A25S PCLNL AP350TM – PCLN Boring Bar for CNMG Indexable Inserts, Internal Coolant

A25S PCLNL AP350TM is a left-hand PCLN-style boring bar designed for turning operations with CNMG 1204 indexable inserts, offering internal coolant delivery for enhanced tool life and process stability

• Internal coolant delivery
• For CNMG 1204 inserts
• Left-hand cutting orientation
• 32 mm overall diameter

Coolant where it matters for longer tool life and better finishes

The integrated internal coolant channel directs cutting fluid precisely to the cutter edge, reducing heat at the cutting zone and flushing swarf away from the insert seat. This focused cooling lowers thermal wear and supports a more consistent edge condition, which in turn improves surface finish and reduces rework. The result is a measurable improvement in productivity and a reduction in tooling cost per component when machining in continuous production environments.

Fast set-up and reliable compatibility for efficient changeovers

Built around a PCLN pocket for standard CNMG 1204 indexable inserts and identified by the A25S PCLNL ISO designation, the toolholder simplifies insert mounting and alignment. The clear interface between holder and insert shortens set-up time and minimises adjustment, supporting faster tool changes on turning centres. This compatibility ensures predictable cutting geometry and repeatable results across batches and operators.

Stable geometry tuned for left-hand turning tasks

The holder’s left-hand cutting orientation and robust body — 32 mm overall diameter with a 25 mm shank — create a rigid assembly that resists vibration during offset cutting. A cutting angle of 95° and a cutting height of 50 mm contribute to secure clamping of the insert and consistent chip formation. Together these features provide process stability that allows shops to maintain higher feed rates while preserving dimensional accuracy.

Engineered for workshop and production use with clear supply assurance

Designed for repeatable performance in commercial workshops and industrial turning lines, this boring bar balances rigidity and accessibility for frequent use. The modest mass and overall length of 250 mm provide reach without excess overhang, supporting tighter tolerances in bore and face work.

FAQ

What insert type does this holder accept?
The AP350TM is designed for CNMG 1204 indexable inserts and uses a PCLN-style pocket to ensure secure seating and repeatable positioning.

Is the coolant internal or external?
Internal coolant is provided; the internal coolant channel delivers fluid directly to the cutting edge for improved cooling and chip evacuation.

Which cutting direction is this tool designed for?
This boring bar has a left-hand cutting orientation, intended for left-hand turning applications.

What are the key dimensions for machine setup?
Key dimensions: overall length 250 mm, diameter 32 mm, shank diameter 25 mm; these figures support stability and toolholder fitting.

Can the AP350TM be used on CNC lathes for production runs?
Yes, the AP350TM is engineered for production use with features that support repeatable geometry, active coolant delivery and reduced set-up time
