Wilke internal corner turning tool DIN 4974 (ISO 9) — 12 x 12 mm, Carbide P25/P30, right-hand

The Wilke internal corner turning tool DIN 4974 (ISO 9) is a right-hand internal corner tool designed for precision profiling in confined bores and fitted with diamond-ground carbide cutting plates on a steel shank

• Carbide P25/P30 tip for consistent wear resistance
• Conforms to DIN 4974 (ISO 9) standard
• 12 x 12 mm square shank for stable clamping
• Smallest bore Ø 21 mm for tight internal corners

Consistent cutting quality for tight internal radii

The tool delivers repeatable edge geometry through its diamond-ground carbide cutting plates, ensuring uniform chip formation and surface finish in internal profiles. Compliance with DIN 4974 (ISO 9) guarantees dimensional and manufacturing consistency, which reduces process variation on serial components. The carbide grade P25/P30 is selected for a balance of toughness and hardness, making the insert suitable for interrupted cuts and medium-duty internal turning tasks. This results in fewer tool changes and predictable tool life, supporting efficient machining cycles.

Secure clamping and straightforward set-up

A 12 x 12 mm square cross-section provides positive locating surfaces in standard tool holders, enabling rapid clamping and minimising deflection during turning operations. The steel shank, fitted with precision-mounted carbide plates, simplifies insert replacement and alignment on the holder. With a total length of 180 mm, the tool offers a practical reach for small-to-medium bores while keeping overhang low to reduce chatter. Mentioning the right-hand cutting direction clarifies orientation at set-up and avoids mounting errors.

Practical benefits for workshop productivity

Using a carbide-tipped internal corner tool reduces rework and sanding by producing a cleaner internal corner straight off the machine. The specified smallest bore Ø 21 mm makes this tool a solid choice for compact internal features where larger tools cannot access. Less manual finishing and fewer rejected parts translate into measurable time savings on the shop floor. For customers seeking reliable machining performance, the tool supports steady production rates and simplified inventory management thanks to its standardised geometry.
