Seco 00059834 TNMG543-M5 TP40 Carbide Turning Insert

Product Description

The SECO 00059834 is a TNMG543-M5 triangular carbide turning insert manufactured to ANSI and ISO standards and graded TP40 for general-purpose metal cutting. The insert features a multilayer CVD coating sequence of TiC, TiCN, and TiN applied over a solid carbide substrate, delivering wear resistance and thermal stability in demanding turning operations. With a 5/8-inch (0.6250-inch) inscribed circle, a 3/64-inch (0.0472-inch) corner radius, and a neutral hand orientation, this insert suits a broad range of roughing and semi-finishing passes. The M5 chip breaker geometry uses a chamfered and honed cutting edge style to control chip formation across varying feed rates and depths of cut. Licensed machinists and CNC turning specialists are the primary installers of this tooling component.

This insert is intended for turning operations on steel and stainless steel workpieces, corresponding to ISO material codes P and M. Suitable material grades include P40, M35, and M40 applications. The insert supports back turning, boring, facing, and standard turning, making it a versatile choice for job shops and production turning environments handling a mix of carbon steel, alloy steel, and austenitic stainless steel components. It is compatible with tool holders designed for the TNMG insert series using clamp, pin, or lever lock holding methods.

Key Features

• Multilayer CVD coating (TiC, TiCN, TiN) for wear resistance and extended tool life on steel and stainless steel
• M5 chip breaker with chamfered and honed cutting edge for controlled chip formation
• 6 available cutting edges per insert, reducing per-edge tooling cost
• Neutral hand orientation supports use in standard right-hand or left-hand tool holders
• Maximum depth of cut up to 0.9685 inches for roughing capability
• Compatible with clamp, pin, and lever lock holding methods for broad tool holder flexibility

Compatibility

Designed for use in TNMG-series tool holders accepting clamp, pin, or lever lock insert retention. Suitable for ISO code TNMG270612-M5 equivalent applications. Primary workpiece materials are steel (ISO P) and stainless steel (ISO M) at material grades P40, M35, and M40.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before seating or replacing inserts. Verify that the tool holder pocket and clamping mechanism are clean and free of chips before installing the insert. Do not exceed the recommended depth of cut or feed rate range for the designated material grade, as improper parameters can cause premature edge failure or insert fracture.
