CGWT R0040- AH967 — CGWTR0040- AH967 Tungaloy Turning Insert (ISO, PVD carbide)

A CGWTR0040- AH967 turning insert engineered for reliable external and internal turning, offering a rhombic R0 shape with a single-sided chipbreaker and ISO compatibility for standard holders

• PVD-coated carbide grade AH967
• ISO-standard rhombic R0 geometry
• 30° clearance angle for sharp cutting
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance and wear resistance for turning operations

The combination of a PVD coating and a carbide substrate provides elevated wear resistance and a stable cutting edge under continuous use. The coated grade AH967 is designed to resist flank and crater wear, which reduces the need for frequent index changes and helps maintain dimensional consistency across production batches. This results in fewer interruptions during turning and a measurable increase in process reliability when machining both external and internal profiles. The rhombic geometry contributes to a predictable cutting direction and secure seat in ISO tool holders.

Clear compatibility rules and safe clamping for predictable results

Compatibility with toolholders depends on shape, clearance angle, tolerance class, attachment method, size and thickness; the ISO designation R0040- clarifies fitment for standard clamping systems. The insert features a cylindrical hole with a one-sided countersink (40°–60°), which improves seat alignment and torque distribution during fastening. The 30° relief angle supports a sharp cutting edge for light to medium turning passes while reducing radial forces. Selecting the correct holder and clamping hardware ensures repeatable mounting and preserves the insert’s edge life.

Productivity benefits and application scope explained

The single-sided chipbreaker is optimised to control chips for many turning tasks while the rhombic R0 form permits access to confined features and internal contours. This insert is well suited to standard turning applications where a balance of edge sharpness and process security is required. The ISO-standard form factor simplifies inventory management and interchangeability, enabling straightforward replacement and minimising machine downtime. Overall, the geometry and grade support both batch production and small-series machining with predictable output quality.

Handling, inspection and economical use for shopfloor efficiency

Routine inspection of insert edges and correct torque on clamping screws prolongs service life and prevents unexpected edge failure. Store spare inserts in their original packaging to avoid chipping the cutting edges and label inventory by ISO code and grade for rapid selection. When worn, replace the indexable insert rather than attempting regrinding; the consistent performance of the coated carbide grade AH967 reduces cumulative operational costs and contributes to stable surface finish and dimensional control.

FAQ

What materials is this insert suited for?
The CGWTR0040- AH967 insert is a PVD-coated carbide tool designed for general turning tasks; material-specific suitability depends on workpiece characteristics and cutting data rather than the insert alone.

How does the AH967 grade affect tool life?
The AH967 coating enhances wear resistance and edge stability, so the insert typically maintains cutting performance longer than uncoated grades under comparable conditions.

Which holders fit this insert?
Compatibility is determined by ISO form, clearance angle, tolerance class, attachment and thickness; the R0040- ISO code indicates standard holders accepting a rhombic R0 insert with a 4.76 mm thickness.

Is the chip control suitable for internal turning?
The single-sided chipbreaker provides controlled chip formation suitable for many internal turning tasks, especially where space is limited and chip evacuation is required.

What does the cylindrical hole with countersink provide?
The cylindrical hole with a 40°–60° one-sided countersink improves seating accuracy and distributes clamping forces, supporting repeatable mounting and secure fastening.
