EPGT040102 GT9530 indexable insert for turning — Tungaloy, ISO rhombic 04, 11° clearance

The EPGT040102 is an ISO rhombic indexable insert intended for external and internal turning applications, engineered for stable finishing on steel where surface quality and extended tool life are required

• Coated cermet grade GT9530 for wear resistance
• Rhombic ISO shape 04 for versatile turning
• Clearance angle 11° for consistent cutting geometry
• Single-sided chipbreaker for stable finish

Improved productivity through a wear-resistant cermet grade

The coated cermet grade GT9530 delivers a balance between surface finish and tool life, making it particularly effective for finishing and light general-purpose turning of steel. The combination of coating and substrate reduces flank wear under stable clamping and cutting conditions, which in turn lowers tool-change frequency and supports uninterrupted production cycles. For production planners, this means fewer machine stops and more predictable tool consumption rates, helping to calculate cost-per-part with greater confidence.

Reliable geometry for precise surface quality

A rhombic ISO 04 profile with an 11° clearance angle and a 0.2 mm corner radius offers a predictable contact geometry that benefits dimensional control and surface appearance. The single-sided chipbreaker design assists in controlled chip formation during finishing cuts, reducing the risk of built-up edge and improving repeatability part to part. Operators unfamiliar with cermet grades will find that the moderate corner radius supports light radiused transitions without compromising edge strength.

Easy integration with standard toolholders and clamping systems

The insert conforms to ISO standards for form, mounting and tolerance, and is supplied with a cylindrical hole plus single-sided countersink (40°–60°) for secure fastening. Compatibility is determined by shape, relief angle, tolerance class, fastening method, size and thickness; as such, the insert fits a wide range of external holders and boring bars used in conventional turning centres. Choosing an ISO-compliant insert simplifies logistics, enables interchangeability and reduces the variety of spare parts carried in the tooling cabinet.

Practical selection guidance for stable turning conditions

Select the GT9530 variety when stable chip evacuation and a superior surface finish on steel are priorities; pair the insert with a holder that matches the insert form and tolerance class for optimal clamping stability. For coarse or interrupted cuts, consider an alternative grade designed for roughing; where finishing accuracy and longevity under steady feeds and depths are required, the coated cermet option provides clear advantages. If additional technical data or cutting parameters are needed, Metav Werkzeuge’s technical advisors can supply speed and feed recommendations based on the mounted assembly and workpiece material.

FAQ

What materials is this insert suitable for?
The EPGT040102 GT9530 Tungaloy indexable insert is optimised for turning steel, offering improved surface finish and longer life under stable cutting conditions.

How is the insert fastened to the holder?
The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) for standard clamping methods; ensure the holder matches the insert form and tolerance class for secure mounting.

Can this grade be used for roughing operations?
The GT9530 coated cermet is designed for finishing to light universal use; for heavy roughing or interrupted cuts, a tougher roughing grade is recommended instead of this finishing-oriented insert.

What benefits does the 0.2 mm corner radius provide?
A 0.2 mm corner radius balances edge strength and surface finish, making it suitable for precise finishing passes where small radii help to maintain dimensional tolerances without excessive edge wear.

Is the insert ISO-compliant for straightforward replacement?
Yes, the insert follows ISO dimensions and tolerances for rhombic turning inserts, which simplifies replacement and interchangeability with compatible toolholders.
