SCMT120408 T505 — Indexable milling insert for Fräsen (milling) by Tungaloy

SCMT120408 T505 is a square indexable insert designed for milling operations, optimised for economical machining of cast iron within Tungaloy milling systems

• CVD-coated cemented carbide grade T505
• Optimised for cast-iron milling
• Square 12 mm insert with 0.8 mm radius
• Cylindrical hole with 40°–60° countersink

Increased process reliability through controlled chip formation

The CVD-coated T505 grade delivers consistent wear behaviour and thermal resistance that supports stable cutting in interrupted and continuous milling. With an integrated one-sided chipbreaker, the insert promotes reliable chip control during planing, shoulder and slot operations, which reduces the risk of recut and minimises machine downtime. This translates into fewer tool changes and more predictable cycle times on production-critical components.

Secure clamping and geometry for repeatable accuracy

The SCMT120408 T505 insert features a square 12 mm format, a 4.76 mm plate thickness and a cylindrical hole with a single-side countersink (40°–60°) that ensures positive seating in compatible milling bodies. The 90° orientation and the 7° relief angle combine with the 0.8 mm corner radius to provide a secure interface and predictable contact stresses, helping to maintain dimensional consistency across repeated tool indexings and extending usable insert life.

Economical machining tailored to cast-iron applications

Designed specifically for the economic machining of cast iron, this insert balances cutting-edge wear resistance with cost-effective performance. The carbide substrate and CVD coating are selected to withstand typical cutting conditions for grey and compacted graphite iron, supporting efficient metal removal rates while preserving edge life. The result is an attractive cost per component for repetitive milling tasks where process stability matters.

Coating and grade explained for practical selection

A CVD coating applied to a cemented carbide substrate provides a hard, wear-resistant surface layer that excels at resisting abrasive wear and thermal shock during medium to high cutting speeds. The T505 grade is optimised for the conditions encountered in cast-iron milling, offering a compromise between toughness and hardness suitable for interrupted cuts. The system requirement — matching insert seat, geometry and cutter body — ensures the insert performs as intended when installed in the correct Tungaloy tool family.

FAQ

What materials is this insert intended for?
The insert is intended primarily for the economical machining of cast iron; the T505 grade and CVD coating are optimised for this application.

Which milling operations are suitable for this insert?
Typical uses include face milling, shoulder milling, slotting, high-feed and contour milling depending on the assigned milling body and tool family.

How does the hole and countersink affect clamping?
The cylindrical hole with a single-side countersink (40°–60°) provides a stable seating and improved axial location in compatible cutter bodies, enhancing repeatability during indexing.

What benefit does the one-sided chipbreaker provide?
The integrated chipbreaker improves chip control during interrupted cuts and helps reduce recutting, which contributes to more consistent surface quality and fewer unplanned tool changes.

Is the insert compatible with all Tungaloy milling systems?
Compatibility requires a matching seat and cutter geometry; the insert is intended for use in Tungaloy milling systems where the seat, geometry and cutter body are technically matched.
