CCMT120412 120412 T9225 turning insert (Tungaloy) — CVD-coated carbide, 1.2 mm radius

CCMT120412 is a standard ISO rhombic turning insert for external and internal turning applications, designed for medium to heavy-duty steel machining.

• CVD-coated carbide grade T9225
• Robust universal grade for steel machining
• Rhombic CCMT geometry, 80° cutting angle
• 1.2 mm corner radius, single-sided chipbreaker

Consistent cutting performance for demanding turning tasks

The combination of CVD-coated surface treatment and a carbide substrate in grade T9225 provides a balance of wear resistance and toughness intended for interrupted cuts and variable engagement. This construction reduces flank wear under higher thermal loads, which translates into more predictable tool life and fewer unplanned tool changes. For operations on medium to heavy steel, the insert’s durability supports longer unmanned runs and higher process reliability without sacrificing dimensional control.

Designed for system compatibility and straightforward integration

As an ISO-standard insert, the component fits into established tool systems when matched on form, clearance angle, tolerance class, fixation and size. The insert’s rhombic geometry and 80° cutting angle make it suitable for a wide range of turning holders and boring bars; correct pairing with the holder and shim/clamp set ensures clamping stability and repeatable results. The system approach—insert, external holder or boring bar, and replacement screws—simplifies spare-part planning and reduces tooling complexity on the shop floor.

Better chip control and surface quality with reduced rework

The single-sided chipbreaker is tailored for efficient chip evacuation during medium to heavy cuts, lowering the risk of built-up edge and improving surface finish on ferritic and alloyed steels. Stable chip formation helps to avoid downtime for chip clearing, while the robust grade supports consistent cutting forces, benefiting process repeatability. The net effect is improved productivity and a reduced total cost per part through fewer tool changes and less secondary finishing.

Practical mounting details that aid set-up and stability

Key design particulars assist setup and machining stability: a plate thickness of 4.76 mm, plate size 12, a 1.2 mm corner radius and a 7° clearance angle are matched to moderate-depth turning operations. The insert features a cylindrical hole with a one-sided countersink (40°–60°) which provides secure positive location in compatible clamping systems. These mechanical attributes make the insert straightforward to seat and align, aiding repeatable clamping and minimising run-out during operations.

FAQ

What materials is this insert suitable for?
The Tungaloy CCMT120412 in grade T9225 is designed primarily for medium to heavy steel machining; the grade and CVD-coated carbide substrate balance wear resistance and toughness for those materials.

How does the T9225 coating affect performance?
The CVD-coated layer on the T9225 grade improves thermal and abrasive wear resistance, which leads to longer tool life and more consistent surface quality when turning under higher cutting temperatures.

Is the CCMT120412 compatible with standard ISO holders?
Yes. The insert is an ISO-format rhombic plate and compatibility depends on matching form, clearance angle, tolerance class, fixation method, size and thickness with the chosen holder.

Which chipbreaker should be selected for light finishing cuts?
For finishing, a finer or negative chip control geometry is generally recommended; the CCMT120412 here features a single-sided chipbreaker suited to medium-to-heavy cuts—select a chipformer appropriate to the intended finish and feed rates.

What mounting details should be checked before first use?
Confirm plate seating on the shim, secure fastening with the correct screw and check the cylindrical hole with one-sided countersink aligns with the clamp. Also verify the holder matches the 12 size and 4.76 mm thickness to ensure stable clamping.
