TGTT R2020K AH1007 Turning indexable insert — PVD-coated carbide, 30° clearance — Tungaloy

TGTT R2020K AH1007 is an ISO-standard turning indexable insert designed for external and internal turning, offering a 60° triangle form and a single-sided chipbreaker for controlled chip formation

• PVD-coated carbide grade AH1007
• Triangle insert, 60° included angle
• 30° clearance angle ensures sharp cutting edge
• Cylindrical hole with single-sided countersink

Precise, ISO-compatible solution for turning workflows

The insert is an ISO-standard turning insert, designed to match holders by form, clearance angle, tolerance class, fastening method, size and thickness. This compatibility principle reduces setup time and avoids mismatches that cause vibration or poor surface finish. With a defined 30° clearance angle and the 60° triangle geometry, the component provides a predictable seating and cutting orientation, which leads to reproducible cutting conditions and reduced scrap rates. Where process reliability is paramount, the combination of standardised form and exact tolerances supports faster job changes and consistent part accuracy.

Durable cutting edge and improved process security

The AH1007 grade is a PVD-coated carbide developed for turning applications that demand a sharp cutting edge plus resistance to both wear and chipping. The PVD coating increases thermal stability at the cutting zone and improves adhesive wear resistance, while the cemented carbide substrate maintains edge strength. This results in longer effective tool life and fewer unplanned interruptions. For shops seeking to balance economy and performance, the wear properties allow higher metal removal rates with maintained surface quality, translating into measurable productivity gains.

Geometry and clamping designed for stable machining

The triangular form with a 60° included angle and an R2 nose size gives rigidity at the cutting point, reducing deflection on long overhangs or interrupted cuts. The insert thickness of 2.38 mm supports secure clamping forces, and the cylindrical hole with a single-sided countersink (40°–60°) ensures reliable fixation in compatible toolholders. The single-sided chipbreaker is tailored to produce controllable chips for both external and internal turning, lowering the risk of entanglement and aiding automated chip evacuation. Such geometry choices improve surface finish and dimensional consistency under variable cutting conditions.

Productivity advantages and application guidance

When used for turning tasks, the combination of AH1007 grade and the single-sided chipbreaker offers a dependable mix of wear resistance and fracture toughness, suitable for a broad range of steels and general turning operations. The insert supports stable cutting parameters and can be integrated into production cycles where repeatability is essential. For best results, match the insert to a holder that accommodates the ISO code R2020K and the triangular form, select cutting data aligned with the material being machined, and consider coolant strategy to extend edge life in high-speed or heavy-duty applications.

FAQ

What materials is this insert suitable for?
The TGTT R2020K AH1007 insert is a PVD-coated carbide grade designed for general turning; its wear resistance and edge strength make it suitable for a wide range of steels and common turning applications.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this triangular insert promotes controlled chip formation during turning, reducing the risk of long, stringy chips and improving chip evacuation in both external and internal operations.

Which holder geometry is required for this insert?
The insert follows ISO conventions for triangular turning inserts; compatibility depends on holder form, clearance angle and the R2020K ISO code. Use holders that accept a triangle 60° insert with a cylindrical locating hole and single-sided countersink.

What are the main dimensions to check when selecting this insert?
Key dimensions include the thickness (2.38 mm), included angle (60°), clearance angle (30°) and the R2 nose size; verify these against the toolholder specifications.

Is the insert suitable for interrupted cuts?
The triangular geometry and the robust AH1007 grade offer good stability and edge strength for many interrupted cutting scenarios, though feed and depth of cut should be adjusted to application specifics.
