TGTT R2020K AH1004 – TGTTR2020K ISO turning insert, PVD‑coated carbide, 30° relief, triangular

The TGTTR2020K is an ISO‑standard triangular indexable insert for external and internal turning, offering a sharp cutting edge and a single‑sided chipbreaker for stable material removal.

• PVD-coated carbide for wear resistance
• ISO-standard triangular insert
• 30° relief for secure cutting
• Cylindrical hole with countersink 40°–60°

Consistent cutting performance for production turning

The insert’s PVD-coated carbide substrate provides sustained wear resistance and edge integrity, helping to maintain process security in series production. The PVD layer reduces flank wear and supports a stable cutting edge under interrupted or continuous cuts, which translates into longer effective tool life and fewer interruptions on the shopfloor. For operations that demand repeatable surface quality, the combination of a sharp geometry and a coated carbide grade reduces variability between parts and shortens the need for frequent regrinds.

Designed for reliable clamping and quick tool changes

Built to the ISO-standard form, the indexable plate is compatible where shape, relief angle, tolerance class, clamping method, size and thickness match the holder. The cylindrical hole with a 40°–60° countersink secures consistent seating and torque transfer, while the triangular outline ensures simple orientation in standard external holders and boring bars. Using the correct holder and clamping kit avoids slippage and preserves the insert’s cutting edge, so set‑up time is minimised and runout is reduced.

Geometry and chip control that suit process-secure turning

The insert features a 30° relief and a 60° included angle that balance cutting-edge strength with accessibility for precision turning. The single-sided chipbreaker promotes predictable chip formation for many turning tasks and reduces the risk of chip accumulation in the cutting zone. With a compact contact area and a 2.38 mm thickness, the plate gives a solid bearing surface and edge support; the R2 designation defines a small nose radius that is suitable for fine finishing passes or controlled light cuts where dimensional accuracy is critical.

System approach: how the insert fits into the tooling setup

This indexable plate is part of a system that includes the appropriate external holder or boring bar, a backing/locating pad and clamping set plus replacement fasteners. Specifying the correct tolerance class, holder form and screw combination completes a secure mounting solution and protects the insert from chipping caused by unstable support. Planning tool inventory with matching inserts and holders reduces downtime and simplifies reconditioning cycles, supporting higher throughput and consistent part quality.

FAQ

What applications suit this insert best?
The AH1004‑graded TGTTR2020K insert is intended for general external and internal turning where a sharp cutting edge and high process security are required; it is suitable for finishing and light to medium turning tasks.

How does the PVD coating affect performance?
The PVD-coated carbide surface on the TGTTR2020K reduces flank wear and enhances edge life, improving consistency in production runs and supporting longer tool intervals.

What holder features are necessary for correct use?
A compatible ISO external holder or boring bar with the correct form, clamping set and screw size is required to match the TGTTR2020K’s geometry, clearance angle and hole/countersink arrangement for secure seating.

Which geometry details are important during setup?
Pay attention to the 30° relief, 60° included angle, 2.38 mm thickness and R2 nose radius; these determine accessible cutting conditions, stiffness and the achievable surface finish.
