Seco 03064485 Turning Insert CNMG433-MR7 TK1501 Carbide

Product Description

The SECO 03064485 is a CNMG433-MR7 indexable turning insert designed for single-point material removal on CNC lathes and turning centers. Built from solid carbide with a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — it delivers high wear resistance across a broad range of workpiece materials. The insert features an 80-degree diamond (rhombic) shape, a neutral hand orientation, a 0.0472-inch corner radius, and four usable cutting edges. The MR7 chip breaker geometry is optimized for roughing and medium machining operations, making it a practical choice where chip control and tool life are primary concerns.

This insert is suited for turning, facing, and boring operations in both roughing and medium-duty applications. Primary target materials include cast iron (K class), steel (P class), and stainless steel (M class), spanning high wear-resistance to moderate toughness demands. It mounts via clamp, pin, or lever-lock holding methods, covering most standard CNMG toolholders in production and job-shop environments. Installation is performed by licensed machinists and CNC operators in industrial machine shops. The insert carries ANSI and ISO certification and conforms to industry standard number CNMG433-MR7 and ISO code CNMG120412-MR7.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended wear resistance
• 80-degree diamond insert shape with T-Land cutting edge style for stable cuts
• MR7 chip breaker geometry rated for roughing and medium machining
• Four cutting edges per insert for improved cost-per-edge value
• Negative rake and negative side clearance for high-strength cutting edge retention
• Compatible with clamp, pin, and lever-lock toolholder systems
• Meets ANSI and ISO standards; dual-coded CNMG433 and CNMG120412

Compatibility

Designed for use in standard CNMG-style toolholders compatible with the CNMG433 (ANSI) and CNMG120412 (ISO) insert size codes. Suitable for boring, facing, and turning applications on steel, stainless steel, and cast iron workpieces. Verify toolholder clamping method (clamp, pin, or lever lock) before installation.

Installation Notes

Indexable inserts are installed and indexed by qualified machinists or CNC setup technicians. Power down and lock out the machine before changing or indexing inserts. Use the appropriate torque wrench for the clamping screw — refer to the toolholder manufacturer's specification for correct torque. Inspect the insert seat and pocket for chips or debris before seating a new edge to prevent insert rocking and premature failure.
