SNGN 120412 LX21 indexable insert for turning — Tungaloy

SNGN 120412 LX21 is an ISO‑standard square indexable insert designed for general turning applications; compatible holders must match form, relief, tolerance class, fastening, size and thickness

• ISO 120412 form for standard holders
• Tungaloy LX21 carbide grade
• 1.2 mm corner radius for robust edges
• 0° relief with 90° insert angle

Increased tool life and predictable machining performance

The Tungaloy LX21 grade combines wear resistance, toughness and edge stability, creating a reliable cutting edge that keeps tool changes predictable and reduces unplanned downtime. The insert’s ISO‑standard geometry ensures compatibility with a wide range of external holders and boring bars; this standardisation simplifies inventory and tool management across mixed‑machine shops. Because the grade is matched to the insert geometry, the result is a measurable improvement in component consistency and repeatability over multiple shifts.

Consistent surface finish and flexible turning options

A 1.2 mm corner radius delivers a balance between cutting edge strength and surface quality: it reduces chatter on interrupted cuts and supports reliable stock removal without excessive workhardening. The square plate form with a 12 mm size and 4.76 mm thickness allows use in both facing and light roughing passes when paired with the correct holder geometry. For customers less familiar with insert selection, a larger radius increases edge stability, while a smaller radius favours finishing — the LX21 grade helps maintain performance across these conditions.

Efficient integration into existing tool systems

The insert’s 90° insert angle and 0° relief provide predictable cutting forces that are easy to account for in fixture design and cycle planning. The product fits into a system comprising an indexable insert, matching external holder or boring bar, clamp/seat and replacement screws; compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness. Since this insert is supplied without a chipbreaker and without a hole, it suits straightforward clamping systems and allows selection of chip control strategies according to material and operation, which supports flexible process optimisation on the shop floor.

FAQ

Which turning operations suit this insert best? This insert is designed for general external and internal turning operations; the SNGN 120412 LX21 performs well in facing, light roughing and finishing when paired with the appropriate holder and process parameters.

How does the LX21 grade affect cutting performance? The LX21 grade is formulated to balance wear resistance and toughness, giving stable edge life and consistent surface finishes under typical turning conditions.

Is a chipbreaker included with the insert? The insert is supplied without a chipbreaker; chip control should be selected according to the workpiece material and the chosen machining strategy.

What should be checked for holder compatibility? Compatibility depends on matching the insert’s form, relief angle, tolerance class, fastening type, size (12 mm) and thickness (4.76 mm) to the holder or boring bar specification.
