Boring bar S40U DCLNR – DCLN for CN-- indexable inserts, 50 mm diameter (Teknik Makina)

A Boring bar S40U DCLNR designed for right-hand turning applications, compatible with CN--1606 indexable inserts and specified for ISO S40U DCLNR toolholders

• S40U DCLNR ISO designation
• 50 mm diameter for high rigidity
• 350 mm overall length
• Compatible with CN--1606 indexable inserts

Stable machining through increased stiffness and predictable tool behaviour

The S40U DCLNR geometry offers a 50 mm diameter combined with a 40 mm shank, which increases bending stiffness and reduces vibration during cuts. This configuration helps maintain dimensional accuracy on long-reach operations where deflection is a risk. The 95° cutting angle supports stable chip flow for common turning tasks; the reduced tendency to chatter results in more consistent surface finishes and fewer reworks. The bar’s mass (approx. 3.55 kg) has been considered in the design to balance rigidity and handling without compromising toolholder integrity.

Fast setup and standardised insert replacement to save production time

Workflows are streamlined by the use of standard CN--1606 inserts, enabling quick, repeatable indexable insert changes and reducing machine downtime. The tool follows the ISO S40U DCLNR specification for installation into compatible toolholders, and the clamping reference 16 clarifies the intended clamp interface. Because insert replacement is straightforward, consumable costs are controlled and process reproducibility is improved. The combination of a standardised holder fit and indexable tips supports efficient maintenance cycles in high-mix production environments.

Practical reach and handling for workshop integration

With a 350 mm overall length, the bar provides the reach required for many internal and external boring tasks while retaining enough cross-section to limit deflection. The right-hand cutting orientation is suited to standard lathe setups and is compatible with common turning strategies. Tool life and part quality are supported by the bar’s geometry rather than by specialised coatings or materials, which means predictable behaviour across routine machining operations. The design is aimed at machinists and production engineers seeking a robust, standardised boring solution that integrates easily into existing tool inventories.
