DCMT 11T302 GH730 turning insert by Tungaloy — rhombic ISO insert with 7° relief

The DCMT11T302 GH730 turning insert is an ISO-standard rhombic insert designed for general turning applications, offering a balance of wear resistance and edge stability for a wide range of steels and alloys.

DCMT11T302 GH730 grade by Tungaloy Rhombic 55° geometry, 0.2 mm radius 7° relief angle for reliable clearance Cylindrical hole with 40°–60° countersink

Faster machining through optimised material grade and edge geometry

The GH730 grade combines enhanced wear resistance with fracture toughness to extend tool life under varied cutting conditions. Thanks to the carbide substrate and optimised microstructure, the insert maintains a stable cutting edge over longer tool cycles, which translates into fewer indexings and reduced tool-change downtime. The 0.2 mm corner radius supports modest finishing feeds while preserving tool strength, and the single-sided chipbreaker design promotes controlled chip formation, lowering the risk of re-cutting and improving surface consistency on turned components.

Secure clamping and ISO compatibility for predictable setups

Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness; the ISO designation DCMT11T302 ensures predictable interchangeability across standard external holders and boring bars. The insert’s rhombic shape with a 55° included angle offers flexibility for both external and internal turning, while the cylindrical hole with single-side countersink (40°–60°) provides positive seating and reliable repeatability in the seat. For workshop planning, include a suitable outer holder or boring bar, a shim or clamp set and replacement screws to complete the system.

Practical benefits and application advice for everyday turning

Selecting the GH730 sort complements the insert’s geometry by balancing wear resistance and edge stability, making it suitable for turning operations on a broad range of steels and alloyed materials. The moderate thickness of 3.97 mm contributes to mechanical stiffness in the clamp, reducing vibration in less rigid setups. When choosing cutting parameters, favour stable setups and moderate depths of cut to exploit the grade’s durability; a more conservative feed with the 0.2 mm radius will improve finish while preserving edge life. This combination is especially effective for mixed-batch production where process reliability matters.
