DCMT070202 GT9530 Tungaloy indexable turning insert — coated cermet, 7° relief

DCMT070202 GT9530 is an ISO‑standard rhombic indexable insert for turning, optimised for finishing and light universal cuts in steel.

• Coated cermet grade GT9530 for long tool life
• ISO rhombic insert, size 07, radius 0.2 mm
• 7° relief angle with cylindrical hole and countersink
• 2.38 mm thickness for stable clamping

High‑quality finishes from cermet technology

The coated cermet grade GT9530 delivers a reliable balance between wear resistance and surface finish, making it suitable for finishing and light universal turning in steel. Cermet combines ceramic hardness with metal‑binding toughness, so the insert maintains cutting edge integrity under steady conditions and produces improved surface quality compared with conventional grades. For operations where a fine surface and extended tool life are priorities, this insert reduces rework and supports consistent spindle cycle times.

Secure mounting and dimensional compatibility for production

Compatibility with toolholders is governed by form, relief angle, tolerance class, fixation, size and thickness; the rhombic ISO geometry and 2.38 mm thickness ensure secure seating in standard holders. The insert has a cylindrical hole with a one‑sided countersink (40°–60°) that supports repeatable clamping and minimal run‑out when paired with matched clamping sets and screws. This predictable mechanical interface lowers the risk of vibration and supports steady cutting conditions on medium‑stiff setups.

Application guidance for reliable machining results

With a 0.2 mm corner radius and single‑side chipbreaker, this insert suits light finishing and external turning where edge strength and surface integrity matter. The 7° relief angle provides effective clearance to avoid rubbing on the workpiece, while the chipbreaker geometry helps control chip flow on common steel grades. For best results, select cutting parameters and holder rigidity that match the intended surface finish and tool life goals; under stable cutting conditions the insert offers extended performance.

What the grade adds to process stability

The GT9530 grade focuses on wear resistance during finishing cuts, which translates into fewer indexings and more consistent part quality across runs. Reduced flank wear sustains dimensional accuracy over longer tool life, lowering tool change frequency and contributing to predictable production planning. In series production where surface quality and repeatability are essential, the insert supports higher first‑pass yields and stable downstream processes.

FAQ

What materials is this insert designed for?
The DCMT070202 GT9530 insert is intended primarily for use in steel machining, offering a finishing to light universal capability thanks to the coated cermet grade.

How does the GT9530 grade affect tool life and surface finish?
GT9530 provides enhanced wear resistance and edge stability, which helps to maintain a fine surface finish over extended cut lengths when used under stable cutting conditions.

Which holder features are required for correct compatibility?
Compatibility depends on holder form, relief angle, tolerance class, fixation method, size and thickness; holders designed for ISO rhombic DCMT inserts and matched clamping sets are required for reliable seating.

Is the insert suitable for heavy roughing operations?
This grade is optimised for finishing and light universal turning rather than heavy roughing; for high‑load roughing, a more robust geometry and different grade are recommended.

How does the hole and countersink affect clamping?
The cylindrical hole with a one‑sided countersink (40°–60°) enables repeatable clamping and reduced run‑out when used with appropriately dimensioned screws and underlays.
