Stechklemmhalter D721TM — Parting tool holder, 3 mm cutting width, 25×25 mm shank (Teknik Makina)

A Stechklemmhalter D721TM crafted for right-hand parting and grooving tasks, optimised for Taegutec 3C TD indexable inserts and designed to fit 25×25 mm tool posts.

• 25×25 mm shank for stable clamping
• 3 mm cutting width for narrow grooves
• Max cutting depth 18 mm for deep parting
• Compatible with Taegutec 3C TD inserts

Greater productivity through stable clamping and defined cutting geometry

The holder’s 25×25 mm shank and compact 150 mm overall length deliver a stiff mounting that reduces vibration and improves chip control during parting and grooving cycles. With a 3 mm cutting width the tool supports narrow kerfs which conserve material and lower cutting forces, enabling higher feed rates on many turning centres. The right-hand cutting orientation provides predictable chip flow and is compatible with standard lathe spindle arrangements. These attributes combine to reduce scrap and increase throughput, making the unit a practical choice for serial work and mixed-batch production.

Fast setup and standardised insert compatibility for smoother workflows

Built to accept Taegutec 3C TD inserts and referenced by ISO designation 2525, the clamping system allows quick insert changes and straightforward tool re‑qualification. The holder’s interface aligns with common tool posts described as 3C-R TD, so replacement tooling is readily available and procurement is simplified. This standardisation shortens downtime during tool changes and helps maintain consistent cutting parameters across shifts, supporting leaner processes and predictable cycle times.

Robust application range and benefits for workshop use

Designed for parting and grooving applications, the tool accommodates a maximum cutting depth of 18 mm, which covers typical deep grooving requirements on medium‑sized workpieces. At a weight of 0.735 kg the construction balances mass for damping with manageable handling during setup. The clamping concept secures inserts against side and axial forces, which supports repeatable positioning and extends insert life when combined with correct cutting data. The result is reliable performance across steel and alloy turning operations where precise kerf width and edge control are required.

FAQ

Which inserts fit this holder?
The D721TM is compatible with Taegutec 3C TD indexable inserts; the holder accepts the standard insert form used for narrow parting and grooving tasks.

What does the ISO designation 2525 indicate?
The ISO designation 2525 refers to the holder’s 25×25 mm shank geometry and fitting standard, simplifying selection for toolposts and fixtures.

Is the holder suitable for deep grooving?
With a maximum cutting depth of 18 mm, the holder supports moderately deep grooving and parting operations typical for medium workpieces.

Can the D721TM be used on CNC lathes and manual machines?
Yes, the design is suitable for CNC turning centres as well as manually operated lathes that accept 25×25 mm tool posts and right-hand cutting holders.

How does the 3 mm cutting width affect machining?
A 3 mm kerf reduces material removal per pass, lowers cutting forces and often improves surface finish, making it preferable for narrow grooves and precise parting.
