125mm Turning Holder CKJN for KNUX Indexable Inserts, left, 20mm x 20mm - Teknik Makina

Turning Holder (Klemmhalter) — CKJN for KNUX Indexable Inserts by Teknik Makina

The Turning Holder is a precision clamping solution for left-hand turning, designed to accept KNUX 1604 indexable inserts and deliver stable machining in demanding workshop environments.

• Turning Holder CKJN for KNUX 1604 inserts
• Robust clamping design with M6 locking screw
• Compact: 20 mm Shank Width, 125 mm Overall Length
• Cutting Head Width 27 mm for stable machining
• Left-Hand Cutting Direction, 93° Cutting Angle

Secure clamping for higher cutting forces

The holder features a deliberately engineered clamping arrangement that secures the insert reliably under load. The M6 locking screw and compatible BK028 clamping wedge ensure consistent seat pressure, which reduces vibration and improves tool life. This design leads to more reliable chip formation and repeatable results during prolonged turning cycles.

Compact dimensions that increase rigidity

With a 20 mm Shank Width and 125 mm Overall Length, the tool body minimises overhang for enhanced stiffness. The Cutting Head Width 27 mm and Cutting Height 32 mm focus support where it matters most, translating into better surface finish and dimensional stability. The 93° Cutting Angle combined with the Left-Hand orientation is suited for standard turning setups that require precise radial engagement.

Fast insert changes and broad compatibility

Compatibility with KNUX 1604 indexable inserts and the ISO designation CKJNL 2020 simplifies tooling logistics and reduces downtime. Indexable inserts allow quick replacement without regrinding, and the included 3 Allen key interface supports straightforward assembly. For shops switching between insert grades, this holder provides a hassle-free platform for rapid tooling adjustments.

Built for workshop efficiency and series production

Designed for small-batch and serial turning operations, this clamping holder supports consistent cycle times and simplified setups. The clearly defined interfaces — TA046 U Plate, M3x10 U Plate Screw, and accessible locking hardware — reduce setup complexity. Operators and production planners benefit from predictable performance and easier tooling standardisation across machines.
