SNMN120412 T3130 – ISO turning insert for external and internal turning, Tungaloy

SNMN120412 T3130 is an ISO-standard, square indexable insert designed for general turning applications where a balanced combination of wear resistance and edge stability is required.

• ISO-standard turning insert
• T3130 grade for balanced wear and toughness
• 1.2 mm corner radius for stable cutting
• Square form, 12 mm size, 4.76 mm thick

Stable cutting with a resilient carbide construction

The insert is made from cemented carbide, engineered to deliver consistent performance in turning operations. The square insert form and the 1.2 mm corner radius provide mechanical rigidity at the cutting edge, reducing chatter and improving surface finish on interrupted and continuous cuts. Designed as an ISO-standard plate, it integrates into established toolholder systems when the holder matches in form, clearance and size. The primary benefit is a repeatable cutting geometry that supports reliable machining cycles and predictable tool life.

Balanced T3130 grade for mixed turning tasks

The T3130 designation identifies a Tungaloy cutting grade formulated to balance wear resistance and toughness, helping to preserve the cutting edge under varied cutting conditions. This combination supports longer intervals between indexings and reduces unexpected tool changes, which contributes to greater productivity. For less experienced users, the grade reduces the need for highly specialised cutting parameters while experienced operators will appreciate the grade’s tolerance to fluctuating feed and stability conditions.

Compatibility and mounting explained for secure integration

Compatibility with a chosen holder depends on the insert’s shape, clearance angle, tolerance class, attachment method, size and thickness. This insert features a 0° clearance angle and a plate thickness of 4.76 mm, with a standard 12 mm plate size and no hole; such details must be matched to a corresponding external holder or boring bar. Correct combination of insert geometry and holder ensures reliable clamping, thermal stability and accurate positional repeatability during external and internal turning operations.

Practical benefits in day-to-day turning

When used for external and internal turning, the insert supports process stability and cost-effectiveness: fewer interruptions for index changes, consistent surface quality and easier programming of cutting cycles. Where chip control is required, the selection of an appropriate chipbreaker and the T3130 grade together determine chip form and evacuation; choose the chipbreaker and grade to suit the workpiece material and machining stability. Overall, the component is a practical solution for workshops seeking a dependable, versatile indexable insert for a wide range of turning tasks.
