Internal turning tool DIN 4973 (ISO 8) – 20 x 20 mm, HM P25/P30, right-hand (Werner Wilke)

An internal turning tool for compact bores, fitted with diamond-ground carbide cutting plates and designed for dependable, repeatable internal machining in workshops and light industrial production.

• Carbide P25/P30 for robust cutting
• 20 x 20 mm cross-section for compact bores
• Right-hand cutting for standard turning
• Suitable for minimum bore Ø 34 mm

Accurate bore turning with compact stability

The 20 x 20 mm cross-section provides a stable contact profile for internal operations, reducing vibration and improving surface finish in confined spaces. Compliant with DIN 4973 (ISO 8), this design supports consistent centring and measured tool positioning, which is particularly beneficial when machining shafts, bushings or stepped bores. By combining a compact shank with rigid construction, the tool simplifies setup and maintains cutting geometry over runs, contributing to predictable cycle times and less rework in serial production.

Durable carbide for consistent performance

Equipped with carbide inserts in grades P25 and P30, the tool delivers a balance of wear resistance and toughness suited to a range of steels and alloyed materials. The diamond-ground finish on the cutting plates reduces built-up edge and improves chip control, which extends insert life and keeps surface integrity high. A steel shank carrying the inserts ensures secure clamping and repeatable orientation, translating into lower tooling costs per part and reliable performance across medium-duty turning tasks.

Production-ready handling and integration

Designed as a right-hand internal turning solution with a total length of 250 mm, the tool fits common turret and toolpost arrangements while allowing access into bores down to the minimum bore Ø 34 mm. Supplied in packaging unit: 5, it is suitable for replenishment in small workshops or for stocking at the production line. The configuration and dimensions make the tool straightforward to insert in standard holders, and its geometry supports predictable chip flow and easy post-process inspection—factors that accelerate downstream quality control and reduce machine downtime.
