CCMT 120412 T9215 turning insert — Tungaloy — CVD-coated carbide, 1.2 mm radius

CCMT120412 T9215 Tungaloy-Wendeplatte is an ISO-indexed turning insert designed for external and internal turning of steel, offering stable chip control and durable performance for continuous to lightly interrupted cuts

• CVD-coated T9215 grade for steel machining
• 1.2 mm corner radius for consistent profiles
• Single-sided chipbreaker for controlled chips
• ISO CCMT rhombic insert, 80° lead angle

Boosted productivity through predictable wear resistance

The CVD-coated carbide grade T9215 combines elevated wear resistance with good fracture toughness, which translates directly into longer tool life and fewer index changes during production. For shops machining mid-range steel, this means longer uninterrupted runs and reduced tooling logistics. The coated substrate helps maintain cutting-edge integrity under continuous and lightly interrupted cutting, improving process stability and reducing unexpected downtime.

Precise part geometry with a 1.2 mm corner radius

A 1.2 mm corner radius delivers consistent profile definition without excessive cutting forces, balancing surface finish and tool stress. The rhombic CCMT geometry with an 80° lead angle supports neutral cutting conditions, limiting radial forces and helping to produce accurate external and internal diameters. Where tighter tolerances are required, the insert geometry assists in maintaining repeatability across batches, reducing rework and scrap rates.

Reliable chip control and straightforward tool matching

The integrated single-sided chipbreaker is configured for effective chip formation during turning of steel grades, improving evacuation in through-turning and facing operations. Compatibility with standard ISO holders is determined by form, clearance angle (7°), tolerance class, fixation and thickness; the insert’s dimensions — 12 mm size and 4.76 mm thickness with a centred hole and cylindrical hole plus one-sided countersink (40°–60°) — facilitate straightforward tool assembly. This simplifies tool changeover and supports consistent machining outcomes.

Practical benefits for workshop efficiency

Using an ISO-indexed insert reduces inventory complexity: a single CCMT120412 style insert can be deployed across a variety of holders and toolposts when geometry and clamping match, lowering stocking requirements. The combination of a robust carbide substrate and protective coating means fewer tool rotations and predictable intervention intervals, helping to plan maintenance windows and optimise spindle time. The result is a measurable gain in operational throughput with reduced administrative overhead.

FAQ

Is this insert suitable for external and internal turning of steel?

Yes. The CCMT120412 T9215 insert from Tungaloy is designed for both external and internal turning and is optimised for mid-range steel machining with reliable chip control.

What benefits does the T9215 grade offer?

The T9215 CVD-coated carbide grade provides enhanced wear resistance together with good fracture toughness, supporting longer tool life and steady cutting performance in continuous to lightly interrupted operations.

Which holders are compatible with this insert?

Compatibility depends on holder form, clearance angle (7°), tolerance class, fixation, size and thickness; the insert’s ISO CCMT geometry and 12 mm size fit standard CCMT external holders and boring bars designed for CCMT inserts.

How does the chipbreaker affect machining?

The single-sided chipbreaker on this insert promotes controlled chip formation for common steel turning tasks, aiding chip evacuation and reducing the risk of chip entanglement in through-turning and facing.

What is the hole style and why does it matter?

The insert has a cylindrical hole with a one-sided countersink (40°–60°), which secures clamping stability and ensures correct seating on the insert seat, contributing to repeatable cutting performance.
