A16R PWLNL boring bar – PWLN for WNMG indexable inserts, 16 mm shank, internal coolant (Teknik Makina)

The Bohrstange A16R PWLNL is a left-hand boring bar engineered for WNMG 0604 indexable inserts, intended for stable external turning and accurate insert positioning in production environments

• Left-hand cutting direction
• Internal coolant supply
• 16 mm shank diameter
• Compatible with WNMG 0604 inserts

Precision and vibration control for repeatable turning

The A16R PWLNL is built around a compact, rigid shaft that gives stable cutting even in interrupted cuts. A 16 mm shank combined with the tool's 20 mm outer diameter and a 95° cutting angle reduces bending moments and improves concentricity when paired with appropriate toolholders. The design focuses on repeatability: secure clamping for WNMG 0604 inserts minimises axial play, which translates into consistent diameters and improved surface finish. For workflows where small deviations are critical, the robust geometry contributes directly to process reliability and fewer rework cycles.

Cooler cutting zones and better chip evacuation

Integrated internal coolant (through-tool cooling) channels coolant directly to the cutting edge, lowering temperature at the insert contact zone and improving cutting-edge life. This targeted coolant delivery assists in chip control and helps maintain stable cutting conditions, especially during longer runs. Reduced heat generation leads to steadier cutting forces and, in many cases, longer intervals between insert changes. For shops aiming to raise overall machining uptime, the coolant feature is a practical performance enhancer that supports higher productivity without complex adaptations.

Compatibility, handling and workshop advantages

The bar accepts WNMG 0604 indexable inserts and is specified as ISO A16R PWLNL, simplifying selection and ensuring interchangeability with standard inserts. The left-hand cutting orientation is suited to setups that require reverse feed direction or specific lathe configurations; the clamp designation 06 clarifies which clamping systems are compatible. With an overall length of 200 mm, a 40 mm cutting height and a net weight of 0.326 kg, the tool is compact to mount and balances well in moderate-duty turning applications. The modular nature of indexable tooling reduces spare-part diversity while keeping setup changes quick and predictable.

FAQ

How does the internal coolant affect tool life and surface finish?
Internal coolant delivers fluid directly to the cutting edge, reducing heat and aiding chip evacuation; the A16R PWLNL’s built-in coolant channel helps maintain cutting-edge integrity and can improve surface finish and insert longevity.

Which inserts and clamp size are compatible with this boring bar?
The bar is made for WNMG 0604 indexable inserts and uses clamp designation 06, allowing standard clamping systems for secure insert retention with the A16R PWLNL (Teknik Makina, SKU AP388TM).

What does left-hand cutting mean in practice?
Left-hand cutting indicates that the cutting action proceeds against a leftward feed direction; the A16R PWLNL is intended for setups where the tool feeds from right to left relative to the workpiece rotation.

Can this tool be used for heavy roughing or is it for finishing?
The boring bar’s rigid 16 mm shank and 20 mm diameter provide good stiffness for many external turning tasks; suitability for roughing or finishing depends on insert grade and machine capability rather than the bar alone.
