Parting and Grooving Clamp Holder D770TM — 4 mm cutting width, 25 x 25 mm shank (Teknik Makina)

A robust Parting and Grooving Clamp Holder D770TM designed for right-hand parting and grooving tasks on conventional and CNC lathes, suited to installations using 4C GRP indexable inserts

• 4 mm cutting width for narrow grooves
• Max parting depth 20 mm
• 25 x 25 mm shank, 150 mm overall length
• Compatible with ISCAR 4C GRP inserts

Accurate grooves and clean parting that reduce rework

The D770TM delivers a 4 mm cutting width and a maximum parting depth of 20 mm, enabling precise groove profiles and reliable part separation in repetitive production runs. The defined cutting width controls chip formation and minimises lateral vibration, which translates into fewer rejects and lower rework rates. For users unfamiliar with insert geometry, the cutting width refers to the effective material removed across the tool flank; a narrow width like this is ideal for fine grooves and tight-tolerance parting where edge control and surface finish matter.

Stable mounting and quick integration into tool setups

With a 25 x 25 mm shank and 150 mm overall length, the holder fits standard tool posts while providing the reach required for common turning setups. The ISO designation 2525 and the matching borestring reference 4C-R GRP make the interface predictable and compatible across systems. The holder is prepared for right-hand cutting, which simplifies tool orientation during set-up. A mass of approximately 0.747 kg contributes to rigidity without excessive overhang, supporting consistent cutting forces and reduced chatter during both groove forming and parting-off operations.

Compatibility with indexable inserts for flexible workshop workflows

The toolholder is specified for 4C GRP indexable inserts and explicitly compatible with ISCAR insert types, allowing workshops to standardise on a small range of inserts for multiple operations. Interchangeable insert systems reduce inventory complexity and shorten downtime when changing grades or geometries. The clamp-style mounting supports straightforward insert replacement and re-tightening, which is particularly useful in high-mix, low-volume environments where rapid tool changes preserve machine uptime and throughput.
