts and matched to major insert makers such as ISCAR, the holder lowers stock complexity by accepting widely available inserts. The modest 3 mm cutting width and a maximum 19 mm cutting depth suit routine parting and light grooving tasks, allowing controlled chip formation and easy chip evacuation. The left-hand cutting direction is specified for operations on setups where the tool must enter from the workpiece right side, providing a clean, predictable chip flow and reduced rework.

Practical handling and workshop efficiency

With an overall length of 125 mm and a lightweight construction of 0.253 kg, the tool holder is easy to position and clamp while remaining rigid during cutting. The clamping mechanism secures the insert securely, enabling short changeover times and stable cutting performance across production runs. For small-batch or repair work, the compact footprint helps to avoid collisions and keeps the toolpath close to the machine centre, supporting safe single-setup machining without excess overhang.

Typical applications and support for industrial use

The holder is tailored for precision parting-off, narrow groove profiling and short-face grooving on shafts and turned components. It performs well in series production and job-shop environments where consistent slot widths and clean part separation matter. For advice on integration into existing tooling systems or confirmation of insert interchangeability, Metav Werkzeuge provides application guidance and can assist with selection of compatible inserts and fastening hardware.

FAQ

Which inserts are compatible with this holder?
The D731TM accepts 3C DGN indexable inserts; inserts from major makers such as ISCAR fit the pocket geometry and secure clamping.

Is this holder left or right cutting?
This tool holder is specified for left-hand cutting, suitable for set-ups where the tool enters the workpiece from the right.

What cutting width and depth are possible with the holder?
The holder supports a 3 mm cutting width with a maximum parting/grooving depth of 19 mm.

What are the shank dimensions and overall length?
Shank dimensions are 16 x 16 mm (ISO 1616) and the overall length is 125 mm, compatible with standard 16 mm toolposts.

Is the D731TM suitable for heavy roughing operations?
The D731TM is optimised for precision parting and narrow grooving; its design emphasises rigidity and control rather than heavy-material stock removal
