TNMU 1207R2 AH3225 Tungaloy indexable insert for milling — triangular 12 mm, PVD-coated carbide

TNMU1207R2 AH3225 Tungaloy indexable insert designed for versatile milling applications, offering wear- and chipping-resistant performance in face, shoulder, slot, high-feed and contour milling when matched to the correct cutter body and clamping system

• PVD-coated carbide AH3225 grade
• Triangular 12 mm insert, 60° cutting angle
• Double-sided chipbreaker for reliable chips
• Countersunk hole (40°–60°) for secure clamping

High-efficiency machining through wear-resistant coating and grade

The combination of a PVD-coated surface and a carbide substrate in grade AH3225 provides a notable improvement in abrasive and chipping resistance compared with uncoated grades. This composition enables longer intervals between indexings and tool changes, which translates into higher machine uptime and reduced handling costs. The proven coating also helps maintain a sharp cutting edge, resulting in consistent surface finish quality and predictable tool life in a wide range of milling operations.

Geometry engineered for process security and stable chip control

A triangular insert form and a defined 60° cutting geometry deliver a balance between strength and versatility; the shape supports higher feed rates while the core thickness preserves edge stability. The double-sided chipbreaker optimises chip formation for varying depths of cut, reducing vibration and supporting continuous metal removal. The insert’s with hole design and countersink (40°–60°) ensure reproducible clamping and correct seat alignment within compatible cutter bodies, enhancing overall process security.

Practical compatibility and system-level benefits

Designed as part of a complete milling system — cutter body, insert, clamp screw and shim where applicable — the insert requires that insert seat, geometry and cutter body are technically matched for safe operation. The medium-thickness profile (approx. 7.94 mm) and 12 mm size suit a broad range of holders intended for face, shoulder, groove, high-feed and contour milling. Clear specification of these parameters makes selection straightforward for process planners and purchasing departments seeking predictable performance across batches.

Material applications and recommended use cases

The indexable grade AH3225 is tailored for demanding milling tasks where a combination of a sharp edge and reliable wear behaviour is required. Typical applications include finishing and medium-duty roughing in steels and mixed alloy stocks when paired with appropriate cutting data. When combined with a compatible cutter family and correct clamping, the insert contributes to repeatable dimensional accuracy and consistent surface quality in production environments.

FAQ

What materials is this insert suitable for?
The TNMU1207R2 AH3225 insert is specified for a broad range of milling tasks and performs well on common steels and alloyed materials when appropriate cutting data is used.

How does the AH3225 grade improve tool life compared with standard carbide?
AH3225 combines a PVD coating with a robust carbide substrate to reduce abrasive wear and minimise chipping, providing longer intervals between indexings for the TNMU1207R2.

Is the insert compatible with any cutter body?
Compatibility requires that the insert seat, geometry and cutter body are technically matched; the TNMU1207R2 must be used in holders designed for its triangular form and 12 mm size.

What is the purpose of the countersunk hole on the insert?
The cylindrical hole with a double-sided countersink (40°–60°) ensures precise seating and secure clamping, which supports repeatable positioning and process stability for the TNMU1207R2.

Can this insert be used for high-feed milling?
When installed in a suitable holder and used with recommended feeds and speeds, the insert’s geometry and chip control make it applicable for high-feed and contour milling operations.
