CKJNL 2525 clamping holder — CKJN for KNUX indexable inserts, left-hand, 25 × 25 mm — Teknik Makina

CKJN for KNUX indexable inserts is an engineered clamping holder for left-hand turning, designed to hold KNUX 1604 indexable inserts with reliable rigidity and repeatable positioning.

• Left-hand cutting orientation
• Compatible with KNUX 1604 inserts
• Robust M6 locking screw for secure clamping
• 25 × 25 mm holder body, 150 mm overall length

Rigid design for repeatable machining accuracy

The CKJNL 2525 clamping holder is built around a compact 25 × 25 mm cross-section and a 150 mm overall length, offering a balance of stiffness and accessibility for common turning tasks. The combination of a M6 locking screw and the BK028 clamp prong secures the insert seat to minimise micro-movement during cuts. This rigidity translates into improved dimensional repeatability and reduced tool-change adjustments, which supports higher first-pass yield in production settings.

Optimised geometry for left-hand turning with KNUX inserts

Designed specifically for KNUX 1604 indexable inserts, the toolholder presents a cutting angle of 93° and a cutting head width of 30 mm with a cut height of 35 mm. The left-hand orientation means the insert geometry and holder seating are matched for left-handed operations, preventing misalignment and ensuring consistent chip flow. For workshops standardising on KNUX inserts, this reduces setup time and simplifies inventory by matching holder geometry to the insert form.

Practical assembly and maintenance for workshop efficiency

Assembly and routine maintenance are straightforward: the clamp plate is secured with an M3x10 screw to the TA046 shim plate while the primary locking is provided by the M6 screw. A 3 Allen key is indicated for the relevant fastenings. These standardised fastenings make insert replacement and re-tightening quick, reducing machine downtime. The holder’s modest mass (approximately 0.75 kg) keeps handling safe while providing sufficient mass to dampen vibration during many operations.

Application benefits and production-level reliability

With a 25 mm holder width and 25 mm height, the holder suits constrained toolpost configurations while offering a cutting head profile that balances reach and stiffness. The toolholder’s compatibility with KNUX 1604 inserts and its secure clamping arrangement support repeatable surface finish and tolerance control in batch turning. For production environments seeking predictable tool performance, this holder reduces variables that cause scrap or rework and integrates straightforwardly into existing insert-based tooling systems.
