Horn RU114004608TN35 Grooving Insert TN35 Carbide

Product Description

The HORN RU114004608TN35 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Built to Series U114 specifications, this right-hand insert delivers a cutting width of 0.046 inches and a maximum depth of cut of 0.157 inches. The TN35 grade carbide substrate is engineered for broad material compatibility, making it a reliable choice across a wide range of workpiece materials. Screw-style holding secures the insert firmly in the toolholder, maintaining repeatability insert-to-insert. Machining professionals and tool room technicians specify this insert when tight groove tolerances are required.

This insert is suited for external and internal grooving applications on turning equipment in production and job shop environments. The U114 series is a compact insert format commonly used for narrow groove profiles on small-diameter workpieces. The 0.008-inch corner radius helps control burr formation and surface finish at the groove edges. Its universal workpiece material rating covers cast iron, stainless steel, non-ferrous materials, steel, and high-temperature alloys, reducing the need to stock multiple grades across mixed-material production runs.

Installation Notes

Installation and replacement should be performed by a qualified machining professional or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate screw-drive tool to seat the insert fully against the pocket locating surfaces before torquing the clamping screw. Inspect the toolholder pocket for wear or debris before seating a new insert to maintain cutting geometry accuracy.
