Precision and consistency for repetitive drilling

The U780TM is engineered to deliver repeatable bore quality in mid- to high-volume machining. The combination of a 20 mm bore diameter and a 100 mm cutting length allows a single tool body to reach deeper workpieces without secondary extensions, which reduces setup complexity and cumulative run-out. The fixed shank geometry and mass distribution contribute to consistent tool engagement; this translates into predictable cycle times and reduced scrap rates in serial production.

Robust clamping and axial stability

A 25 mm shank diameter supports solid clamping in standard tool holders and quick-change systems. Greater shank stiffness diminishes vibration and deflection, improving hole roundness and surface finish. This mechanical stability benefits both medium-duty finishing and roughing passes, allowing fewer corrective operations and more efficient use of machining centres. The design focuses on secure retention to keep insert positioning accurate under the axial loads typical of deep drilling.

Insert system that limits downtime

Compatibility with WCm-0402 indexable inserts from Korloy means cutting edges can be replaced rapidly without reclamping the whole tool body. Indexable inserts reduce regrind cycles and lower tooling cost per hole by shifting the wear to inexpensive, replaceable tips. The modularity of the insert concept supports fast tool changes during shift work and facilitates inventory management of cutting grades tailored to materials and cutting conditions.

Manufacturer and application clarity for procurement

Supplied by Teknik Makina, the U780TM suits workshop environments that prioritise throughput and predictable maintenance. The tool body’s measured weight of 0.421 kg and standard connection dimensions allow straightforward integration into existing setups. For procurement and planning, the combination of insert availability, measurable geometry and established mounting standards makes the U780TM a practical choice for manufacturers seeking a balance of serviceability and machining reach.

FAQ

What materials is this tool body suitable for? The U780TM indexable drill body accepts WCm-0402 inserts (Korloy) and is suitable for a wide range of common workshop materials; insert grade selection should be matched to the workpiece material for optimal performance.

How does the insert system affect maintenance? Using WCm-0402 indexable inserts on the U780TM reduces maintenance time because worn cutting edges are replaced quickly, avoiding the need to replace or regrind the entire tool body.

Which holder or chuck is required for secure mounting? The tool body’s 25 mm shank diameter is compatible with standard tool holders and clamping systems; check the machine’s tooling interface to confirm holder type and clamping method.

Is the U780TM suitable for deep-hole drilling applications? Yes; the 100 mm cutting length and 179 mm overall length give extended reach suitable for deeper bores while maintaining stability for serial machining.

Where can technical data sheets or CAD files be obtained? Technical documentation associated with the U780TM (file IDs provided) can be requested through Metav Werkzeuge’s sales or technical department for integration and verification.
