SDMT 1204AF T3130 square indexable insert for milling – Tungaloy

The SDMT1204AF T3130 is a square indexable insert designed for versatile milling tasks in Tungaloy milling systems, offering a balanced carbide grade for wear resistance and edge stability.

• Square 12 mm insert format
• Carbide grade T3130 for balanced performance
• Cylindrical hole with countersink 40°–60°
• Single-sided chipbreaker for stable chip flow

Durable carbide grade for consistent productivity

The insert is manufactured in carbide and specified with the T3130 grade, which combines wear resistance and toughness to maintain a stable cutting edge over longer cycles. This balance reduces the frequency of tool changes and helps maintain component surface quality in series production. The design supports a range of milling tasks — including face, shoulder, slot, high-feed and contour milling — so processes that demand repeatable results benefit from reduced downtime and predictable tool behaviour.

Geometry and mounting that secure repeatable clamping

With a 12 mm square format and a plate thickness of 4.76 mm, the insert features an included angle of 90° and a clearance angle of 15°, offering a robust contact area and positive seating in compatible tool bodies. The cylindrical hole with a one‑sided countersink (40°–60°) enables reliable centring and secure clamping, ensuring repeatable positioning and minimal micro-movement under load. Matching the seat geometry of the cutter body is essential for maximum life and consistent cutting performance.

Controlled chip formation for clean machining results

The single-sided chipbreaker is engineered to influence chip formation and evacuation, reducing the risk of built-up edge and improving surface finish in many common materials. When paired with an appropriate milling body and cutting data, the insert helps control vibration and chip flow, which contributes directly to process stability and predictable cycle times. The combination of geometry and chipbreaker function supports efficient material removal with fewer interruptions for rework.
