Vollbohrer U403TM — Indexable-insert drill body with 14.5 mm diameter and 20 mm shank (Teknik Makina)

A Vollbohrer U403TM designed as a drill body for replaceable SOMT 0502 inserts, intended for efficient, repeatable holemaking in workshop and light-production environments.

*14.5 mm nominal diameter
*20 mm shank for stable clamping
*56 mm effective cutting length
*Compatible with SOMT 0502 inserts

Consistent, measurable hole accuracy for small-series production

The drill body delivers repeatable diameter control by combining a true shank interface with a defined cutting length, which reduces setup variability. With a 14.5 mm nominal diameter and a 20 mm shank, the component is engineered to transfer torque and minimise runout during drilling cycles. The 56 mm cutting length provides sufficient engagement for through-holes and shallow blind holes while keeping chip evacuation predictable. These measurable parameters support process stability and help maintain tolerances across batches, reducing scrap and rework.

Fast insert changes and clear compatibility reduce machine downtime

Designed for indexable inserts, the tool accepts SOMT 0502 plates and is compatible with inserts from Taegutec, which simplifies procurement and replacement. The insert-based concept separates cutting geometry from the body: worn cutting edges are replaced instead of the entire tool, cutting maintenance time and tooling costs. The body’s 50 mm holder length and standard 20 mm interface make it suitable for common drill holders and spindles, enabling quick changeovers without custom adaptors. This modularity benefits shops that alternate materials or run short production batches.

Robust design for workshop and on-machine applications

With an overall length of 128 mm and a low mass of 0.175 kg, the drill body balances rigidity and manoeuvrability. The compact geometry helps to reduce vibrating tendencies while maintaining sufficient stiffness for controlled machining. The construction is tailored to indexable-insert workflows, supporting a clear chip flow and stable seat for the insert seat. For engineers specifying tooling, the component offers a practical mix of durability and serviceability, making it suitable for maintenance, prototyping and serial production where consistent results are required.

FAQ

What insert type fits this drill body?
The drill body accepts SOMT 0502 indexable inserts; Teknik Makina’s U403TM is specified for that plate type and matches standard insert geometries.

Is the shank compatible with common toolholders?
Yes, the 20 mm shank is a common industrial interface and the U403TM is designed for stable clamping in standard drill holders.

Can the tool be used for both through-holes and blind holes?
The 56 mm cutting length on the U403TM makes it suitable for through-holes and for many shallow blind-hole applications, depending on the workpiece and holder setup.

Which insert manufacturer is recommended?
Taegutec inserts are recommended; the U403TM is compatible with Taegutec plates and the SOMT 0502 designation.

How does the tool help reduce machining costs?
By using replaceable inserts, the U403TM reduces tooling waste and downtime since only the insert is renewed at wear, not the entire body.
