RNMU1307ZN T3225 indexable milling insert — high-feed milling, Tungaloy DoFeed

RNMU1307ZN T3225 is a round indexable insert designed for high-feed milling and pocketing applications within the DoFeed family, offering stable chip control and extended edge life for demanding material removal tasks.

• High-feed geometry for large chip volumes
• Tungaloy T3225 grade for edge stability
• Round insert, 13 mm diameter
• Double-sided chipbreaker, with hole

Faster material removal with stable cutting performance

The DoFeed-series geometry is engineered for high-feed milling, enabling large time-volume removal while keeping axial depths small. This design reduces cycle times in pocketing and face operations by distributing cutting loads across the insert geometry, which in turn improves process stability. The combination of the proven shape and the T3225 grade delivers a predictable balance between wear resistance and toughness, so operators can expect consistent cutting behaviour during extended runs.

Secure mounting and reliable chip control for efficient work

The insert features a cylindrical mounting hole with double countersink (40°–60°) and a double-sided chipbreaker, which together ensure accurate seating and improved chip evacuation under high-feed conditions. The round form and a diameter of 13 mm with a plate thickness of 7.94 mm support repeatable indexing and economical use of cutting edges. These mechanical choices reduce downtime for index changes and promote uniform surface quality on milled faces.

Practical advantages for workshop productivity

As an indexable insert manufactured in carbide, the component suits continuous production demands where tool life and replacement economy matter. The double-sided nature doubles usable edges per insert, lowering per-edge cost and simplifying inventory management. The grade's composition emphasises stable cutting edges and manageable flank wear rather than extreme hardness alone, which helps maintain surface finish and reduces the frequency of abrasive rework—benefits that feed directly into a more efficient machining process.
