Seco 03279993 Round Turning Insert 0.5in Ic Ticn Cvd

Product Description

The SECO 03279993 is a solid carbide round turning insert designed for precision metal cutting in CNC turning applications. Manufactured in the RCMM-46 series, this insert features a multilayer CVD coating — TiCN, Al2O3, and chrome — that provides wear resistance and thermal stability across a range of cutting conditions. The round insert shape (Insert Shape Code R) provides a full-radius cutting edge with an included angle of 360 degrees, making it well suited for facing, profiling, and general turning. The insert is neutral-handed and carries a honed cutting edge style with a positive rake angle of 14 degrees and a relief angle of 7 degrees. It fits standard RCMM-style toolholders using clamp, pin, or lever lock holding methods.

This insert is intended for machining steel as its primary workpiece material (ISO material code P), with secondary suitability for stainless steel (code M) and cast iron (code K). Applicable material grades include P20, P25, P30, and P35. The chip breaker designation is 46, and the ISO code for this insert is RCMM120400-46. It is rated for multi-use operations including facing, profiling, and turning, making it a versatile option for job shops and production environments running steel and stainless components. Licensed machinists and CNC operators working with lathes and turning centers are the primary installers.

Key Features

• Multilayer CVD coating: TiCN, Al2O3, and chrome for extended tool life on steel and stainless
• Full-radius round insert shape with 360-degree included angle — no preferential entry orientation
• Positive rake angle (14 degrees) reduces cutting forces on moderate-to-hard steels
• Honed cutting edge style improves edge stability and reduces microchipping
• 4 cutting edges per insert for cost-effective indexing
• Compatible with clamp, pin, and lever lock toolholder systems

Compatibility

Designed for use in RCMM-series toolholders. Industry standard number RCMM43-46 and ISO code RCMM120400-46 apply. Conforms to ANSI and ISO insert standards. Suitable for facing, profiling, and turning operations on steel, stainless steel, and cast iron workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench for the clamping screw — refer to the toolholder manufacturer specification for clamp torque values. Inspect the toolholder seat and clamping components for wear or debris before seating a new insert to ensure proper registration and avoid premature edge failure.
