Vollbohrer U166TM — Indexable insert drill, Ø 28 mm, 84 mm cutting length (Teknik Makina)

The Vollbohrer U166TM is a purpose‑built indexable insert drill body designed for industrial metalworking where predictable hole quality and quick insert replacement are required

• Ø 28 mm cutting diameter
• 25 mm shank diameter
• 84 mm cutting length
• Compatible with Korloy WCM‑0503 inserts

Greater rigidity for consistent hole quality

The drill body is engineered around a 25 mm shank, which increases stiffness in the holder and reduces vibration during penetration. Greater rigidity directly translates into improved runout control and more consistent bore tolerances, especially on medium‑diameter holes. With a 28 mm nominal diameter and an 84 mm cutting length, the geometry balances access and stability to deliver repeatable results when set up with the correct spindle speeds and feeds. This combination supports productive batch runs and lowers scrap rates through mechanical stability and controlled chip formation.

Minimise tooling cost with indexable inserts

Designed for use with Korloy WCM‑0503 indexable inserts, this drill body separates the cutting edge from the tool body so that only the insert needs replacing after wear. The result is a lower cost per hole and shorter downtime compared with solid‑tool regrinds. Insert technology also enables rapid selection of grades and geometries for different materials and surface finishes; changing the insert adapts the same body to diverse jobs, which supports lean inventory and faster response to mixed production demands.

Simple integration and predictable handling

Compact dimensions — 168 mm overall length and a 56 mm effective shank length — make the body straightforward to mount in standard toolholders while keeping overhang modest for reduced deflection. The unit weight of 0.576 kg gives a sense of balance in spindle change routines and transport between stations. These measured dimensions help in calculating effective reach and in selecting appropriate holder clamping to maintain concentricity, so the tool becomes an easy component of existing toolpacks and machining strategies.

FAQ

Which indexable inserts fit this drill body?
The drill body accepts Korloy WCM‑0503 indexable inserts as specified for the Teknik Makina U166TM

What are the key dimensions to check for holder compatibility?
Check the 25 mm shank diameter, 56 mm shank length and 168 mm overall length to ensure correct clamping and minimal overhang for the U166TM

What is the effective cutting length and hole diameter?
The tool provides an 84 mm cutting length for a nominal hole diameter of 28 mm

Can the drill body be used for different materials?
Material suitability depends on the selected insert grade and cutting parameters; the U166TM functions as a carrier for appropriate Korloy WCM‑0503 inserts chosen for the specific workpiece material

How does the indexable concept affect running costs?
Using replaceable inserts with the U166TM reduces the cost per cutting edge compared with solid regrinds and shortens maintenance time because only the worn insert is changed
