SCMT 09T304 GT9530 Turning Insert — Tungaloy (coated cermet, 0.4 mm radius)

SCMT 09T304 GT9530 is an ISO-form indexable turning insert intended for finishing to light universal turning operations in steel, supplied in a square form for 90° turning applications.

• SCMT09T304 ISO indexable insert
• Coated cermet grade GT9530
• 0.4 mm nose radius for fine finish
• Compatible with square 90° holders

Precision finishing with a wear-resistant cermet grade

The insert is manufactured in a coated cermet grade GT9530, engineered for wear resistance and sustained surface quality during finishing and light universal turning of steel. Cermet combines ceramic hardness with metallic toughness, which reduces flank wear and helps maintain a consistent cutting edge under stable machining conditions. This results in improved surface finish and fewer insert changes, supporting efficient batch runs and predictable production cycles.

Accurate fit and straightforward ISO interchangeability

Designed to the ISO designation SCMT09T304, the insert offers reliable ISO interchangeability, simplifying holder selection and reducing setup variability. The square form with a 90° included angle and a 0.4 mm nose radius provides fine corner geometry suitable for tight tolerance profiles. The cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping and repeatable seating on compatible external holders or boring bars, reducing vibration and promoting repeatable part quality.

Practical machining benefits and process guidance

With a 3.97 mm plate thickness and a one-sided chipbreaker, the insert performs well in stable turning conditions where consistent chip control and surface integrity are priorities. The grade is optimised for finishing to light machining rather than heavy roughing; selecting feed and depth of cut to match the intended finish will yield the best balance between tool life and surface quality. Where higher stability or interrupted cuts are expected, consider holders with reinforced support to exploit the insert’s strengths.

FAQ

What materials is this insert designed for?
The SCMT09T304 GT9530 insert from Tungaloy is designed primarily for steel finishing and light universal turning operations where good surface finish and extended tool life are required.

How does the GT9530 coating benefit production runs?
The GT9530 coated cermet provides enhanced wear resistance and consistent edge integrity, which reduces the frequency of indexable insert changes and supports stable, predictable production results with fewer interruptions.

Is the insert compatible with standard ISO holders?
Yes. The ISO designation SCMT09T304 denotes compatibility with standard ISO square 90° holders, subject to matching form, clearance angle and tolerance class of the clamping system.

What chip control can be expected with this geometry?
The one-sided chipbreaker on the SCMT09T304 optimises chip formation for finishing operations; stable cutting conditions and appropriate feed settings will produce short, controllable chips and improved surface quality.

Can this insert be used for roughing operations?
The SCMT09T304 GT9530 is optimised for finishing to light universal turning. For heavy roughing or highly interrupted cuts, a tougher grade or alternative geometry is recommended to preserve tool life.
