LN Series Slotting Mill Cutters
The LN slotting mill cutter series is a fantastic solution for narrow slotting applications. The LN slotting cutters come in both arbor and shell mill cutter options, accommodating groove widths ranging from .250 to .539 inches and cutter diameters spanning from 3 to 8 inches. One of its standout features is the radial adjustment in .020-inch increments, allowing for precise customization to meet specific machining requirements. With staggered internal keys and positive chip grooves, LN slot cutters ensure efficient chip evacuation and enhanced cutting performance. The ease of width adjustment through insert thickness further simplifies setup and operation, while enabling full side and face cutting capabilities. Additionally, these slot mill cutters can be used with neutral and positive chip-forming inserts. They feature four cutting edges for extended tool life and reduced downtime. Experience the unparalleled precision and efficiency of the LN slotting cutter series.
