Stechklemmhalter D791TM — Parting tool holder with 4 mm cutting width by Teknik Makina

The Stechklemmhalter D791TM is a robust parting and clamping holder designed for external grooving and parting on conventional and CNC lathes, offering a compact shank and compatibility with common indexable inserts.

• 4 mm cutting width for narrow grooves
• Max cutting diameter 150 mm for external turning
• Compatible with Korloy MGM 4 inserts
• Weight 0.712 kg for stable clamping

Efficient machining through precise geometry and compatibility

The holder’s 4 mm cutting width and controlled cutting height of 45 mm are engineered for repeatable groove profiles and reliable parting. The compact shank length of 25 mm and overall length of 150 mm make the component straightforward to integrate on standard toolposts. Designed to accept Korloy MGM 4 inserts, the assembly enables quick indexable-insert changes and consistent cutting behaviour. These attributes together reduce unplanned stoppages and contribute to shorter cycle times in batch or prototype runs.

Stiffness, balance and secure clamping for consistent results

With a tool body mass of 0.712 kg, the holder provides the stiffness required to limit chatter during parting and grooving. The ISO 2525 designation and the connection to 4C‑R (110–150) bar sizes ensure compatibility with established tool carriers, enabling secure mounting and easy replacement in existing setups. The right-hand cutting direction aligns with common turning strategies and simplifies process planning. The combination of mass and standardised interfaces supports stable chip formation and predictable surface finish.

Application guidance and practical advantages on the shop floor

Intended for external grooving and parting operations, the holder suits operations that need a narrow kerf and dependable clamping. The specified maximum plunging depth of 20 mm is sufficient for many parting tasks without excessive tool extension. Using the recommended Korloy insert grade for the workpiece material will extend insert life and keep downtimes low. For machine setup, keeping overhang minimal and verifying correct insert seating and clamping torque will preserve tool life and maintain cutting precision. The design favours quick insert swaps and straightforward stock removal strategies for high-repeatability production.
