Seco 03064543 WNMA433 TK1501 Carbide Turning Insert

Product Description

The SECO 03064543 is a WNMA433 solid carbide turning insert in the TK1501 Duratomic grade, designed for high-productivity turning, boring, and facing operations on CNC and manual lathes. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and Cr, providing wear resistance and thermal stability across a wide range of cutting conditions. With a 0.6850-inch insert length, a 0.5000-inch inscribed circle, and a 0.0472-inch corner radius, this is an 80-degree trigon (W-shape) insert with a negative rake angle and a flat-top chip breaker geometry. It delivers six usable cutting edges per insert. Intended for installation by machinists and CNC tooling technicians in production and job-shop environments.

This insert is primarily rated for cast iron (ISO K10, K20, K30 material grades) and is also suitable for steel and stainless steel applications (ISO P and M workpiece material codes). Its chamfered and honed cutting edge style makes it appropriate for interrupted and continuous cuts in medium to heavy turning, facing, and boring operations. The WNMA-Flat Top series is compatible with clamp, pin, and lever-lock toolholding systems accepting WNMA-style inserts. ISO code for this insert is WNMA080412 and the industry standard designation is WNMA433.

Key Features

• Six cutting edges per insert maximize tool life and cost-per-edge value
• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for wear and heat resistance
• 80-degree trigon insert shape with negative rake and 0-degree relief angle (clearance code N)
• Chamfered and honed cutting edge reduces chipping on cast iron and steel
• Flat-top chip breaker geometry supports boring, facing, and turning applications
• Compatible with clamp, pin, and lever-lock toolholding methods

Compatibility

Designed for use in WNMA-style toolholders accepting clamp, pin, or lever-lock holding methods. Rated for ISO K (cast iron), P (steel), and M (stainless steel) workpiece materials. Conforms to ANSI and ISO standards for WNMA433 / WNMA080412 insert geometry.

Installation Notes

Installation is performed by a machinist or CNC tooling technician following standard insert-change procedures. Always disengage the spindle and confirm the machine is in a safe, de-energized state before seating or removing inserts. Use the appropriate torque wrench and insert screw driver for the specific clamping mechanism (clamp, pin, or lever lock) to avoid cracking the carbide substrate. Inspect the toolholder pocket for debris and wear before installing a new insert.
