Grooving clamping holder K726TM — 25 mm shank, 4 mm cutting width by Teknik Makina

The Grooving clamping holder K726TM is a turning tool holder for external grooving and cut‑off applications, engineered for compatibility with Sandvik 4C inserts and for installation in lathes with an S25R shank interface

• Robust 25 mm shank for standard toolposts
• Precise 4 mm cutting width for narrow grooves
• Compatible with Sandvik 4C indexable inserts
• 200 mm overall length for extended reach

Stable grooves through controlled cutting geometry

The holder is designed to deliver consistent groove quality by combining a narrow cutting width with a stable clamping arrangement. The 4 mm nominal cut width suits slotting and parting operations where tight tolerances are required; using a standard insert form such as Sandvik 4C reduces variation between changeovers. For users less familiar with insert terminology: indexable inserts are replaceable cutting tips held in a clamp — this arrangement minimises downtime because only the insert is replaced, not the whole tool body. The result is improved process uptime and repeatable groove dimensions in production runs.

Seamless integration with common turning systems

Fitting is simplified by the ISO shank designation S25R and the 25 mm shank diameter, which match many conventional toolposts and turret systems. The 200 mm overall length and a body diameter of 32 mm provide reach without excessive overhang, helping to reduce vibration. The S25R code denotes a straight shank with a right-hand orientation; in practice this means the holder mounts in the usual way on right‑hand turning setups. Clear mechanical compatibility lowers commissioning time and lets machining centres resume production faster.

Practical clamping and economical tool management

The clamping concept is compatible with the clamping bar type 4C‑R‑123 SDV, allowing secure retention of the insert during heavy cuts. The design supports straightforward indexable insert replacement, which keeps tooling stock simple — holding to one insert family like 4C saves purchasing and storage effort. With a modest mass of 0.772 kg, the holder is light enough for agile tool changes yet rigid enough to maintain cutting stability; this combination helps to reduce scrap rates and overall production cost per part.

FAQ

Which inserts fit this holder?
The holder accepts 4C style indexable inserts and is specified for use with Sandvik 4C inserts; this ensures availability of cutting grades and geometries for different materials.

What shank size and mounting standard does it require?
Mounting uses a 25 mm shank with ISO designation S25R, suitable for standard right‑hand turning toolposts and turrets designed for 25 mm shanks.

What groove dimensions can be achieved with this holder?
The tool is configured for a 4 mm nominal cutting width; the clamping and cutting height (40 mm) support stable cut engagement for narrow slots and light parting tasks.

Is the holder suitable for long‑reach operations?
With an overall length of 200 mm and a 32 mm body diameter, the holder provides increased reach while maintaining rigidity for many external grooving tasks.

How is the insert secured and exchanged?
The clamping arrangement is compatible with the 4C‑R‑123 SDV clamping bar type, enabling secure retention during cutting and quick insert changes to keep downtime low.
