Seco 03280809 Turning Insert CCGT21.51F-AL TS2050 Carbide

Product Description

The SECO 03280809 is a solid carbide turning insert in the CCGT series, designed for precision metal cutting in CNC lathes and turning centers. It carries a multilayer TiAlSiN PVD coating under the manufacturer grade TS2050, which is engineered for performance on superalloys, titanium, stainless steel, and hard materials. The insert features an 80-degree diamond shape, a positive rake angle of 21 degrees, and a sharp cutting edge style. With a 7-degree relief angle and a corner radius of 0.0157 inches, it is suited for finishing and semi-finishing passes where tight tolerances and surface finish matter. This insert is installed and replaced by machinists and CNC tooling specialists in production and job-shop environments.

This insert is intended for boring, facing, and turning operations on superalloys, titanium, stainless steel, and hard workpiece materials. The AL chip breaker geometry supports controlled chip formation at the light-to-moderate depths of cut common in finishing work. The insert holds two cutting edges, making it a cost-effective option for high-value materials that demand consistent tool geometry across production runs. It is held in place by a screw-clamping method and fits toolholders compatible with the CCGT insert style and size code 21.51.

Key Features

• Solid carbide substrate with multilayer TiAlSiN PVD coating for extended tool life on difficult materials
• 80-degree diamond insert shape with positive 21-degree rake angle for reduced cutting forces
• Sharp cutting edge with AL chip breaker geometry optimized for finishing and semi-finishing passes
• 2 usable cutting edges per insert for improved value in high-alloy and hard-material applications
• Screw-clamp insert holding method for repeatable seating and quick indexing
• Conforms to ANSI and ISO standards; ISO code CCGT060204F-AL

Compatibility

Designed for use in CCGT-style screw-clamp toolholders compatible with size code 21.51 inserts. Suitable for multi-use applications including boring, facing, and turning. Primary workpiece material rating is superalloys and titanium (material code S); secondary ratings include stainless steel and hard materials (material codes M and H).

Installation Notes

Indexing and insert replacement should be performed by a qualified machinist with the machine fully stopped and locked out per facility lockout/tagout procedures. Ensure the insert pocket and seating surfaces are clean and free of debris before seating the insert. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer specification — do not overtighten. Verify insert seating and edge condition before resuming cuts.
