Seco 74043731 Profiling Insert RCGS2F 883 Carbide

Product Description

The SECO 74043731 is a solid carbide, uncoated round profiling insert in the RCGS series, grade 883, designed for precision profiling and turning operations on CNC and manual lathes. The insert features a 1/4-inch inscribed circle (0.2500 inches), a thickness of 23/64 inches (0.3594 inches), and a maximum depth of cut of 0.1250 inches. With four cutting edges, a positive rake geometry, a 7-degree relief angle, and chipbreaker code 46, this insert is engineered to deliver consistent chip control and tool life across demanding cutting applications. It is held via clamp or pin and carries a neutral hand orientation.

This insert is suited for profiling and turning operations on non-ferrous metals, superalloys, titanium, and hard materials. Material grade compatibility spans N10, N20, N30, S10, S20, S30, H30, and H40, covering a broad range of workpiece material conditions. The T-Lock series mounting system and RCGS round geometry make it appropriate for contour-following and full-radius profiling passes in both roughing and finishing contexts. It is installed by machinists and CNC tooling technicians working in production turning environments.

Key Features

• Round RCGS geometry with 360-degree included angle for full-radius profiling passes
• Four usable cutting edges for extended tooling economy
• Positive rake angle with 7-degree relief for reduced cutting forces on difficult materials
• Chipbreaker code 46 for effective chip management across N, S, and H material groups
• Uncoated solid carbide construction — grade 883 — compatible with a wide range of material grades
• Clamp and pin holding compatibility for secure seating in T-Lock toolholders

Compatibility

Conforms to standards RCGS2F-46 and RCGS6.35-46. Compatible with toolholders designed for the T-Lock series RCGS insert style. Suitable for primary workpiece materials coded N, S, and H, with secondary compatibility across H, K, M, and N material codes.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before installing. Verify that the toolholder is rated for the RCGS insert style and that the clamping torque follows the toolholder manufacturer's specification.
