The HORN RU114009400TN35 is a solid carbide grooving insert from the Series U114 product line, designed for external grooving operations on CNC lathes and turning centers. It features a 0.094 inch cutting width and a maximum depth of cut of 0.157 inches, making it well suited for narrow, precise groove profiles. A TiN (titanium nitride) coating improves surface hardness and wear resistance across a wide range of workpiece materials. The insert uses a positive rake geometry and is held in place by a screw clamping method, providing rigid, repeatable positioning for production machining applications. Installation and setup are performed by machinists and toolroom technicians.
This insert is intended for use in applications requiring consistent groove width and depth control on turning equipment. The U114 series insert geometry supports universal workpiece material compatibility, covering cast iron, steel, stainless steel, aluminum, non-ferrous alloys, and high-temperature alloys as indicated by material codes K, M, N, P, and S. It is a right-hand configuration insert. The screw-on holding method allows fast indexing during production runs. It is not a full-radius profile and is designated as a single-use, non-multi-use cutting tool.
Designed as a replacement-style grooving insert for HORN Series U114 toolholders and grooving systems accepting the U114 insert style with size code 009400.
Installation is performed by machinists using the appropriate Torx or hex key for the screw-clamping system. Always power down the machine and confirm the spindle is fully stopped before indexing or replacing inserts. Confirm the insert is fully seated in the pocket and the clamp screw is properly tightened before resuming cutting. Do not exceed the published maximum depth of cut for the insert grade and workpiece material combination.
