A25S PDUNL Boring Bar — PDUN for DNMG Indexable Inserts, Internal Coolant (Teknik Makina)

A PDUN for DNMG Indexable Inserts designed as a left-hand boring bar with integrated coolant feed for secure insert clamping and reliable chip control during turning operations

• Compatible with DNMG 1506 indexable inserts
• Internal coolant supply for reliable chip evacuation
• ISO A25S PDUNL left-hand orientation
• 25 mm shank, 250 mm total length

Stable coolant and secure insert clamping for consistent cutting

The A25S PDUNL holder features an integrated internal coolant channel that directs coolant straight to the cutting zone, improving heat control and promoting cleaner chip breakage. Combined with compatibility for DNMG 1506 indexable inserts and a 93° cutting angle, this geometry is oriented for stable material removal when a left-hand cut is required. These characteristics reduce thermal load on the insert and help maintain dimensional accuracy across serial runs, delivering reproducible cutting performance without unnecessary downtime.

Robust shank and compact length for rigid setup

Built with a 25 mm shank and 250 mm total length, the tool holder balances accessibility and rigidity to limit deflection in common turning setups. The 50 mm cutting height and modest 0.9 kg mass aid quick clamping and stable rotation while keeping the assembly easy to handle during changeover. The compact dimensions translate into improved vibration damping and repeatable tool positioning, which in turn supports tighter tolerances and less rework in medium‑ to high‑volume machining.

Application focus: efficient indexable insert turning in production

Specifically aimed at indexable insert turning workflows, this left‑hand tool holder supports fast insert indexing and straightforward tool maintenance. Use of indexable insert systems keeps running costs predictable by allowing individual edge changes rather than full‑tool replacement, while the integrated coolant and reliable clamping reduce the risk of unexpected tool failure. For machining lines where consistent cycle times and minimal intervention are priorities, the PDUN configuration offers a pragmatic balance between serviceability and cutting stability.
