Seco 00098802 Turning Insert Left Hand Triangle CP500

Product Description

The SECO 00098802 is a solid carbide turning insert engineered for precision metal cutting on CNC lathes and turning centers. Manufactured to ANSI and ISO standards, it carries a PVD-applied TiAlN and TiN dual coating that supports high-speed cutting while resisting heat buildup and flank wear. The insert features a 60-degree triangular shape with three cutting edges, a 5/32-inch (0.1600 decimal inch) inscribed circle, and a 1/64-inch (0.0157 decimal inch) corner radius. A positive rake angle and flat-top chipbreaker geometry promote clean chip evacuation. Licensed machinists and CNC operators install this insert in screw-clamped toolholders sized for the TDCH series.

This insert is designed primarily for machining stainless steel (ISO material code M) and performs across steel (P), cast iron (K), and super-alloys and titanium (S) workpiece materials. The CP500 grade designation places it in the M10, M20, and M30 material grade range, making it suited for light to medium turning passes where edge toughness and coating adhesion are both critical. It is a left-hand insert, so verify toolholder orientation before installation. Maximum depth of cut is 0.2520 inches.

Key Features

• PVD TiAlN and TiN dual coating for heat resistance and extended tool life
• 60-degree triangle shape with three usable cutting edges
• Positive rake and flat-top chipbreaker for efficient chip control
• 15-degree relief angle reduces rubbing on stainless and super-alloy cuts
• Screw-clamp holding method for secure, repeatable seating
• Meets ANSI and ISO standards; ISO code TDCH06T004L

Compatibility

Designed as an OEM-style replacement insert for TDCH-series screw-clamp turning toolholders accepting a 5/32-inch inscribed circle triangular insert with a left-hand orientation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque — do not overtighten, as this can fracture the carbide insert. Confirm left-hand orientation matches the toolholder before seating the insert, and inspect the pocket seat for chips or debris that could cause insert rocking.
