S40U DDUNR Boring Bar – 40 mm shank, 350 mm overall length (Teknik Cutting Tools)

A S40U DDUNR boring bar engineered for right-hand turning operations with DN-- 1506 indexable inserts, designed to deliver stable machining in medium to heavy-duty workshop environments

• 40 mm shank for secure clamping
• Compatible with DN-- 1506 inserts
• 93° cutting angle for stable control
• 350 mm overall length and robust mass

Consistent cutting performance for precision turning

The ISO-designated S40U DDUNR bar couples a 40 mm shank with a measured 93° cutting angle, which together reduce deflection and improve surface finish during off-centre or extended-reach turning. The combination of shank diameter and geometry provides a predictable tool behaviour under load, making cycle times more reliable and lowering the risk of rework. This configuration supports steady chip evacuation and stable cutting forces, resulting in fewer interruptions in production.

Faster set-up through standardised insert compatibility

Compatibility with DN-- 1506 indexable inserts simplifies tooling logistics and shortens changeover times. The tool’s 60 mm cutting height matches common insert sizes for this family, enabling quick, repeatable seating of the insert and consistent tool projection. For workshops managing multiple tool holders, the standardised insert format reduces the number of spare parts required and streamlines inventory, thereby improving throughput without compromising cutting performance.

Robust design that integrates with existing toolholders

With a 350 mm overall length and a mass of 3.336 kg, this boring bar is balanced for rigidity while allowing sufficient reach for internal and external applications where access is limited. The right-hand cutting orientation and the tool’s ISO designation ensure compatibility with standard holders and clamping systems. The combination of measured dimensions and standard fitting reduces setup uncertainty and supports consistent quality across batches.

FAQ

Which insert type fits this boring bar?
The S40U DDUNR boring bar accepts DN-- 1506 indexable inserts; the tool geometry is matched to that insert family for secure seating and consistent cutting height.

Is the bar suitable for extended-reach turning?
The 350 mm overall length and 40 mm shank provide a balance of reach and rigidity, so the bar is appropriate for applications requiring greater access while maintaining stability.

What is the cutting direction of the tool?
This bar has a right-hand cutting direction; the orientation is indicated by the tool’s ISO designation and is suitable for standard right-hand turning operations.

How will the weight affect machining stability?
At 3.336 kg, the mass of the tool contributes to stability and vibration damping during cutting, which helps to maintain surface quality and reduce the likelihood of chatter.
