LNMU 0303UE AH3225 Milling insert by Tungaloy — PVD-coated carbide, double-sided chipbreaker

The LNMU 0303UE AH3225 is a rectangular, indexable milling insert engineered for precision face, shoulder and contour milling in compatible milling systems.

• PVD-coated carbide grade AH3225
• Double-sided chipbreaker design
• Cylindrical hole with 40°–60° countersink
• 90° rectangular insert, 3.18 mm thick

Robust performance through a wear-resistant grade

The PVD-coated carbide AH3225 delivers wear and chipping resistance tailored for milling operations that demand a consistently sharp edge alongside process security. The coating improves resistance to abrasive wear and extends the effective service life of the cutting edge, while the cemented carbide substrate ensures dimensional stability under load. This combination reduces unexpected tool changes and contributes directly to higher machine uptime and predictable component quality.

Designed for secure clamping and versatile milling tasks

Intended for use in matched Tungaloy milling systems, the insert requires a compatible seat, geometry and cutter body to function optimally; the system-based concept ensures repeatable performance. The insert supports typical applications such as face, shoulder, slot, high-feed and contour milling depending on the selected cutter family. The cylindrical hole with double-sided countersink (40°–60°) facilitates reliable clamping and accurate indexing, reducing runout and improving surface finish in serial and single-part production.

Geometry and handling advantages for stable chip control

The rectangular form with a 90° corner and 0° relief angle, combined with a double-sided chipbreaker, promotes controlled chip formation and evacuation across a broad range of cutting conditions. With a plate thickness of 3.18 mm and size 03, the insert is compact yet sturdy, enabling precise edge positioning and straightforward indexing when one side is worn. These mechanical features support consistent component tolerances and make the insert a practical choice where a sharp cutting edge and process reliability are required.

FAQ

What milling operations is this insert suited for?
The LNMU 0303UE AH3225 insert is suitable for face, shoulder, slot, high-feed and contour milling when used in the appropriate Tungaloy milling body and cutter family.

How does the AH3225 grade improve tool life?
The PVD-coated AH3225 grade increases resistance to abrasive wear and chipping, extending edge life and reducing the frequency of indexings or replacements in serial milling.

Is the insert reversible or indexable?
Yes, the rectangular LNMU 0303UE is double-sided and indexable; once one cutting edge is worn, the insert can be indexed to a fresh edge according to the cutter manufacturer's instructions.

What is the significance of the cylindrical hole and countersink?
The cylindrical hole with a 40°–60° double-sided countersink provides secure clamping and precise seating, which helps maintain repeatable positioning and minimise runout during milling.

Are there special requirements for mounting this insert?
The insert must be used in a Tungaloy-compatible milling body with matching seat and geometry; correct mounting torque and the specified clamp assembly ensure safe operation and repeatable results.
