SCMT120404 T505 — ISO turning indexable insert for turning, square 12 mm, Tungaloy

The SCMT120404 T505 is an ISO‑standard turning indexable insert engineered for efficient, economical machining of cast iron; its square form and 0.4 mm corner radius suit a wide range of external and internal turning operations.

• CVD-coated carbide grade T505
• Optimised for economical cast iron turning
• Square ISO insert SCMT 120404, 4.76 mm thick
• Single-sided chipbreaker, 0.4 mm corner radius

High economy and consistent edge life for cast‑iron turning

The insert’s CVD‑coated carbide composition (grade T505) is selected for a favourable balance between tool life and cost‑efficiency when machining cast iron. The coating enhances wear resistance at the cutting edge, which reduces flank wear under typical turning feeds and speeds; this results in fewer indexings per workpiece batch and lower overall machining costs. For production environments where predictable tool change intervals matter, the combination of coating and substrate material supports steady productivity and reproducible component finish.

Geometry designed to promote stable machining and chip control

A square plate with a 0.4 mm corner radius and a single‑sided chipbreaker helps maintain cutting stability during interrupted and continuous cuts. The 7° relief angle and 90° basic angle provide a neutral cutting geometry that is forgiving on varying depths of cut, while the chipformer reduces the risk of long, stringy chips that complicate handling. The insert thickness of 4.76 mm and its ISO form provide robust support in the seat, which contributes to reduced vibration and improved surface integrity on turned parts.

Compatibility, holder selection and practical workshop use

Compatibility with the toolholder is determined by the insert form, relief angle, tolerance class, fixing method, size and thickness. The plate is supplied with a cylindrical hole and a single‑side countersink (40°–60°) for reliable clamping in standard ISO external holders or boring bars. For best results, select a holder and clamping set that match the SCMT geometry and the chosen cutting parameters; this ensures the insert’s performance is translated into faster cycle times and stable machining. Spare mounting screws and proper seat condition complete the system set‑up for industrial use.

FAQ

What materials is this insert intended for?
The SCMT120404 T505 insert is formulated primarily for economical machining of cast iron; the T505 grade and its CVD‑coated carbide substrate provide good wear resistance and chip control when turning cast iron.

Which holder types are compatible with this ISO insert?
Compatibility depends on the ISO seat and clamping arrangement; the SCMT120404 is intended for standard ISO turning holders and boring bars that accept a square plate with a central hole and matching countersink.

How does the chipbreaker affect performance?
The single‑sided chipbreaker on this insert improves chip control and evacuation, helping to reduce entanglement and supporting consistent surface finish during both continuous and interrupted cuts.

What are the key geometric values to consider when setting cutting data?
Use the 0.4 mm corner radius, 7° relief angle and plate thickness 4.76 mm as reference values when selecting feed, depth of cut and spindle speed to balance surface quality and edge life.

Is the SCMT120404 available with other grades or coatings?
This listing describes the T505 grade with CVD coating; for other grades or coating combinations consult Metav Werkzeuge to discuss available alternatives and matching recommendations.
