DNMG 150408 T9215 Tungaloy turning insert — CVD-coated carbide, 55° rhombic geometry

The DNMG150408 T9215 is a 55° rhombic indexable turning insert designed for external and internal turning in medium-steel applications, offering a balance of durability and productivity.

• CVD-coated carbide grade T9215
• 55° rhombic geometry for versatile turning
• 0.8 mm nose radius for precise profiles
• Double-sided chipbreaker design
• ISO-standard DNMG150408 with cylindrical hole

Maximised productivity with a CVD-coated carbide grade

The CVD-coated cemented carbide grade T9215 combines wear resistance with reliable fracture toughness, making it a first choice for medium-steel machining where continuous or lightly interrupted cuts are common. This coating system increases tool life under sustained cutting conditions and reduces the frequency of index changes, which in turn improves machine uptime and lowers unit cost per part. The specification emphasises consistent performance under industrial production loads, so process planners can expect steady results when the grade is matched to workpiece material and cutting strategy.

Geometry and dimensions that support precise turning

The rhombic 55° geometry and a 0.8 mm nose radius yield a versatile contact profile that suits a wide range of finishing and semi-finishing tasks. With a plate thickness of 4.76 mm and a standard 15 mm size, the insert fits common ISO DNMG toolholders; compatibility is governed by form, relief angle, tolerance class, clamping method, size and thickness. The 0° relief angle contributes to predictable cutting forces on stable setups. These geometric parameters allow engineers to calculate approach angles, feed per revolution and depth of cut with clarity, ensuring that process sheets and CAM data remain robust and reproducible.

Stable clamping and chip control for repeatable results

The insert’s cylindrical hole and rhombic form support stable clamping in matched holders, reducing vibration and improving surface finish. The double-sided chipbreaker design facilitates efficient chip formation and evacuation, which is especially helpful during longer cycles and when machining bars or forgings with variable interruption. Where machine stability is limited, selecting the appropriate chipbreaker and adjusting feed rates can markedly reduce edge stress and avoid premature wear, so maintenance intervals are extended and scrap rates decline.

Application guidance that reduces setup time and risk

As an ISO-standardised indexable insert for turning, the DNMG150408 T9215 is suitable for a broad set of workshop tasks including external profiling and internal shoulders, provided the toolholder geometry and clamping meet the manufacturer’s tolerances. Matching the chipbreaker and grade to the workpiece and cutting conditions is central to performance: the T9215 grade is optimised for medium steels and offers a reliable compromise between life and edge robustness. For tool-room planning, it is advisable to verify holder compatibility by comparing form, free angle and thickness with the insert designation and to favour rigid setups to exploit the grade’s strengths.
