SNMG 120408 GT9530 Wendeplatten - Tungaloy

Combining the wear-resistant GT9530 cermet grade with a 0.8 mm corner radius and a 0° relief angle yields finer surface finishes and longer tool life in stable turning operations; order the SNMG120408 GT9530 directly via Metav Werkzeuge or ask our consultants if needed.

SNMG 120408 GT9530 – Coated cermet indexable insert for turning (Tungaloy)

The SNMG120408 GT9530 is an ISO-format, square indexable insert designed for turning where surface finish and extended edge life are required.

• Coated cermet grade GT9530 for fine finishes
• 0.8 mm corner radius for reliable edge strength
• Square 12 mm size with 4.76 mm thickness
• Double-sided chipbreaker for flexible indexing

Higher-quality surfaces with longer edge life

The combination of a coated cermet substrate and the GT9530 grade delivers a noticeable improvement in finished surface quality while extending tool life under consistent cutting conditions. Cermet contains finely dispersed ceramic phases within a metal binder, which reduces built-up edge and gives a cleaner cut on steels. The result is fewer reworks and a steadier production rhythm when facing and light turning tasks, with predictable wear behaviour that supports planning and throughput.

Consistent performance and process reliability

Engineered for stable setups, the insert’s 0° relief angle and square geometry provide robust seating in compatible holders and even load distribution across the cutting edge. The double-sided chipbreaker enables two usable edges per index, supporting cost-effective part runs. In applications where rigidity and repeatability matter, the grade’s wear resistance and the insert’s dimensional tolerances help maintain part quality over longer tool cycles, improving overall process efficiency.

Mounting, compatibility and handling guidance

Compatibility with a toolholder is governed by form, relief angle, tolerance class, fixation, size and thickness. The ISO designation 120408 simplifies holder selection: a matching SNMG pocket, correct clamp or screw and the specified insert thickness (4.76 mm) guarantee correct fit. The cylindrical hole variant requires the appropriate clamp or screw set; ensure the retention parts and seating are free of debris to avoid premature edge chipping. Indexing is straightforward thanks to the square plate form, offering predictable repositioning for a fresh cutting edge.

Material suitability and application advice

This grade is optimised as a wear-resistant finishing to light general-purpose option for steel where a superior surface and longer life are desired under stable cutting conditions. The coated cermet chemistry favours fine feeds and moderate cutting speeds, producing low built-up edge and good surface integrity. For heavier roughing or unstable setups, a more robust geometry or different grade should be considered to preserve edge integrity and machine uptime.

FAQ

What materials is this insert suited for?
The SNMG120408 GT9530 insert is optimised for steel applications; the coated cermet composition favours finishing and light universal turning tasks.

How is the insert mounted in a holder?
The SNMG120408 format requires a matching SNMG pocket with the correct clamp or screw; the cylindrical hole design demands compatible retention hardware and correct seating to ensure stability.

What does the GT9530 grade offer compared with standard grades?
GT9530 is a wear-resistant cermet grade designed to deliver improved surface finish and extended edge life under stable cutting conditions compared with conventional carbide finishing grades.

How many cutting edges are available per insert?
Due to the square form and double-sided chipbreaker, the insert provides multiple indexing options; each side offers usable edges until the grade's wear limit is reached.

Is the SNMG120408 GT9530 suitable for roughing operations?
The insert is primarily a finishing to light universal grade; for heavy roughing or unstable setups, a more robust geometry or different grade is recommended to avoid premature wear.
