Solid drill U788TM — 28 mm, 140 mm cutting length (Teknik Makina)

Solid drill U788TM for industrial indexable‑insert drilling, engineered for use with Korloy WCM‑0503 inserts in machining centres and heavy‑duty setups

• 28 mm cutting diameter
• 140 mm cutting length
• Shank Ø 25 mm, 56 mm shank length
• Compatible with Korloy WCM-0503 inserts

Improved cycle times through longer cutting reach

The tool’s 140 mm cutting length and 224 mm overall length deliver extended reach that reduces the need for intermediate tool changes during deep or stepped drilling operations. A longer cutting zone allows a single tool to complete more of the machining process, which improves throughput and reduces handling. The combination of a 28 mm cutting diameter and a substantial shank gives a predictable cutting geometry that helps maintain concentricity and reduces rework. Engineers and production planners will value the tool’s capacity to keep setups simple while maintaining process stability.

Rigidity and repeatability for demanding production

A shank Ø 25 mm with a 56 mm engagement length provides the mechanical stiffness required for consistent chip evacuation and lower runout in high‑speed or high‑feed operations. The tool’s mass of 0.742 kg contributes to its damping behaviour, helping to stabilise the cutting edge under load. Designed to accept Korloy WCM‑0503 indexable inserts, the assembly offers fast insert changes and repeatable cutting performance, which supports predictable cycle times and easier tool maintenance in a production environment. Where process reliability and repeatability are priorities, this configuration performs as a dependable option.

Integration, sourcing and confidence in supply

Supplied under Teknik Makina specification, this solid drilling solution has been engineered for compatibility with established insert geometries and is suitable for integration into CNC machining centres and industrial drilling rigs that accept indexable‑insert tooling. The tool body is intended as a modular element in an insert‑based system, enabling fast replacement of cutting edges without replacing the entire tool body. Metav Werkzeuge’s presence in Emmerich acts as a local quality filter for the European market, offering consistent availability and technical support for procurement decisions.
