Vollbohrer U316TM – Indexable insert drill body, 21 mm diameter (Teknik Makina)

the Vollbohrer U316TM is an indexable insert drill body designed for medium-depth holemaking in production and workshop environments

• Diameter 21 mm for standard hole sizes
• Compatible with Taegutec SOMT 0703 inserts
• 63 mm cutting length for deeper bores
• 25 mm shank for secure clamping

Precision and productivity combined for repeatable holemaking

The drill body delivers consistent hole quality through its rigid design and defined cutting length. With a 21 mm diameter and 63 mm of cutting length, the tool reduces the need for multiple operations by enabling single-pass holemaking where material and process allow. The use of indexable inserts means cutting edges can be replaced rapidly, lowering downtime and keeping cycle times short while maintaining dimensional stability across production runs.

Cost-efficient machining through replaceable inserts

A key economic advantage is the compatibility with Taegutec SOMT 0703 inserts: worn edges are exchanged instead of replacing the entire tool body, which reduces tooling costs and stock complexity. The combination of an exchangeable insert system and a 25 mm shank for secure clamping helps to preserve spindle life and maintain constant run-out, translating into fewer rejected parts and a more predictable cost per hole.

Simple integration with common spindle setups

The tool’s 141 mm overall length and defined shank geometry allow straightforward mounting in standard holders and adaptors. The compact yet rigid proportions minimise deflection during cutting, which supports tighter tolerances and better surface finishes. For shops upgrading from solid drills, the indexable system provides a rapid return on investment where frequent edge changes or interrupted cuts occur.

Practical handling and maintenance on the shop floor

At roughly 0.377 kg, the body is easy to handle during insert changes and set-up, without compromising stability when clamped. The clear insert designation and matching manufacturer make re-orders and inventory management simple. Routine maintenance is limited to checking screw torque and insert condition, which keeps maintenance intervals short and predictable.

FAQ

What materials can be machined with this drill body?
The Vollbohrer U316TM from Teknik Makina accepts Taegutec SOMT 0703 inserts and is suitable for general-purpose machining; selection of the correct insert grade determines suitability for steel, stainless steel or cast materials.

Which insert type fits the U316TM?
This drill body uses SOMT 0703 indexable inserts by Taegutec; using the recommended insert grade for the application ensures the best balance between tool life and surface finish for the U316TM (SKU U316TM).

How deep can holes be drilled in a single pass?
With a 63 mm cutting length, the tool allows efficient single-pass drilling within that effective cutting zone; deeper bores require staged operations or through-tool coolant solutions depending on material and process.

Is the shank compatible with standard toolholders?
The 25 mm shank diameter provides secure clamping in common holders; the design of the U316TM supports stable mounting for consistent concentricity and repeatability.
