28mm Solid Drill Body 56mm Cutting Length 140mm Overall, 25mm Shank - Teknik Makina

Take advantage of a robust combination of 28 mm diameter, 56 mm effective cutting length and a compact 25 mm shank for stable, repeatable drilling operations; order the component directly via Metav Werkzeuge or consult our specialists for application-matched advice.

Vollbohrer U928TM — solid drill, 28 mm diameter · 140 mm overall length · Teknik Makina

The Vollbohrer U928TM is a solid drilling solution designed for indexable insert applications, combining a long overall length for deep-hole access with a short cutting length for controlled chip formation in serial production.

• 28 mm diameter for medium drilling
• 140 mm overall length for deep access
• 56 mm cutting length for controlled chip removal

High-performance drilling where repeatability matters

The drill body is engineered for consistent results in production environments: its 28 mm diameter and 56 mm cutting length deliver a balance between rigidity and chip evacuation, while the 140 mm overall length enables access to deeper features without sacrificing stability. The modular nature of the tool means cutting performance is defined by the chosen indexable insert, so tool life and surface finish can be adapted to process requirements. This configuration supports efficient cycle times and helps reduce rework in series machining.

Secure clamping and compatibility to reduce setup time

With a 25 mm shank for standard rigid chucks and a matching 56 mm shank length, the tool ensures reliable clamping and concentricity in high-torque operations. The drill body is specified for SPMG 0904 inserts and is compatible with inserts from Taegutec and YG-1, enabling straightforward sourcing of cutting grades and geometries. Using established insert standards simplifies inventory management and minimises downtime when inserts are exchanged.

Clear workshop advantages and practical handling

Weighing approximately 0.5 kg, the component is easy to handle during tool changeovers yet remains heavy enough to feel robust, supporting safe installation and removal. The indexable approach allows economical replacement of worn cutting edges instead of entire tools, improving cost efficiency per part and lowering waste. Where insert selection is matched to material and speed, the tool body supports controlled chip flow and predictable surface quality, making it suitable for repeated production cycles.

FAQ

What insert type fits this drill body?
The drill body accepts SPMG 0904 indexable inserts; compatible manufacturers listed are Taegutec and YG-1 for a wide choice of grades and geometries.

Is the body suitable for deep-hole drilling?
Yes, the 140 mm overall length provides access for deeper holes while the 56 mm cutting length keeps chip control and rigidity suitable for many production tasks.

Which clamping system is recommended?
A chuck or holder that secures a 25 mm shank with sufficient axial support is recommended to maintain concentricity and repeatability with the U928TM.

Can the cutting performance be adapted for different materials?
Cutting performance depends on the selected insert grade and geometry; using SPMG 0904 inserts from Taegutec or YG-1 allows adaptation to a broad range of materials and cutting conditions.

What is the workshop benefit of an indexable drill body?
An indexable design reduces tooling cost per cutting edge, simplifies maintenance and shortens downtime because only inserts are replaced, not the entire tool body.
