DCMT 070204 T9225 — ISO turning insert, rhombic 07 form, 7° clearance (Tungaloy)

The DCMT070204 T9225 is an ISO-standard rhombic indexable insert for external and internal turning, designed as a universal, robust grade for medium to heavy steel machining.

• CVD-coated carbide grade T9225
• Rhombic 07 form, 7° clearance angle
• Corner radius 0.4 mm, thickness 2.38 mm
• Cylindrical hole with one-sided countersink

Improved productivity through a universal, tough grade

The combination of CVD-coated carbide and the T9225 grade delivers a balance of toughness and wear resistance that supports steady removal rates under variable cutting conditions. This indexable insert is specified for medium to heavy steel machining, which means the cutting edge resists chipping during slightly interrupted cuts and maintains performance when feed or depth fluctuates. Selecting this grade reduces unplanned tool changes and contributes directly to higher throughput on series and batch turning operations, offering a measurable improvement in process reliability.

Geometry engineered for stable cutting and predictable finishes

The rhombic 07 form with a 55° included angle and 7° clearance provides a stable cutting attitude and accessible cutting edge for both external and internal turning. The corner radius of 0.4 mm smooths edge engagement, improving surface finish and reducing peak loads, while the 2.38 mm thickness ensures sufficient edge support for heavier cuts. These geometric parameters translate into controlled chip formation and consistent dimensional results, particularly when paired with an appropriate chipbreaker and cutting parameters matched to the workpiece.

System compatibility and secure clamping for safe operation

The insert conforms to ISO standards; compatibility with holders depends on form, clearance angle, tolerance class, fixing method, size and thickness. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to suit common clamping systems. A typical system comprises the ISO insert, a matching external holder or boring bar, a shim or clamp set and replacement screws. Following these criteria guarantees repeatable seating, secure clamping and straightforward indexability during tool changes, which simplifies tool management in the workshop.

Practical advantages for everyday turning operations

Designed as a robust universal option, this insert supports a wide material range when the combination of a sturdy cutting edge and good chip control is required. The one-sided chipbreaker helps to direct chips away from the workpiece and tool, reducing rework and protecting the machined surface. For shops seeking predictable tool life and easier process planning, this geometry and grade offer a pragmatic compromise between durability and surface quality, helping to maintain stable cycle times and reduce scrap rates.

FAQ

What materials is this insert best suited for?
The insert is formulated as a universal, robust grade and is primarily recommended for medium to heavy steel machining; the T9225 coating supports variable cutting conditions.

Does the DCMT070204 fit ISO holders?
Yes — the insert follows ISO geometry; correct seating requires a holder matching the insert form, clearance angle, tolerance and thickness.

Which chipbreaker should be chosen for interrupted cuts?
For interrupted or variable cuts, select a chipbreaker and cutting parameters that prioritise toughness; the one-sided chipbreaker on this insert aids chip control under such conditions.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius reduces peak cutting forces and typically improves surface finish compared with a sharper edge, while still permitting moderate feed rates.
