Consistent left‑hand parting that improves process reliability

The left‑hand orientation supports machining strategies where chip flow and tool approach demand a counter‑direction setup; left‑hand cutting reduces interference on specific turning programmes and helps to maintain surface integrity during parting. The holder’s geometry is optimised for controlled cut‑off and groove creation, reducing unexpected deflection and enabling steady metal removal. This translates into fewer rejected parts and a more predictable production rhythm.

Compact clamping dimensions for repeatable set‑ups

With a clamping block of 25 x 25 mm and an overall length of 150 mm, the unit is designed for quick, repeatable mounting in standard tool posts. The modest mass of 0.727 kg contributes to a balanced assembly that resists vibration without imposing excessive load on the turret drive. A compact footprint speeds changeovers and simplifies fixture planning, supporting higher machine uptime and lower set‑up complexity for batch and single‑piece production alike.

Clear insert compatibility and practical machining limits

The holder accepts Korloy 4C MGM inserts (designation 4C MGM) and mates with shank types such as 4C‑L MGM, ensuring straightforward sourcing of cutting edges. The 4 mm cutting width is ideal for narrow groove and parting tasks, while the maximum plunge depth of 18 mm defines the safe working envelope for through‑cuts and partial grooving. Identified by ISO 2525, the clamping concept aligns with established standards for cutter seating and insert retention.

Robust design that integrates with existing turning cells

Manufactured to deliver stable insert clamping and repeatable positioning, the holder’s construction supports durable performance in workshop and production environments. The moderate overall length and standardised clamping face enable easy integration into CNC lathe tool turrets and quick‑change systems. Clear mechanical references and standard shank compatibility simplify toolroom logistics and reduce time spent on trial fits and adaptations.
