SPGN090304-QBN — SPGN 090304 LX11 turning insert (Tungaloy)

The SPGN090304-QBN turning insert is an ISO-standard, square indexable plate designed for external and internal turning where balance between wear resistance and edge stability is required

• ISO-standard indexable insert
• LX11 Tungaloy carbide grade
• 0.4 mm corner radius for profile stability
• 11° clearance angle for reliable cutting

Consistent geometry for predictable machining results

The insert’s ISO conformity and square geometry provide a predictable seating and repeatability in ISO holders, which ensures reproducible cutting conditions across shifts. Compatibility with a clamping system depends on form, clearance angle, tolerance class, fixings, size and thickness; this means a correct holder choice reduces chatter and improves tool life. By standardising on ISO plates, process planners benefit from fewer tool changes and simplified inventory management.

Balanced grade for wear resistance and edge security

Built on a Tungaloy carbide grade LX11, the plate combines hardness for wear resistance with toughness to protect the cutting edge under variable loads. The QBN chipbreaker complements the grade by controlling chip form and evacuation, which reduces heat concentration at the cutting edge and supports longer, more stable tool life. This balance is especially useful for mixed-material production where occasional interrupted cuts or variability in clamping can occur.

Geometry and system integration that improve surface finish

The 0.4 mm corner radius and 11° clearance angle deliver a compromise between strength at the edge and the ability to produce a good surface finish on workpieces. The square 09 size and 3.18 mm plate thickness provide a robust contact area in the holder, aiding vibration damping for finishing passes. Selection of the right chipbreaker and grade for the workpiece material is decisive: pairing the plate with suitable holders and a correctly adjusted feed yields consistent dimensional accuracy and surface quality in both external and internal turning.

FAQ

What applications suit this indexable plate best? The SPGN090304-QBN insert is designed for general turning applications, suitable for both external and internal turning where a square 09 format and a 0.4 mm corner radius are appropriate.

Which materials can be machined with this grade? The LX11 Tungaloy carbide grade is optimised to balance wear resistance and toughness, making the plate suitable for a broad range of steels and mixed production environments; select the chipbreaker according to the workpiece material.

How is holder compatibility ensured for these ISO plates? Compatibility is ensured by matching the insert form and dimensions to the holder; key parameters are form, clearance angle, tolerance class, clamping method, size and thickness as noted for ISO-standard plates.

Is the chipbreaker suitable for finishing? The QBN chipbreaker provides controlled chip formation and evacuation; when combined with the right feeds and speeds it supports improved surface finish and dimensional stability.
