SNMG120408 GH330 SNMG Turning insert — double-sided chipbreaker, 0.8 mm radius (Tungaloy)

SNMG120408 GH330 indexable turning insert for external and internal turning with ISO‑standard form and secure clamping

• ISO‑standard square geometry
• GH330 wear‑resistant grade
• Double‑sided chipbreaker
• Cylindrical hole for secure clamping

Engineered for stable, repeatable turning results

The insert is manufactured from carbide and specified as grade GH330, combining wear resistance and edge stability for demanding turning operations. The ISO-conforming geometry ensures repeatable seat and clamping in compatible tool holders; this reduces set‑up variation and supports consistent component quality. The square plate form and 90° included angle deliver versatile orientation for both external and internal passes while the 0.8 mm corner radius enables reliable edge strength for semi‑finishing and finishing cuts.

Productivity and cost‑efficiency in everyday machining

A double‑sided chipbreaker design extends usable edges, lowering tool cost per cutting edge and reducing changeovers. The 4.76 mm plate thickness and robust construction contribute to vibration dampening and longer in‑process life, which in turn decreases downtime and scrap rates. Cylindrical hole mounting provides secure clamping, maintaining concentricity and minimising run‑out. These practical advantages translate into faster cycle times and more predictable machining results on the shop floor.

Choosing the right setup for optimal performance

Select the chipbreaker and grade according to workpiece material, machining stability and intended operation; the cutting geometry must match the holder by form, clearance angle, tolerance class, clamping method, size and thickness. The insert forms part of a system comprising the indexable insert, a matching external holder or boring bar, the proper clamp/seat and replacement screws. For unfamiliar materials or mixed production runs, appraising clamping rigidity and feed rates will safeguard the edge life and surface finish.

FAQ

What turning tasks is this insert designed for? This SNMG120408 GH330 indexable insert is intended for external and internal turning; selection of chipbreaker and grade depends on workpiece material and stability.

How does the chipbreaker design affect tool life? The double‑sided chipbreaker increases the number of usable edges and supports controlled chip formation, which helps extend service life under appropriate cutting conditions with the GH330 grade.

Which holder features are required for correct compatibility? Compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness; ensure the toolholder matches the ISO geometry of the insert.

Does the insert require a special clamping arrangement? The cylindrical hole and square plate form allow secure clamping in standard square pockets with the correct clamp/seat and fastening screws for repeatable clamping forces.

What performance benefits does the GH330 grade provide? The GH330 grade balances wear resistance and edge stability to offer reliable cutting behaviour, especially where consistent surface quality and economical edge life are priorities.
