Seco 00073166 Threading Insert Size 27 CP500 Solid Carbide

Product Description

The SECO 00073166 is a solid carbide threading insert designed for external thread-cutting operations on CNC lathes and turning centers. Manufactured in grade CP500 with a PVD coating process, this insert delivers controlled cutting performance on a range of workpiece materials. It carries a 27 insert size designation and is configured for right-hand cutting. The 60-degree included angle and 3 mm thread pitch make it suited for metric external threading applications. Machinists and CNC programmers working in production or job-shop environments will recognize the CP500 grade as a coated carbide platform intended for threading at stable cutting parameters.

This insert is used in external threading operations on turned components where a 3 mm pitch metric thread form is required. Typical applications include threading of shafts, fastener blanks, hydraulic fittings, and similar cylindrical workpieces. The right-hand orientation suits standard lathe spindle direction for the majority of turning setups. The 0.42 mm corner radius (0.0170 inches) influences thread root profile and should be matched to the thread standard being cut. This insert is appropriate for use in threading toolholders accepting size 27 inserts.

Key Features

• Solid carbide substrate provides rigidity and wear resistance in threading operations
• CP500 grade with PVD coating for controlled performance on a range of materials
• 3 mm external pitch for metric thread-cutting applications
• 60-degree included angle matches standard metric and unified external thread forms
• Right-hand cutting configuration for conventional lathe setups
• 0.42 mm (0.0170 inch) corner radius for thread root geometry control

Compatibility

Designed as an OEM-style replacement or direct-use threading insert for turning toolholders accepting a size 27 insert with external threading geometry.

Installation Notes

Threading inserts are installed and changed by machinists or CNC tooling technicians. Power down and lock out the machine before seating or removing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified procedure — do not overtighten the clamping screw. Verify insert orientation and pitch match the programmed thread cycle before running the first part.
