Internal corner turning tool Wilke (DIN 4974 / ISO 9) – 20 x 20 mm, carbide P25/P30

The internal corner turning tool Wilke is designed for precise internal radius machining, featuring a steel shank fitted with diamond-ground carbide inserts for use in bores from 34 mm upward.

• Steel shank with carbide inserts
• Carbide grade P25/P30 for long life
• Suitable for bores from 34 mm

Precision and productivity in confined bores

The tool combines a rigid 20 x 20 mm cross-section with an overall length of 250 mm, offering stable turning performance in internal applications. The carbide P25/P30 cutting edges provide a balance between toughness and wear resistance, which reduces microchipping and maintains dimensional accuracy over longer production runs. Conforming to DIN 4974 (ISO 9) ensures interchangeability with established holders and setups, simplifying tool replacement and machine setup times. These characteristics translate into fewer interruptions and a measurable productivity gain on the turning centre.

Versatile material capability and predictable results

Equipped with diamond-ground inserts on a steel shank, the turning holder is suitable for a wide range of internal finishing and profiling tasks. The right-hand cutting direction is optimised for conventional internal turning operations. The tool’s geometry and carbide grade make it appropriate for steels and typical engineering alloys where consistent corner radii and surface quality are required. By specifying this turning tool, machinists benefit from predictable tool life and repeatable part quality, reducing rework and securing process stability in small-diameter bores.

Reliability, serviceability and procurement confidence

Maintenance is straightforward: replace the diamond-ground carbide inserts to restore cutting performance without changing the whole holder, which keeps downtime and operating costs low. Supplied in a packaging unit of 5, this tool is suitable for workshops that require quick replenishment. Sourced from established manufacturing practice and kept in stock via Metav’s European distribution, the turning tool supports steady supply chains and fast dispatch. For buyers seeking a dependable internal turning solution, this tool offers the technical conformity and supply reliability needed for continuous production.
