Internal corner turning tool DIN 4974 (ISO 9) — 10 x 10 mm, carbide P25/P30, right-hand

The Internal corner turning tool DIN 4974 (ISO 9) is a purpose-built internal profiling tool fitted with diamond-ground carbide inserts for machining radii and small internal corners in bores from 18 mm.

• Carbide P25/P30 inserts
• Cross-section 10 x 10 mm
• Right-hand cutting orientation
• Minimum bore Ø 18 mm

Precision and repeatability for internal finishing

The tool is designed to deliver consistent internal radii and corner profiles thanks to diamond-ground carbide inserts in P25/P30 grade. These inserts are mounted on a robust steel shank, which stabilises the cutting geometry and reduces chatter at typical cutting speeds. For shops that demand reproducible results, the combination of a defined 10 x 10 mm cross-section and a standardised holder interface ensures predictable engagement with the workpiece, minimizing rework and inspection effort. The DIN 4974 (ISO 9) conformity provides a verifiable basis for integration into established machining processes.

Compatibility with restricted bores and right-hand operations

Engineered for internal operations, the tool requires a minimum bore diameter of 18 mm, which makes it suitable for small to medium internal profiles in components. The right-hand cutting direction and the 150 mm overall length support deep internal approaches while keeping the tool overhang manageable. For operators less familiar with bore constraints, "minimum bore Ø" refers to the smallest inside diameter where the tool can be introduced without interference; this metric is critical when selecting tooling for assemblies with internal features.

Material performance and practical benefits

Manufactured from carbide, the cutting inserts combine hardness and wear resistance for sustained edge life during finishing passes. The choice of P25/P30 grades balances toughness and abrasion resistance for common steels and alloyed materials. In practical terms, this means longer intervals between insert changes and predictable surface finishes, which contributes directly to process economy. Where a polished edge or tight dimensional tolerance is required, the diamond-ground geometry aids in achieving a smoother running surface and reduced burr formation.

Integration into workshop workflows and quality assurance

The tool’s standardised geometry and DIN compliance facilitate quick mounting and replacement within modular tool holders, supporting lean tooling setups. Traceability is simplified by the SKU and product labelling for inventory control. For purchasers seeking reliability, the combination of tried-and-tested carbide grades and a steel shank with precision-mounted inserts reduces the risk of premature wear or tool failure during internal turning operations, thereby supporting steady production output and consistent part quality.

FAQ

What minimum bore diameter is required for use?
The tool requires a minimum bore Ø of 18 mm; the Internal corner turning tool must be introduced only into bores meeting or exceeding this diameter to avoid interference.

Which carbide grades are fitted to the inserts?
Fitted inserts are P25/P30 grade carbide, chosen to provide a balance of toughness and wear resistance suitable for common steel and alloy applications.

Is the tool suitable for deep internal profiling?
Yes, the 150 mm overall length and the steel shank design permit internal profiling at moderate depths while maintaining stability for accurate finishes.

What does DIN 4974 (ISO 9) mean for the user?
DIN 4974 (ISO 9) indicates a standardised tool geometry and mounting interface, which simplifies replacement, holder compatibility and process documentation for the internal corner turning tool.

How many pieces are supplied per package?
The product is supplied in a packaging unit of 5 pieces, allowing for quick inventory replenishment and predictable usage planning.
