Seco 00068403 Laydown Threading Insert CP500 Carbide

Product Description

The SECO 00068403 is a laydown threading insert designed for external partial profile 60-degree thread cutting on CNC lathes and turning centers. Manufactured from solid carbide micrograin substrate with a TiAlN/TiN PVD coating, this insert carries the CP500 manufacturer grade and belongs to the Snap Tap series. It covers a thread range of 7 to 5 TPI with a pitch equivalent of 3.50 to 5.00 mm, making it suitable for cutting coarse to medium unified and metric-compatible external threads. Right-hand cutting orientation and a 0.5000-inch inscribed circle are standard. Thickness measures 0.1854 inches. Licensed machinists and CNC lathe operators are the primary installers and users.

This insert is suited for external threading operations on a wide range of workpiece materials, including steel, stainless steel, cast iron, and high-temperature alloys. The universal primary workpiece material designation covers ISO material groups K, M, P, and S, giving it broad application across general machining, aerospace, and industrial component production. It is well matched to production turning environments where consistent thread form and tool life are priorities. The 22ER insert style is compatible with standard laydown threading toolholders that accept this geometry and inscribed circle size.

Key Features

• Solid carbide micrograin substrate for wear resistance and edge stability
• TiAlN/TiN PVD coating for extended tool life across universal workpiece materials
• Right-hand external partial profile 60-degree thread form, 7-5 TPI range
• CP500 grade with Snap Tap series design for reliable thread geometry
• ISO-standard geometry for compatibility with standard laydown threading toolholders
• Corner radius of 0.0160 inches for consistent thread root profile

Compatibility

Designed for use in 22ER-style laydown threading toolholders with a 0.5000-inch inscribed circle seat. Suitable for ISO-standard external threading applications across material groups K, M, P, and S.

Installation Notes

Insert seating and clamping should be performed with the machine fully powered down and the spindle locked. Use the correct torx or clamping screw driver specified by the toolholder manufacturer to avoid insert damage or improper seating. Verify insert orientation for right-hand cutting direction before resuming operation. Minimum order quantity for this insert is 2 units; package quantity is 1.
