Indexable Insert Drill U791TM — Teknik Cutting Tools — 31 mm, 155 mm cutting length

The Indexable insert drill U791TM is an industrial-grade holemaking tool designed for deep and stable drilling operations in machining centres and heavy-duty lathes, compatible with Korloy WCM‑06T3 inserts.

• 31 mm cutting diameter for medium holes
• 155 mm cutting length for deeper bore operations
• Compatible with Korloy WCM‑06T3 inserts
• 32 mm shank for high rigidity

Maximise productivity with a replaceable-insert solution

The indexable design combines the cost benefits of replaceable inserts with the performance of a solid drilling system. By using Korloy WCM‑06T3 inserts, the tool reduces downtime for regrinding and lowers per-hole costs while maintaining consistent cutting quality. The 155 mm cutting length permits deeper bores without compromising stability, and indexed tips allow quick replacement to restore cutting geometry and extend tool life.

Rigidity and stability engineered for repeatable precision

A firm connection is achieved through the 32 mm shank, providing increased torsional stiffness and better vibration damping compared with smaller holders. The result is improved hole roundness and repeatability across production batches. The tool’s overall length of 216 mm and well-proportioned shank-to-cutting-length ratio support secure clamping and predictable chip evacuation, which is essential for maintaining tolerances in serial manufacturing.

Practical benefits for workshop and production planners

The combination of an indexable concept and a substantial cutting length supports flexible process planning: inserts can be selected for specific materials, and worn tips replaced without discarding the whole toolbody. The design improves cost-efficiency for medium-run and long-run production, enabling quicker tool changes and predictable maintenance schedules — a clear advantage for operations seeking steady throughput and lower tooling overhead.

Compatibility and application overview for material choices

This drilling solution accepts Korloy turning inserts WCM‑06T3, simplifying procurement and compatibility with established insert stocks. With a 31 mm diameter and 155 mm cutting length, the tool is suitable for conventional steels and a range of common workshop materials when combined with appropriate insert grades and cutting data. The robust construction and measured mass support controlled feeds and speeds for improved surface finish and dimensional integrity.
