CKJN for KNUX Indexable Inserts — CKJNR 2020 toolholder, 93° right‑hand (Teknik Makina)

The CKJN for KNUX Indexable Inserts is a right‑hand turning holder engineered for shoulder operations with KNUX 1604 inserts, offering a standard ISO shank and a rigid 93° head geometry

• Right‑hand holder, 93° cutting angle
• Fits KNUX 1604 indexable inserts
• Head width 27 mm, body width 20 mm
• Total length 125 mm, weight 0.434 kg

Accurate shoulder turning thanks to a 93° geometry

The 93° head geometry provides a clear benefit for precise shoulder cuts and close‑up turning operations. With a defined cutting angle of 93° and a right‑hand orientation, the holder supports controlled engagement of the insert, which reduces deflection during interruptive cuts and improves dimensional repeatability. The specified cutting height of 32 mm contributes to stable chip formation and predictable tool behaviour, helping to maintain surface finish and tolerance in serial production.

Standardised shank and compact design for fast set‑up

Adopting the CKJNR 2020 ISO designation means the holder aligns with common toolpost standards; the measured 20 x 20 mm shank (body width and holder height both 20 mm) enables straightforward machine set‑up and rapid changeover. The compact total length of 125 mm and 27 mm head width allow flexible positioning in confined tool stations while preserving the mechanical rigidity required for repeatable turning tasks. These dimensions simplify inventory management and reduce the need for bespoke fixturing on smaller lathes.

Compatibility with KNUX inserts and robustness in production

Designed for KNUX 1604 indexable inserts, the holder accepts the standard insert form for shoulder and finishing operations; the ISO interface ensures correct seating and orientation, which shortens tool change time and lowers rework risk. The holder’s mass of 0.434 kg supports stable dynamic behaviour without adding unnecessary load to the turret. The right‑hand cutting direction is optimised for conventional lathe orientations and common turning cycles on production lines.

Practical benefits for workshop efficiency

Using an ISO‑conforming holder reduces setup complexity: standardised dimensions and a defined shank profile mean fewer adapter requirements and quicker commissioning across multiple machines. The combination of rigid geometry and compatibility with widely used indexable inserts delivers tangible productivity gains — less vibration, fewer adjustments and more consistent part quality. For operations seeking predictable tool life and reduced downtime, integrating this holder into an organised tooling strategy is a pragmatic step.

FAQ

What insert type fits this holder?
The holder is designed for KNUX 1604 indexable inserts and seats them in the ISO interface specified by the CKJNR 2020 designation.

Is this a right‑hand or left‑hand toolholder?
This is a right‑hand holder with a 93° cutting angle, suited to conventional right‑hand turning operations.

What are the key dimensions to check for machine compatibility?
Important dimensions include the 20 x 20 mm shank profile, 125 mm total length and 27 mm head width; these determine fitment in standard toolposts and turret stations.

Can the holder be used for heavy interrupted cuts?
The rigid 93° geometry and specified cutting height promote stability for many shoulder operations; suitability for heavy interruptions depends on machine power and insert grade selection.
