A20R PWLNL Boring Bar – PWLN for WNMG 0604, Left‑hand, Internal Coolant (Teknik Makina)

The A20R PWLNL is a left‑hand boring bar designed for turning operations with WNMG 0604 indexable inserts, providing stable support and coolant feed directly to the cutting edge

• Left‑hand orientation for specific turning tasks
• Internal coolant to the cutting edge
• 20 mm shank for secure clamping

Engineered performance for demanding turning operations

The holder is engineered to combine rigidity and accessibility for medium‑duty turning. The 20 mm shank and 25 mm diameter provide a compact but stiff support, reducing vibration when paired with WNMG 0604 inserts. The 95° cutting angle directs forces to a stable contact area so that the insert seat experiences minimal deflection; this improves surface finish and extends insert life. The result is predictable machining behaviour that supports consistent throughput in small to mid‑sized workshops.

Stable clamping and predictable chip flow

A precise clamp geometry and stable clamping ensure secure retention of the indexable insert, while the integrated internal coolant delivers lubricant and cooling directly to the tool–workpiece interface. This targeted coolant supply reduces heat build‑up, lowers tool wear and helps control chips during interrupted cuts. For setups where left‑hand cutting is required, this configuration supports effective chip evacuation and reduces secondary manual cleaning, increasing net productive time per shift.

Designed for efficiency and straightforward maintenance

With a 200 mm overall length and 40 mm cutting height, the bar balances reach and stiffness for many lathe applications. The compact mass (approx. 0.471 kg) simplifies tool changes and inventory handling. Maintenance is kept simple because the geometry matches common WNMG 0604 grades, enabling quick insert swaps without special adapters. Fewer tool changes and longer insert life translate into lower cost per finished part and reduced machine idle time.

Practical guidance for selection and set‑up

Select the A20R PWLNL when a left‑hand holder is required and when WNMG 0604 inserts are the preferred cutting grade for the job. Check machine turret clearance and ensure coolant lines are routed to feed the internal channel. When uncertainty remains about fitment or material suitability, the technical team can advise on insert grade, coolant pressure and optimal cutting parameters to match the application and workpiece material.

FAQ

What insert size is recommended for this holder?
The holder is specified for WNMG 0604 indexable inserts; this size matches the seat geometry and cutting height of the A20R PWLNL.

Is internal coolant supplied through the tool?
Yes. The A20R PWLNL features internal coolant to deliver coolant directly to the cutting zone, improving tool life and chip control.

Can this bar be used on standard turret lathes?
The bar is suitable for turret lathes that accept a 20 mm shank and left‑hand holders; verify turret clearance for the 200 mm overall length before mounting.

What is the cutting direction and why does it matter?
This product is designed for left‑hand cutting direction. Correct orientation is essential to ensure proper chip flow and secure clamping during turning.
