TPGT 130302 GT720 triangular turning insert for finishing — Tungaloy

TPGT130302 GT720 Tungaloy insert for ISO‑standard turning, designed for finishing and light external and internal turning of steel

• ISO‑standard triangular insert, 3.18 mm thick
• GT720 cermet for finishing and light turning
• 0.2 mm corner radius for fine surface finish
• Cylindrical hole with 40°–60° countersink

Precision finishing for turning operations

The TPGT130302 GT720 insert is engineered for finishing and light turning where surface finish and dimensional accuracy matter. The GT720 cermet grade combines high hot hardness with a wear‑resistant cutting edge to promote even wear and consistent part quality over longer tool life. The small 0.2 mm corner radius reduces tool marks while allowing stable engagement at low feeds, delivering measurable improvements in Ra and repeatability compared with larger radii. For shops moving from roughing to finishing, the insert offers a reliable step‑up in product consistency without complex setup changes.

Reliable clamping and holder compatibility for repeatable results

Compatibility with the clamping system is defined by insert form, clearance angle, tolerance class, fastening method, size and thickness. The triangular geometry with an 11° clearance angle and a cylindrical hole plus single‑side countersink (40°–60°) requires a matching ISO‑type holder and the correct screw/washer combination to secure the seat and maintain repeatable cutting geometry. Correct seating reduces vibration and index‑to‑index variability, which in turn protects component tolerances and reduces scrap rates. Technical personnel benefit from verifying holder form and tolerance class before first use to ensure process stability.

Controlled chips and predictable wear for productive machining

The single‑side chipbreaker geometry is focused on finishing operations; it promotes controlled chip flow and consistent cutting forces when paired with the GT720 grade. This combination supports a steady contact zone that helps avoid abrupt edge deterioration and minimises process interruptions. In practice, predictable uniform wear leads to longer effective tool life and fewer mid‑shift adjustments. For process engineers, that translates into reduced setup times and a more economical production rhythm when machining medium‑strength steels.

Choosing and setting up the insert for best performance

Key dimensions to consider when selecting this insert are the inscribed diameter (13 mm), the plate thickness 3.18 mm and the corner radius 0.2 mm; these determine suitable feed and depth‑of‑cut windows for finishing passes. The triangular format provides three usable cutting edges per index, optimising cost per edge when rotated correctly. Clarification of terms: the clearance angle (often called relief angle) is the small angle between the flank and the workpiece that prevents rubbing; the corner radius influences both surface finish and edge strength.

FAQ

Is this insert compatible with standard ISO turning holders?
Compatibility depends on holder form, flank clearance and fastening; the TPGT130302 GT720 Tungaloy insert is ISO‑standard and requires a matching triangular seat, appropriate screw and washer for the cylindrical hole with countersink (SKU 6851886‑Tungaloy).

What applications is the GT720 grade intended for?
GT720 is specified for finishing to light machining of steel, emphasising surface finish, dimensional accuracy and uniform wear when used in the correct feed and speed window.

How does the 0.2 mm corner radius affect machining?
The 0.2 mm corner radius on the TPGT130302 insert balances surface quality and edge strength; it supports finer surface finish at lower feeds while maintaining sufficient robustness for light finishing cuts.

What clamping elements are required for secure fixation?
Use an ISO‑compatible triangular seat with the correct screw and washer combination sized to match the cylindrical hole and 40°–60° countersink; correct clamping preserves the insert geometry and repeatability.
