DCMT070202 GT9530 – ISO rhombic turning insert by Tungaloy for finishing

DCMT070202 GT9530 is an ISO‑standard rhombic turning insert designed for finishing and light universal turning tasks in stable steel machining conditions

• Wear‑resistant GT9530 cermet coating
• ISO rhombic insert, size 07
• 0.2 mm corner radius for fine finishing
• Cylindrical hole with countersink 40°–60°

Consistent surface quality and extended tool life

The GT9530 grade is a coated cermet developed for finishing to light universal turning operations where surface quality and tool life are priorities. The composition of the cutting material delivers high wear resistance and stable cutting behaviour under steady clamping and machine conditions, which reduces process interruptions and repeat tool changes. For customers seeking reliable part finish without aggressive machining parameters, this insert supports lower cutting forces and improved part appearance compared with standard grades.

Precise fit and straightforward mounting for ISO holders

The insert follows ISO criteria for form, relief and tolerance so it integrates with compatible holders when matched by shape, relief angle, fastening and thickness. The rhombic geometry and 7° relief angle are optimised for common external and internal turning set‑ups, while the standard thickness of 2.38 mm ensures a secure clamping interface. The cylindrical hole with single‑sided countersink (40°–60°) supports reliable mechanical location and repeatable seating, reducing vibration and improving tool life in stable setups.

Application guidance and material suitability

Designed primarily for turning in steel, the insert is suited to finishing passes and light general‑purpose operations where a good surface finish is required. The one‑sided chipbreaker promotes controlled chip formation under stable conditions; selecting an appropriate chipbreaker and cutting parameters in line with workpiece stability is advised to exploit the grade’s full potential. For roughing operations or unstable setups, consider a tougher grade or increased support to avoid premature wear.

Small radius, fine results and process advantages

The 0.2 mm corner radius is tailored for fine finishing and minimal edge line disruption, enabling tight tolerances and superior surface appearance on turned components. The rhombic shape with an included angle of 55° offers versatility across a range of turning tasks while keeping cutting forces moderate. Combined with the coated cermet grade, this geometry helps to minimise rework and contributes to predictable tool change intervals, supporting efficient production runs and reduced downstream finishing effort.

FAQ

What materials is this insert suitable for?
The DCMT070202 GT9530 insert is intended primarily for steel turning applications, offering a balance of surface finish and wear life for finishing passes.

How does the GT9530 grade compare to standard carbide grades?
GT9530 is a coated cermet grade that typically gives improved surface quality and enhanced wear resistance under stable cutting conditions compared with conventional carbide grades used for finishing.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief, tolerance and fastening; the DCMT070202 follows ISO rhombic standards and is compatible with holders designed for size 07 rhombic inserts when matched correctly.

Is the 0.2 mm radius suitable for finishing tight tolerances?
Yes, the 0.2 mm corner radius is designed for fine finishing work and helps achieve good surface quality with controlled cutting forces.

What is the purpose of the cylindrical hole with countersink?
The cylindrical hole with a single‑sided countersink (40°–60°) provides secure mechanical location and repeatability during clamping, improving stability and reducing the risk of insert movement.
