Carmex 16ER10STACMEBXC Threading Insert 10 Tpi Stub Acme

Product Description

The CARMEX 16ER10STACMEBXC is a solid carbide laydown threading insert designed for right-hand external Stub Acme thread cutting at 10 threads per inch. The insert features a TiN coating applied via PVD process, which increases surface hardness and extends tool life during repetitive threading operations. With a 3/8-inch inscribed circle and a thickness of 0.146 inches, this insert fits 16 ER-style toolholders commonly used in CNC lathes and turning centers. It is suited for machinists, toolroom operators, and production turning technicians who require accurate Stub Acme thread profiles on external workpieces.

This insert is used in threading applications where the Stub Acme thread form is specified, typically on power transmission components, lead screws, and jack screws. The 16 ER insert style is a standard laydown geometry compatible with a wide range of 16 ER-designated threading toolholders. The right-hand cutting orientation suits the most common lathe setups in both job shop and production environments. Minimum order quantity for this insert is 10 pieces.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiN coating via PVD process improves surface hardness and reduces built-up edge
• 10 TPI Stub Acme external thread profile for power transmission and lead screw applications
• Right-hand cutting orientation for standard lathe threading setups
• 3/8-inch inscribed circle fits 16 ER-style toolholders
• Manufacturer grade BXC for controlled cutting geometry and consistent thread form

Compatibility

Designed for use with 16 ER-style laydown threading toolholders configured for external threading operations. Suitable for right-hand Stub Acme thread profiles at 10 TPI.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and the spindle locked out per facility lockout/tagout procedures. Seat the insert fully and evenly in the toolholder pocket before torquing the clamp screw to the toolholder manufacturer's specified value. Verify thread pitch and profile with a thread gauge after the first pass before proceeding to full depth. Do not exceed the insert's rated cutting parameters as specified by the toolholder manufacturer.
