Boring bar K259TM — SDUC holder for DC-- indexable inserts, Ø20 mm × 150 mm (Teknik Makina)

Boring bar K259TM is a compact SDUC-style holder designed for DC-- 11T3 indexable inserts, intended for precision turning and light boring tasks in CNC and turret applications

• SDUC holder for DC-- 11T3 indexable inserts
• Diameter 20 mm for improved rigidity
• Overall length 150 mm, ISO S16M SDUCL
• Torx clamping screw M3.5×8.5, key T15

Greater process stability from a compact design

The holder’s 20 mm diameter and 150 mm overall length provide increased stiffness compared with slimmer alternatives, which helps to reduce vibration and improve surface finish during turning operations. For setups where tool overhang is restricted, the compact profile supports consistent cutting conditions and repeatable results. The holder is identified by the ISO S16M SDUCL designation, ensuring compatibility with common turret and toolpost interfaces and simplifying tool-life planning in production workflows.

Secure, straightforward insert clamping for fast changeovers

Insertion and removal of the cutting tip is handled by a Torx screw M3.5×8.5 secured with a T15 key, allowing reliable mechanical clamping without specialised fixtures. The simple clamping mechanism reduces changeover time and minimises the risk of incorrect seating, which supports higher machine utilisation and predictable part quality. The holder accepts DC-- 11T3 indexable inserts, a widely used geometry that enables shops to keep stock of versatile cutting edges for finishing and light roughing tasks.

Suited to precision workshops and small-batch production

Designed for CNC workshops and toolrooms that prioritise predictable performance, the tool holder is ideal where compact tool setups and fast insert replacement are needed. The modest mass (approx. 0.246 kg) keeps turret load low and assists rapid acceleration on modern machines, while the SDUC configuration aligns with established indexable-insert systems. This combination of features makes the holder a practical choice for milling and turning centres handling frequent tool changes and mixed-series production.

Simple integration and reliable supply chain

With the clear ISO designation and standard clamping hardware, the holder fits into existing tool inventories with minimal adaptation. The robust mechanical design supports frequent insert changes with little maintenance beyond routine inspection of the screw and seating face. Supplied by Teknik Makina under SKU K259TM, the component is intended as a straightforward, serviceable element in a larger tooling strategy, helping to reduce procurement complexity and downtime.
