Boring Bar AP340TM — PCLN holder for CNMG indexable inserts with internal coolant

The Boring Bar AP340TM is a right-hand PCLn-style toolholder engineered for precision internal turning with CNMG 1204 indexable inserts, suited to confined bores and finishing passes in production and toolroom environments

• Right-hand PCLN holder
• Internal coolant for chip control
• Compatible with CNMG 1204 inserts
• Shank Ø 25 mm, length 250 mm

Stable holder geometry for precise internal turning

The design provides a rigid mounting platform that reduces vibration during internal operations, improving surface finish and reproducibility. With the ISO designation A25S PCLNR the toolholder matches common clamping systems and ensures predictable alignment with standard tool posts. The shank Ø25 mm and compact overall form translate into a reduced overhang, which lowers deflection and supports tighter tolerances on turned bores. This structural stability is particularly relevant where consistent concentricity and repeatable diameters are required.

Controlled coolant flow to extend insert life and clear chips

Built-in internal coolant directs lubricant and coolant directly to the cutting zone, aiding chip evacuation and heat dissipation. Targeted coolant delivery reduces thermal loads on the insert, which can extend insert life and allow steadier cutting parameters. The holder’s 95° approach angle facilitates effective chip flow for CNMG geometry, meaning fewer interruptions and more consistent cycle times in series production. These features combine to increase process efficiency and reduce unplanned insert changes.

Straightforward integration with CNMG indexable systems

Compatibility with CNMG 1204 inserts makes the toolholder suitable for a wide range of turning tasks where indexable carbide inserts are standard. The PCLN mounting style ensures secure clamping of inserts and straightforward index changes, keeping downtime to a minimum. The right-hand cutting orientation is designed for conventional lathe setups; the product’s nominal data such as cutting height 50 mm and overall length 250 mm support clear planning for fixture and turret arrangements. The holder is delivered ready for integration into common turning tool assemblies.

FAQ

Which insert type fits this toolholder?
The AP340TM accepts CNMG 1204 indexable inserts; the PCLN clamping style of the boring bar is designed specifically for that insert format and grade choices.

Is coolant supplied through the bar?
Yes, the holder features internal coolant, directing fluid to the cutting edge to support chip control and thermal management during machining.

What are the key dimensions for fixture planning?
Nominal dimensions include a shank diameter of 25 mm, an overall length of 250 mm and a cutting height of 50 mm, which inform turret clearance and overhang calculations.

How does the ISO designation affect compatibility?
The A25S PCLNR ISO designation indicates the standardised holder geometry, facilitating interchange with compatible tool posts and clamping systems when using Teknik Makina components such as the AP340TM
