CPMT080308 UX30 indexable insert for milling (Tungaloy) — rhombic, 80° included angle

The CPMT080308 UX30 is an indexable milling insert designed for face, shoulder, slot, high‑feed and contour milling within compatible Tungaloy milling systems, requiring a matching insert seat and body geometry.

• Rhombic CPMT insert for milling
• Sharp cutting edge for low cutting forces
• Uncoated carbide grade UX30 for good chip control
• Central hole with cylindrical bore and single countersink

High‑performance cutting for reduced force and reliable chip control

The UX30 grade is an uncoated carbide formulated for a sharp cutting edge, prioritising low cutting forces and consistent chip formation. This combination reduces load on the toolholder and spindle, which improves cycle stability in delicate or thin‑walled components. The 0.8 mm corner radius balances edge strength and surface finish, while the 11° relief angle minimises rubbing on the flank face and helps maintain a clean shear plane. When low cutting force and controlled chip evacuation are decisive, this insert offers a pragmatic technical advantage.

Precise mounting and system compatibility for repeatable results

Designed for integration into Tungaloy milling systems, the insert features a centre hole with a cylindrical bore and single‑sided countersink (40°–60°) for secure clamping. Correct matching of the insert seat, plate geometry and milling body is essential for repeatable positioning and torque transmission; mismatched components can impair accuracy or cause premature wear. The rhombic geometry provides two usable cutting corners per index, facilitating cost‑effective indexing and predictable regrind intervals when applicable.

Application range and machining advantages in common milling tasks

Typical uses include face milling, shoulder milling, slotting, high‑feed operations and contouring, depending on the chosen tool family. In these roles the insert’s design delivers stable chip formation and low cutting resistance, which can translate into longer tool life and fewer interruptions for chip clearance. For materials and applications where minimal cutting force and clean chips are prioritized, the uncoated grade performs particularly well, offering a pragmatic solution for mixed‑batch production and setups where tool changeovers must be efficient.

Practical selection tips and handling recommendations

Select the insert when the process requirement is dominated by low force cutting or when chip control is critical. As the grade is uncoated, it is suited to applications where coating benefits—such as thermal barrier or anti‑adhesion—are less important than achieving a sharp edge and consistent shear. Ensure correct clamping torque and check that the 80° included angle and 3.18 mm plate thickness match the tool body specification before operation. Regular inspection of the cutting edge and adherence to the tool‑system matching rules will support repeatable performance and safe machining.

FAQ

What milling tasks is this insert suited to?
The CPMT080308 UX30 insert is suitable for face milling, shoulder milling, slotting, high‑feed and contour milling depending on the chosen milling body and tool family.

Which material characteristics make UX30 a good choice?
The UX30 uncoated carbide grade provides a sharp cutting edge and promotes good chip formation, making it appropriate where low cutting forces and clean chips are priorities.

How is the insert secured in the toolbody?
The insert is secured via a centre hole with a cylindrical bore and a single‑sided countersink (40°–60°); correct seat geometry and clamping are required for repeatable, secure mounting.

What effect does the 0.8 mm corner radius have on machining?
A 0.8 mm corner radius increases edge strength compared with very small radii and helps produce a consistent surface finish while still allowing acceptable cutting forces for finishing and semi‑finishing passes.

Is this insert compatible with standard Tungaloy systems and what is the SKU?
Yes, the insert is designed for Tungaloy milling systems when seat and geometry match; the item is listed as SKU 6802421‑Tungaloy (manufacturer SKU TUN6802421).
