S25S DCLNL boring bar — DCLN for CN-- indexable inserts, left‑hand cutting (Teknik Makina)

S25S DCLNL boring bar is a left‑hand internal turning tool engineered for CN-- 1204 indexable inserts, offering extended reach and consistent chip control in medium‑duty turning operations

• Left‑hand cutting for internal turning
• Fits CN-- 1204 indexable inserts
• 25 mm shank diameter for stability
• 250 mm overall length for extended reach

Accurate geometry for predictable results

The S25S DCLNL is designed with a 95° cutting angle and a defined cutting height of 50 mm, which together enable consistent engagement of the insert and predictable material removal. These geometric parameters reduce deflection during interrupted cuts and help maintain repeatable bore tolerances. In practical terms, the combination of left‑hand cutting geometry and the DCLN head form means the tool is optimised for internal turning where chip flow and tool orientation must be controlled. For operations that require dependable bore quality, this configuration supports stable tool life and process reliability.

Robust shank and reach for vibration control

With a 25 mm shank diameter and 250 mm overall length, the bar balances reach and stiffness to limit chatter in deep bores. The solid shank is the main contributor to stability, while the external diameter of 32 mm provides clearance and support where required. The bar’s mass of 0.964 kg contributes to dampening minor vibrations without excess weight that would compromise turret dynamics. For workshops looking to extend effective cutting depth without swapping to larger tooling, this boring bar offers a pragmatic compromise between rigidity and accessibility.

Simple insert management and quick set‑up

This boring bar is specified for CN-- 1204 indexable inserts, a widely used insert family that simplifies inventory and changeover. Indexable inserts provide repeatable cutting edges, and the DCLN pocket allows secure clamping and consistent positioning of the insert. For users unfamiliar with exchangeable‑edge tooling: an indexable insert is a replaceable cutting tip which is clamped into the toolholder; once an edge is worn it is indexed or replaced, restoring cutting performance without regrinding. The ISO designation S25S DCLNL identifies the shank and head form for correct turret and holder matching.

Practical benefits in the workshop

When fitted into a turret with the appropriate 25 mm holder clearance, the tool delivers stable internal turning with reduced downtime for insert changes. The left‑hand orientation should be selected where the tool approach and spindle rotation require that direction for optimal cutting. The compact balance of diameter, shank and length makes the bar suitable for many conventional lathes and CNC turning centres where medium‑reach internal operations are common. Clear numerical specifications aid planning: shank, length, diameter and cutting angle are provided so setup and collision checks can be performed before cutting.
