DCMT070204 T9215 — ISO rhombic turning insert for medium steel by Tungaloy

The DCMT070204 T9215 is an ISO-standard rhombic indexable insert designed for external and internal turning of medium steel, offering a balance of wear resistance and toughness for continuous to slightly interrupted cuts.

• CVD-coated carbide grade T9215
• Optimised for medium steel machining
• Rhombic DCMT 07 shape, 55° cutting angle
• Single-sided chipbreaker, with hole and countersink

Boosted production through wear-resistant coating and grade

The CVD-coated carbide T9215 provides a measurable improvement in tool life and cycle stability, translating directly into higher productivity on medium steel components. The coating enhances wear resistance while the substrate maintains fracture resistance, which reduces unscheduled tool changes and scrap. For processes with continuous or lightly interrupted cuts, this combination supports stable chip formation and consistent dimensional results, making the insert a reliable choice where predictable tool life is a priority.

Consistent clamping and geometry for secure machining

Designed as an ISO-standard rhombic insert, the geometry and tolerances ensure compatibility with a wide range of holders when matching form, relief angle, tolerance class, fastening and thickness. The 55° entry angle and rhombic shape give a versatile cutting action suitable for profiling and general turning, while the 7° clearance minimises rubbing. The insert’s 0.4 mm corner radius balances edge strength and surface finish, and the 2.38 mm plate thickness adds rigidity for stable cuts. The central hole with cylindrical seat and single-sided countersink (40°–60°) secures positive location and repeatable clamping.

Practical guidance for application and process reliability

For turning operations, pair the insert with a holder and chipbreaker matched to component material and stability; the single-sided chipbreaker performs well for typical medium steel feeds and depths. The grade is formulated for continuous to slightly interrupted machining, so recommended cutting speeds tend to be higher than uncoated grades, with feeds adjusted to the chosen corner radius for the desired surface finish. When optimising parameters, focus on achieving consistent chip evacuation and avoiding excessive vibration—this preserves the coated edge and extends productive tool life. For process-critical production runs, a brief trial with representative workpieces will confirm the best speed and feed window.

FAQ

What materials is this insert best suited for?
The insert is optimised for medium steel; the CVD-coated T9215 grade delivers high wear resistance and fracture toughness for typical steel turning.

Can this insert be used for internal as well as external turning?
Yes, the rhombic geometry and 55° cutting angle make the indexable insert suitable for both external and internal turning when used with an appropriate holder.

How does the 0.4 mm corner radius affect results?
A 0.4 mm corner radius improves edge strength for roughing while still allowing a decent surface finish; smaller radii favour finer finishes at lower feeds.

Is the insert compatible with ISO-standard holders?
The insert follows ISO specifications; compatibility depends on matching form, relief angle, tolerance class, fastening, size and thickness to the holder.

What does the central hole and countersink provide?
The central cylindrical hole with a single-sided countersink ensures positive location and secure clamping, contributing to repeatable seating and reduced runout.
