Rectangle (L) milling inserts have four sides, with one pair of parallel sides being longer than the other pair. They have 90° nose angles and two cutting points for roughing, facing, turn milling, and chamfering tasks. These indexable inserts mount to a compatible toolholder, which attaches to a milling machine. They can be rotated (indexed) to expose a fresh cutting edge when the old one dulls. They can be replaced with new inserts of the same type or different types without removing the toolholder from the machine. Indexable milling tools require fewer tool changes than solid tools in high-volume metalworking and fabrication applications with high speeds, high feeds, and difficult-to-machine materials.
