• For CNMG 1204 indexable inserts
• 20 mm shank diameter, 200 mm overall length
• No internal coolant required

Stable cutting performance for left-hand turning

The PCLN geometry combined with compatibility for CNMG 1204 inserts provides a balance of rigidity and accessibility for internal and external facing operations. The 20 mm shank offers a rigid mounting that reduces chatter and enhances surface finish, while the slightly larger 24 mm diameter at the cutting head improves stability. With a 95° cutting angle, the tool is suited to precise finishing cuts where dimensional accuracy matters. These characteristics translate into fewer reworks and steadier cycle times on production runs.

Fast insert changes and secure clamping

Specified to ISO as S20R PCLNR, the bar accepts standard CNMG indexable inserts, enabling quick insert replacement and compatibility with common insert grades. The standardised interface reduces setup time and inventory complexity, because compatible inserts and toolholders are widely available. The secure insert pocket and robust seat design ensure repeatable clamping, which supports consistent tool life and predictable machining results for batch work and single-piece manufacturing alike.

Practical design to keep workshops productive

At a 200 mm overall length and weighing 0.54 kg, the tool is compact enough for tight set-ups while providing sufficient reach for many turning tasks. The combination of shaft and head dimensions allows use with a wide range of holders designed for a 20 mm shank, reducing the need for special adaptors. The resulting ease of integration and minimal maintenance requirements help to lower machine downtime and simplify tool management in busy shops.

Dry-ready operation for specific process requirements

Designed without internal coolant, the bar is intended for processes that use external cooling, dry machining strategies, or where internal coolant is unnecessary or undesirable. The left-hand cutting orientation matches machines and operations that require counter-direction cutting, keeping process flows consistent. Choosing a coolant-free tool can simplify machine plumbing and reduce potential points of failure, while still delivering reliable cutting performance when paired with the appropriate insert grade.

FAQ

Is this bar compatible with standard CNMG insert grades?
Yes. The boring bar is designed for CNMG 1204 indexable inserts and works with standard CNMG grades suited to the machining task.

Can the bar be used where internal coolant is required?
No. This model is supplied without internal coolant, so operations requiring through-tool coolant need an alternative tool with internal coolant provision.

What does the ISO designation S20R PCLNR tell me?
The S20R PCLNR ISO code indicates the shank and insert seat geometry, ensuring compatibility with holders and inserts that match that specification.

Is the 20 mm shank suitable for common toolholders?
Yes. The 20 mm shank conforms to common holder sizes, allowing straightforward installation in standard toolholders used in many workshops.

Does the left-hand orientation affect setup on the lathe?
Left-hand cutting direction means the tool is intended for counter-direction turning operations; check machine and programme orientation to ensure correct mounting of the bar.
