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

The Internal turning tool DIN 4973 (ISO 8) is a right-hand internal turning tool designed for precision machining of bores from 14 mm, fitted with diamond-ground carbide cutting plates on a steel shank

• Diamond-ground carbide inserts
• Suitable for bores from 14 mm
• Right-hand cutting direction
• Overall length 125 mm

Consistent finish and chip control for small-bore machining

The tool delivers a predictable cutting result through the use of diamond-ground carbide cutting plates in P25/P30 grades, which combine wear resistance with sufficient toughness for general steel machining. Fitted as a right-hand internal turning holder, the design supports controlled chip formation and a smooth surface finish even in restricted working spaces. The specification to the DIN 4973 (ISO 8) interface ensures compatibility with standard clamping systems, reducing set-up time and improving process reliability.

Stiffness and stability for repeatable performance

A steel shank with a compact 8 x 8 cross-section and an overall length of 125 mm offers a balance between accessibility and rigidity. The short overhang and square cross-section reduce vibration and deflection, which translates into longer insert life and fewer reworks. The construction supports stable cutting parameters in internal turning operations and helps maintain concentricity when machining smaller diameters, contributing to predictable cycle times and lower scrap rates.

Practical integration and workshop benefits

Specified for use in bores from minimum bore 14 mm, this internal turning solution is supplied in packaging unit 5, allowing for batch replenishment and straightforward inventory control. The diamond-ground inserts simplify tool preparation and produce consistent cutting edges without additional regrinding. For workshops seeking a compact, standardised boring holder that dovetails with existing toolholders and collet systems, the implement provides an efficient route to precision internal turning while minimising process variability.
