Carmex 16ER10STACMEP30 Threading Insert Solid Carbide

Product Description

The CARMEX 16ER10STACMEP30 is a laydown threading insert designed for external Stub Acme thread cutting at 10 threads per inch. Manufactured from solid carbide in an uncoated P30 grade, this right-hand insert delivers consistent thread geometry in a wide range of steel and ferrous materials. The 3/8-inch inscribed circle and 0.146-inch thickness conform to the 16 ER insert style, making it a direct fit for compatible toolholders. Machinists and CNC operators use this insert in turning and threading operations where Stub Acme profiles are required for power-transmission screws, jacks, and linear-motion components.

This insert is suited for production threading in job shops, tool rooms, and manufacturing facilities running CNC lathes or manual turning centers. Stub Acme thread forms are common in applications requiring a shallower thread depth than standard Acme, including lead screws, vises, and valve stems. The P30 carbide grade handles moderate cutting conditions in steel and cast iron at medium to higher feed rates. Minimum order quantity is 10 pieces; each package contains 1 insert.

Key Features

Compatibility

Designed for use in 16 ER-style laydown threading toolholders that accept a 3/8-inch inscribed circle insert. Verify toolholder specifications before installation to confirm insert style and seat geometry match.

Installation Notes

Installation is performed by qualified machinists following standard insert indexing procedures. Power down and lock out the machine before changing inserts. Use the correct torque wrench and manufacturer-specified clamping hardware for the toolholder to seat the insert properly. Inspect the insert pocket for chips or damage before seating a new insert.
