K702TM Grooving clamp holder — 20 mm shank, 3 mm cutting width (Teknik Makina)

A K702TM grooving clamp holder designed for secure clamping of 3C indexable inserts, optimised for precision parting and grooving operations on conventional and CNC lathes

• Secure clamp for 3C indexable inserts
• 20 mm shank for standard toolposts
• 3 mm cutting width for precise grooves

Stable clamping for repeatable grooves

The holder provides a robust clamping concept that reduces insert movement under load, giving consistent cutting geometry across batches. With a 20 mm shank, the tool integrates with common toolposts and holders for a secure fit, while the 3 mm cutting width is intended for fine grooving and narrow parting tasks. This combination improves dimensional repeatability and reduces rework, which supports efficient shop-floor processes.

Geometry tailored for deeper grooving operations

A nominal cutting height of 35 mm and an overall length of 180 mm offer the clearance and reach required for a range of turned component profiles. The taller cutting height allows the cutting edge to engage material at the correct centreline on many setups, while the 180 mm length balances reach and rigidity. These dimensions help maintain a stable cut path and reduce the tendency for chatter during moderate-depth grooving operations.

Compatibility that simplifies tooling choices

Designed for use with 3C indexable inserts and explicitly compatible with ISCAR insert geometries, the holder reduces complexity when specifying consumables. The tool is identified by shank designation S20Q and clamp holder designation 3C‑R GRP, enabling straightforward matching with existing insert stocks and holders. This compatibility streamlines ordering and minimises downtime when inserts are changed.

Compact mass and workshop handling advantages

Weighing 0.463 kg, the holder combines manageable handling with sufficient mass to dampen minor vibrations. Its nominal diameter of 26 mm and standardised interface mean straightforward mounting and replacement, helping to keep set-up times short. The compact design supports flexible placement on the turret or toolpost without excessive overhang, aiding both manual and automated lathe applications.
