Consistent bore quality thanks to diamond-ground carbide

The combination of P25/P30 carbide and diamond-ground cutting plates provides a stable cutting edge and reduced vibration, which leads to consistent surface finishes in internal turning operations. The carbide grades cited ensure wear resistance under typical finishing feeds; the diamond-ground geometry stabilises chip formation and reduces the need for frequent edge dressing. For production environments where repeatable bore quality matters, this cutting arrangement supports predictable cycle times and fewer reworks.

Rigid geometry for stable internal machining

A 16 x 16 mm cross-section and a 210 mm overall length deliver the stiffness required for internal operations while permitting access into moderate-depth bores. The square shank profile resists torsion and bending under load, reducing chatter and preserving tool life. Compliance with DIN 4973 (ISO 8) ensures compatibility with standard tool holders and indexable setups, simplifying integration into existing turning centres without bespoke adapters.

Designed for restricted bores and right-hand turning

With a minimum bore diameter of 27 mm and a right-hand cutting orientation, the tool is tailored to internal facing, profiling and light boring tasks where access is limited. The right-hand cut direction suits standard spindle rotation and common turning strategies, providing intuitive tool paths for operators. This configuration is particularly useful for engineering workshops tackling internal machining on medium-sized components where tool access and reliable chip evacuation are critical.

Easy specification and workshop integration

The tool’s steel shank, fitted with diamond-ground carbide plates, allows straightforward replacement of inserts and predictable performance across batches. As a DIN-conforming internal turning tool, it fits established holders and clamping systems, reducing setup time. For procurement and planning, the item is supplied in packaging units of five, enabling stock control for small to medium production runs while maintaining traceability through the SKU and standard reference.

FAQ

What is the minimum bore diameter for this internal turning tool?
The tool requires a minimum bore diameter of 27 mm, so internal operations below this diameter are not recommended.

Which carbide grades are fitted to the cutting plates?
The inserts are P25/P30 carbide, diamond-ground for stable cutting edges and improved surface finish in internal turning.

Is this tool compatible with standard DIN holders?
Yes, the tool conforms to DIN 4973 (ISO 8) and is designed to fit standard compatible holders and clamping systems.

What is the cross-section and overall length of the shank?
The shank measures 16 x 16 mm in cross-section with an overall length of 210 mm, offering a balance of stiffness and reach.

Is the cutting orientation left- or right-hand?
This internal turning tool features a right-hand cutting orientation, suitable for conventional spindle rotation and turning strategies.
