K411TM Boring bar S25S DDUNR — Ø32 mm body, shank Ø25 mm, right-hand cut (Teknik Makina)

A K411TM boring bar designed for indexable DN-- inserts, suited to right-hand turning tasks in CNC lathes and metal‑working shops

• Right-hand cutting direction
• Ø 32 mm body diameter
• Shank Ø 25 mm for secure clamping
• Compatible with DN--1504 inserts

Greater rigidity for consistent bore quality

The robust Ø32 mm body combined with a shank Ø25 mm provides increased stiffness compared with slimmer tool bars, which reduces chatter and improves surface finish. The 250 mm overall length is balanced for common lathe setups, while the 93° cutting angle helps maintain tool engagement and precise material removal. These design choices translate into fewer reworks and steadier cycle times on production runs.

Fast insert changes and predictable costs

Compatible with DN--1504 indexable inserts and specified as S25S DDUNR, the holder accepts standard replaceable plates for efficient changeovers. With a cutting height 50 mm and a dedicated insert pocket, the system enables quick indexing and repeatable seating without complex adjustment. The use of indexable inserts reduces consumable costs per hole and simplifies maintenance compared with solid tools.

Built for shop-floor productivity and machine compatibility

Optimised for CNC turning, the bar’s right-hand cut and measured mass of 0.958 kg support predictable cutting forces and steadier tool life. The 250 mm overall length and clear ISO designation make fixture planning straightforward, and the bar’s geometry reduces setup time by enabling reliable clamping. For operations requiring repeatable bore diameters and minimal set-up variance, this tooling option improves throughput without sacrificing precision.
