DNMG150412 T9235 — Indexable turning insert, ISO rhombic, 55° — Tungaloy

DNMG150412 T9235 is a robust ISO-indexable turning insert designed for external and internal turning in steels, offering a tough CVD-coated carbide grade for interrupted cuts and unstable conditions.

• CVD-coated cemented carbide grade T9235
• Engineered for interrupted and unstable cuts
• ISO rhombic geometry with 55° cutting angle
• Double-sided insert with cylindrical hole

Consistent cutting in unstable conditions

The insert is made from CVD-coated cemented carbide, a combination that prioritises edge stability and predictable wear. The tough grade T9235 is formulated for steels at reduced cutting speeds and where cutting conditions are unstable or interrupted; this leads to fewer edge failures and more reliable cycle times. The design emphasises predictable tool life and reduced scrap rates, which supports smoother production flow and lower rework effort in mixed-batch or stop-start turning operations.

Secure seating and versatile holder compatibility

Thanks to the ISO rhombic geometry and standardised dimensions, the insert fits a wide range of external holders and boring bars. The cylindrical hole and accompanying fastening features ensure secure clamping and stable seat location, reducing the risk of micro-movements under load. Compatibility is determined by form, rake angle, tolerance class, fixing method, size and thickness, which simplifies holder selection and reduces setup time when integrating the insert into existing tool systems.

Practical geometry for balanced finishing and roughing

A 1.2 mm corner radius and a plate thickness of 4.76 mm offer a balanced compromise between strength and surface finish capability. The 55° cutting angle and rhombic profile enable versatile use for both light finishing passes and more aggressive material removal, depending on feed and depth-of-cut choices. The double-sided, reversible design maximises indexable life and reduces tool change frequency, improving uptime and lowering tooling costs per component.

Application-focused advantages and selection guidance

Designed primarily for turning of steel, the insert is best matched with a chipbreaker and grade that correspond to workpiece material, machining strategy and machine rigidity. Selecting the correct chipbreaker and matching the insert’s toughness to the machining stability will optimise process reliability. The ISO-standard format and clear dimensional data make it straightforward to compare alternatives and plan inventory for production or maintenance spare parts.

FAQ

What materials is this insert intended for?
The DNMG150412 T9235 insert from Tungaloy is intended primarily for machining steels and is optimised for interrupted and unstable cutting conditions.

How does the T9235 grade affect performance?
The T9235 CVD-coated grade provides a tougher carbide substrate, offering improved resistance to chipping in unstable cuts and extending usable edge life compared with harder, more brittle grades.

Can the insert be used for both external and internal turning?
Yes, the ISO rhombic geometry and 55° cutting angle allow the DNMG150412 T9235 to be used for both external turning and internal applications when paired with the appropriate holder or boring bar.

What are the key dimensional data to check when selecting a holder?
Verify the plate size (15 mm), thickness (4.76 mm), corner radius (1.2 mm) and the hole style (cylindrical) to ensure correct seating and clamping in the chosen holder.

Is the insert reversible and how many cutting edges are available?
The insert is double-sided and reversible, providing multiple usable cutting edges before replacement is required.
