Horn RU114009408TN35 Grooving Insert Solid Carbide Tin

Product Description

The HORN RU114009408TN35 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured to U114 series specifications, this insert features a 0.094 inch cutting width and a maximum depth of cut of 0.157 inches. The Titanium Nitride (TiN) coating provides improved surface hardness and wear resistance across a broad range of workpiece materials. The insert is held in place by a screw-clamping method, providing repeatable seating and positive tool engagement. Machinists and tool-and-die professionals install this insert as part of a toolholder system configured for right-hand cutting direction.

The RU114009408TN35 is suited for grooving applications across universal workpiece material categories, including cast iron, stainless steel, non-ferrous metals, steel, and high-temperature alloys, corresponding to material codes K, M, N, P, and S. It is designed for use in production turning environments where consistent groove geometry and controlled chip formation are required. The positive rake geometry supports efficient cutting action and reduced cutting forces, making it appropriate for both light finishing passes and moderate-depth grooving on CNC turning equipment.

Key Features

• Solid carbide construction in manufacturer grade TN35 with Titanium Nitride coating for extended tool life
• 0.094 inch cutting width with 0.008 inch corner radius for controlled groove geometry
• Maximum depth of cut of 0.157 inches, within the 0.150 to 0.200 inch depth-of-cut range for this series
• Positive rake design reduces cutting forces and supports clean chip evacuation
• Screw-holding method ensures precise, repeatable insert indexing in compatible toolholders
• Right-hand cutting orientation; compatible with universal workpiece material grades K, M, N, P, and S

Compatibility

Designed for use in HORN U114 series toolholders configured for right-hand grooving inserts. Suitable for machining universal workpiece materials classified under codes K, M, N, P, and S. Material grade designation C5 and C6 applies.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle fully stopped before changing inserts. Use the appropriate torx or hex key driver specified by the toolholder manufacturer when seating the clamping screw. Inspect the insert pocket and seating surfaces for chips or contamination before installing a new insert, as debris in the pocket can cause improper seating and premature failure. Verify insert orientation for right-hand cutting before resuming operation.
