AP314TM Boring bar — PDUN for DNMG indexable inserts, internal coolant, left-hand

A AP314TM boring bar designed for turning with DNMG indexable inserts, offering left-hand cutting orientation and integrated coolant for controlled chip evacuation.

• Internal coolant for controlled chip flow
• Compatible with DNMG 1506 indexable inserts
• Left-hand cutting for specific lathe set-ups
• Robust 40 mm shaft reduces deflection

Precision and rigidity for consistent turning results

The design combines a 40 mm shaft with a 300 mm overall length to deliver improved stiffness and repeatability in external turning operations. Reduced bending and vibration are achieved by the larger shaft diameter, which helps maintain tolerances across longer passes; this results in fewer rejects and more predictable finish quality. The tool is identified by the ISO designation A40T PDUNL, a standard reference that ensures correct selection and interchangeability in production environments.

Controlled chip flow and improved surface finish

Integrated internal coolant directs cutting fluid to the insert seat and cutting edge, lowering thermal load and assisting chip evacuation. With a cutting angle 93° and a 55 mm cutting height, the geometry supports stable engagement with DNMG 1506 indexable inserts, improving surface integrity and tool life. Internal coolant reduces the risk of built-up edge and enables higher sustained cutting parameters, so machining cycles can be optimised without compromising component quality.

Workshop-ready design that supports steady production

The bar is specified for indexable turning with the PDUN geometry and is supplied with the technical attributes that fit industrial toolrooms: for DNMG 1506 indexable inserts, left-hand cutting orientation and a compact weight of 1.79 kg for straightforward handling. The nominal diameter is 50 mm, while the shaft and mounting details follow the A40T standard, simplifying integration with compatible toolholders (clamp designation: 15). Choice of a standardised ISO type and clear compatibility reduces downtime when inserts are changed and supports reliable supply chains in series production.

FAQ

What insert type fits this boring bar?
The AP314TM is designed for DNMG 1506 indexable inserts and accepts the PDUN insert geometry specified in the technical data.

Is the coolant internal or external?
This boring bar features internal coolant, which is delivered through the bar to the insert seat to aid cooling and chip evacuation.

Can the bar be used for right-hand turning?
The AP314TM is manufactured for left-hand cutting; right-hand operations require the corresponding right-hand variant.

What is the ISO designation and why is it relevant?
The ISO designation A40T PDUNL identifies the bar’s shank and head geometry, simplifying matching with compatible toolholders and ensuring correct installation in production settings.

Is the A40T shank compatible with standard holders?
The A40T PDUNL profile is a commonly used shank form and is compatible with holders designed for A40T shanks; verify clamping details (clamp designation: 15) against the holder specification before use.
