LNMU 0303ZE AH130 indexable insert for milling — DoFeed series, Tungaloy, double-sided chipbreaker

The LNMU0303ZE AH130 indexable insert is a 90° rectangular insert for high-feed milling, designed for pocketing and face milling in the DoFeed family.

• DoFeed high-feed design for efficient milling
• AH130 PVD-coated carbide for edge stability
• Double-sided chipbreaker, rectangular 03 form
• Centre hole with 40°–60° countersink for fastening

Maximise throughput with high-feed milling performance

The DoFeed concept is built to deliver large material removal rates with small axial depths; this results in significantly shorter cycle times when performing pocketing and face milling. The geometry provides a favourable cutting direction and stable engagement, which reduces vibration and enables higher feed per tooth. Designers and machinists benefit from the combination of a specialised cutting geometry and an insert form that is optimised for repetitive, high-volume material removal tasks, ensuring consistent productivity and improved machine utilisation.

Stable cutting edge and extended tool life through coating technology

The grade AH130, a PVD-coated carbide, is formulated to combine wear resistance with fracture toughness; this gives a sharp, stable cutting edge under the intermittent loads often encountered during milling. The PVD coating reduces built-up edge and improves thermal resistance, which helps maintain part quality over longer tool life. For production environments where process security and repeatable surface finish matter, this coating-and-substrate pairing reduces unscheduled tool changes and supports predictable machining cycles.

Secure clamping and economical indexing for continuous operation

The insert features a centre hole with a cylindrical bore and a double-sided countersink (40°–60°), allowing positive and repeatable clamping in compatible milling bodies. The rectangular 03 form and 3.18 mm thickness give rigid support in the pocket while the double-sided chipbreaker permits two usable cutting edges per orientation, lowering cost-per-edge and minimising inventory complexity. The 90° corner geometry and a 0° clearance angle contribute to a straightforward seat and reliable edge seating, which is especially useful in modular milling systems supplied as a complete assembly of milling body, matching indexable inserts and screws.

System compatibility and recommended applications

Supplied as part of the DoFeed model series, the insert is intended for high-feed milling families where time-volume efficiency is crucial. Typical uses include high-feed finishing and roughing passes in pocketing and planing operations, where a sharp cutting edge and process reliability are required. The insert forms part of a coordinated system—milling body, matching indexable inserts and fastening screws—so selecting matching components ensures correct seating, torque retention and repeatable performance across production batches.
