Seco 03095588 Turning Insert TNMG542-M5 TP3501 Carbide

Product Description

The SECO 03095588 is a TNMG542-M5 indexable turning insert manufactured from solid carbide with a CVD-applied Duratomic coating of TiCN and Al2O3. It carries a TP3501 grade designation and is engineered for medium to heavy-duty turning operations on steel and stainless steel workpieces. The triangular insert geometry provides 6 cutting edges, a 5/8-inch (0.6250 inch) inscribed circle, and a 1/32-inch (0.0315 inch) corner radius. The M5 chip breaker combines a chamfered and honed cutting edge style with a negative rake angle and neutral hand orientation, making it a versatile choice for production turning environments where consistent chip control is critical.

This insert is suited for general turning, back turning, boring, and facing operations on CNC lathes and turning centers. Primary target workpiece materials are carbon and alloy steels (ISO P20, P30, P40) and stainless steels. The neutral hand orientation allows use on both right- and left-hand toolholders. The TNMG form factor fits standard TNMG toolholders using clamp, pin, or lever-lock holding methods, making it a practical drop-in for shops already running TNMG tooling systems. The insert conforms to ANSI and ISO standards and carries the ISO designation TNMG270608-M5.

Key Features

• Neutral hand — compatible with right-hand and left-hand toolholders
• Supports clamp, pin, and lever-lock holding methods for broad toolholder compatibility
• Multi-use application: turning, back turning, boring, and facing

Compatibility

Designed for use in standard TNMG-style toolholders accepting clamp, pin, or lever-lock holding methods. Compatible with toolholders sized for a 5/8-inch inscribed circle TNMG insert. Conforms to ANSI and ISO TNMG standards; ISO designation TNMG270608-M5. Minimum order quantity is 10 pieces; package quantity is 1.

Installation Notes

Installation is performed by qualified machinists or CNC tool-setup technicians. Before indexing or replacing inserts, ensure the machine is stopped and locked out per shop lockout/tagout procedures. Seat the insert fully against the toolholder pocket and verify the clamping mechanism is properly engaged before resuming cuts. Inspect the insert pocket and seating surface for chips or damage that could affect insert positioning and cutting edge integrity.
