Seco 00064795 Threading Insert 60 Degree 3/8 Inch Ic CP500

Product Description

The SECO 00064795 is a solid carbide laydown threading insert engineered for right-hand internal threading operations. Running the 16NR insert style in the Snap Tap series, this insert is ground to a 60-degree partial profile and covers a thread range of 14 to 8 TPI, with a metric pitch equivalent of 1.75 to 3.00 mm. The carbide substrate is Micrograin grade, manufactured to ISO standards, and finished with a PVD-applied TiAlN/TiN multilayer coating under the CP500 grade designation. The A1 chipbreaker geometry supports consistent chip evacuation during internal threading cycles. At 0.12 pounds per piece, handling is straightforward for toolroom and production environments. Licensed machinists and CNC operators working in turning centers and lathes are the primary installers.

This insert is suited for internal threading on a broad range of workpiece materials. The CP500 grade carries a Universal primary workpiece classification, covering material codes K, M, P, and S, which correspond to cast iron, stainless steel, steel, and heat-resistant superalloys. This range makes the 00064795 a practical single-insert option for shops handling mixed-material production runs. It is positioned for use in both job-shop and production-floor turning applications where ISO-standard partial-profile threading inserts are specified.

Key Features

• Solid Carbide Micrograin substrate for extended edge life and dimensional stability
• CP500 grade with PVD TiAlN/TiN coating for wear resistance across universal material codes
• 60-degree included angle, partial profile, right-hand internal threading geometry
• Thread coverage: 14 to 8 TPI (1.75 to 3.00 mm pitch)
• A1 chipbreaker geometry for controlled chip formation in bore threading
• ISO-standard 16NR insert style for direct fitment in compatible Snap Tap toolholders

Compatibility

Designed for use in toolholders accepting the 16NR ISO insert style within the SECO Snap Tap series. Verify toolholder specification against the 16NR insert size code and 3/8 inch inscribed circle dimension before installation.

Installation Notes

Insert seating and clamping should be performed with the machine spindle fully stopped and all energy sources locked out per site LOTO procedures. Use the toolholder manufacturer's recommended torque procedure for insert clamping screws to avoid cracking the carbide substrate. Confirm thread direction, insert hand, and pitch selection against the part drawing before beginning the threading cycle. Worn or damaged inserts should be indexed or replaced before resuming production to prevent tool engagement failure in the bore.
