Internal turning tool DIN 4973 (ISO 8) – 25 x 25 mm, Carbide P25/P30 – Werner Wilke

The Internal turning tool DIN 4973 (ISO 8) is a right‑hand tool designed for precise internal turning in bores from 43 mm, featuring diamond‑ground carbide cutting plates mounted on a robust steel shank.

• Diamond‑ground carbide cutting plates
• Carbide grade P25/P30
• 25 x 25 mm cross‑section
• Right‑hand cutting, DIN 4973 compliant

Consistent cutting performance from a proven carbide grade

This internal turning tool is built around carbide P25/P30, a grade selected for sustained wear resistance and repeatable edge geometry. The diamond‑ground inserts provide a precisely finished cutting edge that maintains form over repeated cycles, reducing the need for frequent regrinding. Conformity with DIN 4973 (ISO 8) ensures dimensional consistency and interchangeability with compatible tool holders, which simplifies tool inventory management and supports predictable machining results in series production.

Rigidity and reach that improve surface finish and stability

A 25 x 25 mm cross‑section combined with a 300 mm overall length offers a well balanced compromise between reach and stiffness. The larger cross‑section increases resistance to deflection during internal cuts, helping to reduce chatter and deliver a more consistent surface finish. For operations where tolerance stability matters, the tool’s geometry translates directly into fewer rejects and less dressing time for downstream processes, supporting tighter production tolerances without complex setup changes.

Easy integration and reliable mounting for workshop workflows

Designed with a steel shank fitted with diamond‑ground carbide plates, the assembly plugs into standard DIN 4973 compatible clamping systems, allowing straightforward adoption into existing toolposts and turret holders. The right‑hand cutting orientation suits conventional internal turning cycles and can be used for profiling and facing inside bores. The robust construction reduces accidental insert movement, which helps to save setup time and minimises unexpected interruptions in repetitive machining tasks.

Practical suitability and operational notes

The tool requires a minimum bore diameter of 43 mm, which defines the lower limit for safe engagement of the cutting plates. Because the cutting plates are diamond‑ground, the geometry is already optimised for consistent chip formation and predictable wear patterns; this eases tool life monitoring and replacement scheduling. For optimal results, ensure correct clamping torque and holder alignment in accordance with DIN 4973 guidelines to retain the tool’s dimensional stability and cutting performance over extended runs.
