EPGT 040104 GT9530 — Tungaloy turning insert (ISO rhombic 04, coated cermet)

A Tungaloy EPGT 040104 GT9530 indexable turning insert engineered for finishing and light universal turning of steel, offering improved surface finish and extended service life.

• Coated cermet grade GT9530
• ISO rhombic 04 geometry
• 0.4 mm corner radius
• Cylindrical hole + single-sided countersink

Enhanced productivity through wear-resistant coated cermet

The coated cermet composition of this grade, GT9530, is designed to combine wear resistance with a fine contact edge, making it particularly effective for applications where a high-quality surface finish matters. In practice, this means fewer parts rejected for surface defects and longer intervals between indexings, which supports a smoother production flow. The cermet coating also helps to reduce built-up edge when turning steels, translating into more consistent component dimensions and less rework.

Geometry and fit that simplify tooling decisions

The insert’s ISO rhombic 04 form and the specified 11° clearance (frewinkel) permit a wide range of standard ISO holders to be used, provided the holder matches the insert size, thickness and fastening arrangement. The 0.4 mm radius supports fine finishing operations while the 1.59 mm thickness and cylindrical hole with single-sided countersink (40°–60°) ensure reliable clamping and repeatable positioning. Explaining the geometry in this way helps to select the matching toolholder and to anticipate achievable feed and depth values for stable turning.

Recommended applications and machining strategy

Intended primarily for turning—both external and internal—the insert is best applied in stable setups and steady-state cuts where a fine finish or longer stand time is required. The single-sided chipbreaker promotes controlled chip formation in typical steel grades; selecting the appropriate cutting data for material, rigidity and machine power will maximise life. The grade is suited to finishing and light general-purpose turning rather than heavy interrupted cuts, so pairing the insert with a rigid holder and correct coolant strategy will further improve results.

Practical benefits: tool life, process reliability and support

Using a reliable indexable insert reduces unplanned stoppages and simplifies tool inventory management. The combination of GT9530 metallurgy and ISO standardisation yields predictable wear behaviour and repeatable part quality, supporting production planning and cost calculations.

FAQ

What materials is this insert best suited for?
The Tungaloy EPGT 040104 GT9530 insert is formulated as a coated cermet grade optimised for turning steel, delivering good surface finish and extended life in stable conditions.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm radius favours improved surface integrity and a refined edge profile, making the insert suitable for finishing passes and applications where dimensional accuracy is important.

Which holder features are required for correct fitment?
Correct fitment depends on matching the ISO form, insert size and 1.59 mm thickness; the cylindrical hole with single-sided countersink requires a compatible clamping arrangement and fastening screws sized for that hole type.

Is this grade suitable for heavy-duty interrupted cuts?
The GT9530 grade is intended for stable finishing to light universal turning; it is not primarily designed for heavy interrupted cuts—rigidity and choice of a more robust grade would be advised for such conditions.
