Indexable Drill Body U139TM – 37 mm Ø, 170 mm overall length (Teknik Makina)

An indexable drill body engineered for precision holemaking in CNC and turning centres, the Indexable Drill Body U139TM is designed to accept Korloy-compatible inserts for efficient production drilling.

• High-stability 32 mm shank
• Ø 37 mm cutting diameter
• 74 mm effective cutting length
• Compatible with Korloy WCM-06T3 inserts

Consistent hole quality through stable design

The main advantage of this indexable drill body is its stable shank geometry and balanced mass, which together reduce vibration and promote repeatable hole quality. With a 32 mm shank and an overall length of 170 mm, the tool offers a favourable rigidity-to-reach ratio for medium-deep holes. The reduced runout achieved by the precise shank and clamping interface improves tool life of the inserts and lowers scrap rates, supporting a smoother production flow and predictable cycle times.

Productivity gains from effective cutting length and insert system

Equipped with a 74 mm cutting length, the tool allows extended engagement without sacrificing stiffness. The use of the WCM-06T3 insert system—compatible with Korloy grade inserts—enables fast index changes and consistent cutting geometry. This combination reduces machining downtime compared with regrind cycles and supports efficient chip evacuation when paired with suitable coolant or through-tool lubrication. The modular insert approach also simplifies inventory management by standardising insert types across similar operations.

Practical handling and mounting benefits

The tool’s 32 mm shank and 58 mm shank length provide straightforward mounting in standard drill holders or hydraulic chucks; the nominal weight of 0.875 kg keeps handling safe while minimising spindle load during fast tool changes. Clear identification of the insert seat and compatibility data streamlines toolroom setup and reduces trial runs. For operations migrating from solid drills to indexable systems, this body offers an economical route to higher productivity with lower per-hole tooling costs.
