A25S PDUNR Boring Bar – 93° for DNMG 1506, Internal Coolant | Teknik Makina

A25S PDUNR is a right-hand boring bar designed for precision internal turning with DNMG 1506 indexable inserts, offering coolant feed to support reliable chip evacuation and consistent cutting performance

• 93° cutting angle for reduced radial load
• Internal coolant for targeted cooling and chip control
• Compatible with DNMG 1506 indexable inserts
• 25 mm shank diameter for enhanced rigidity

Greater radial stability for precise bores

The combination of a 25 mm shank and a 32 mm head diameter produces high rigidity during bore-making, which reduces deflection and improves dimensional accuracy. A rigid toolholder minimises chatter and enables reproducible results when finishing bores or performing medium-depth turning. This stability is particularly relevant for components where concentricity and surface finish are critical, and it supports faster, more reliable set-ups on conventional and CNC lathes.

Purpose-built for DNMG 1506 indexable inserts

Engineered to accept DNMG 1506 inserts, the holder features a 93° cutting angle that lowers radial cutting forces and promotes predictable chip flow. The bar is specified for right-hand cutting and is compatible with standard DNMG insert geometries; the ISO designation A25S PDUNR describes the mounting and orientation for indexed turning. Using widely available inserts keeps tooling flexible and reduces inventory complexity while allowing quick insert changes to restore cutting performance.

Internal coolant for longer tool life and controlled chips

Integrated internal coolant directs fluid close to the cutting edge, which reduces thermal loading on the insert and improves chip breaking in continuous cuts. Targeted cooling helps maintain edge integrity and can extend insert life, decreasing the frequency of tool changes and downtime. In operations with constrained chip spaces or where efficient evacuation is required, the coolant-fed holder gives a clear process advantage for consistent cycle times and lower secondary finishing effort.

Practical workshop benefits and applications

With an overall length of 250 mm, a cutting height of 50 mm and a weight of 0.9 kg, the bar balances reach with manageable handling for routine lathe tasks. The right-hand cutting direction and robust clamping diameter make it suitable for internal turning and medium-duty boring in production and repair shops. Specified as SKU AP300TM, the tool supports quick integration into existing tooling systems and contributes to predictable machining cycles, reducing rejects and improving throughput.
