Seco 00049747 Threading Insert 10 Tpi Acme Solid Carbide

Product Description

The SECO 00049747 is a laydown threading insert engineered for external Acme thread cutting on CNC lathes and turning centers. Built from solid carbide with a PVD-applied TiAlN/TiN coating, it delivers consistent thread form and extended tool life across universal workpiece materials. The insert follows the 16ER style with a 9.53 mm inscribed circle, a thickness of 3.47 mm, and cuts at 10 threads per inch with a 29-degree included angle. The CP500 grade makes it suitable for a broad range of materials including steel, stainless, aluminum, and high-temperature alloys. Licensed machinists and tooling technicians specify this insert for production threading operations requiring precise Acme form geometry.

This insert is suited for right-hand external Acme threading applications on production turning equipment. The Acme thread standard is common in lead screws, power transmission components, jacks, and linear actuators where high load capacity and controlled clearance are required. The 16ER insert style seats in compatible laydown threading toolholders. The universal primary workpiece material designation covers cast iron, nonferrous metals, steel, stainless steel, and superalloys per ISO material codes K, M, N, P, and S.

Key Features

• Solid carbide substrate with PVD TiAlN/TiN coating for wear and heat resistance
• CP500 manufacturer grade rated for universal workpiece materials
• 10 TPI Acme thread profile with 29-degree included angle
• Right-hand external thread orientation for standard lead screw and power transmission applications
• 16ER insert style from the Snap Tap series for secure laydown seating
• ISO-standard insert geometry for consistent form accuracy

Compatibility

Designed for use in compatible 16ER laydown threading toolholders that accept the Snap Tap series insert style. Verify toolholder bore and seat geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified seating procedure — do not overtighten the clamping screw. Inspect the insert seat and clamp for chips or debris before seating the new insert to ensure proper form accuracy.
