TPMT090204 GT9530 turning insert by Tungaloy — coated cermet, 11° clearance

TPMT090204 GT9530 is an ISO-format indexable turning insert designed for finishing to light universal turning, offering enhanced surface finish and extended life under stable machining conditions.

• Coated cermet GT9530 for fine finishing
• Triangular 09 form with 0.4 mm corner radius
• 11° clearance angle for stable cutting
• Cylindrical hole with one-sided countersink

Improved surface finish through wear-resistant grade

The GT9530 grade is a coated cermet engineered for finishing and light universal turning in steel, combining ceramic hardness with metallic toughness. This composition delivers a stable cutting edge that resists abrasive wear and reduces built-up edge in steady, well-supported setups. The coating further lowers friction and helps maintain a consistent contact zone, which translates into improved surface finish and longer intervals between indexings. For operations prioritising component quality, the material and coating choices in this grade provide a measurable improvement in finished-part consistency.

Secure geometry and repeatable seating for precision work

A triangular insert form with a 0.4 mm corner radius and an 11° clearance angle delivers a balance between edge strength and accessibility to detail. The insert’s cylindrical hole with one-sided countersink ensures reliable clamping in compatible ISO holders; the countersink angle (40°–60°) helps centre the insert and prevents lateral movement under cutting loads. These geometric details promote repeatable positioning, which is essential for batch production and setups where tolerance adherence is critical. Compatibility with a holder is governed by form, clearance, tolerance class, mounting method, size and thickness.

Optimised for turning steel in finishing and light general machining

This indexable grade performs best in turning operations where a high-quality surface and predictable edge life are required. The combination of a fine corner radius and a coated cermet substrate makes the insert suitable for finishing passes and light general-purpose cuts in various steels. Selection of the appropriate chipbreaker and cutting parameters should match workpiece rigidity and machine stability to exploit the grade’s strengths. Under stable conditions and with correct speeds and feeds, the grade reduces vibration sensitivity and promotes consistent results across a production run.

Easy integration into ISO insert systems and workshop routines

The insert is part of the ISO indexable turning insert system and integrates with standard external holders or boring bars, plus the usual shims/clamp sets and replacement screws. Key assembly items in a typical system are the ISO-format insert, a matching external holder or boring bar, the supporting shim/clamp set and the fastening screw. Because the insert is ISO-standardised, it offers cross-compatibility across a wide range of toolholders—provided the holder matches the insert form, mounting style and tolerance class. That standardisation simplifies stocking and reduces changeover complexity in mixed-machine workshops.

FAQ

Which materials is this grade best suited for?
The TPMT090204 GT9530 insert is optimised for steel machining, offering excellent surface finish in finishing and light general-purpose turning operations.

Can this insert be used for stainless steel and other alloys?
The GT9530 grade can be applied to stainless steel and similar alloys in stable setups, but cutting data and chipbreaker choice should be adapted to the material to avoid built-up edge and to maintain tool life.

How does the hole and countersink affect clamping?
The cylindrical hole with one-sided countersink (40°–60°) centres the insert and improves seating stability, reducing lateral movement under load and ensuring repeatable positioning in compatible holders.

What does the 0.4 mm corner radius mean for component finish?
A 0.4 mm radius provides a fine but robust edge that helps achieve a smooth surface while retaining sufficient strength for light finishing cuts.

Which system components are required to mount this insert?
A standard ISO setup requires the insert, a matching external holder or boring bar, a shim/clamp set and the correct fastening screw; compatibility depends on the holder’s form, tolerance class and mounting type.
