Accupro SAT1801000-16 Threading Tool 16 Tpi Internal Carbide

Product Description

The ACCUPRO SAT1801000-16 is a single point threading tool designed for internal thread cutting in precision machining applications. Built from solid carbide with a bright/uncoated finish, it delivers consistent performance in ferrous and non-ferrous materials. The tool features a 29-degree profile angle, cuts threads at 16 threads per inch (TPI), and reaches a minimum thread diameter of 0.18 inches with a 1-inch cutting depth. The 1/4-inch shank keeps it compatible with standard toolholding setups, and the 2.5-inch overall length suits bench lathes and CNC turning centers alike. Machinists and tool-and-die technicians are the primary users.

This tool is suited for internal threading operations in lathe and CNC turning applications where tight thread geometry and a compact shank profile are required. The 0.045-inch projection from edge and 0.024-inch flat width support controlled chip formation in confined bore diameters starting at 0.18 inches. It is appropriate for job shop, production, and maintenance machining environments where single point threading at 16 TPI is a recurring operation.

Key Features

• Solid carbide construction for hardness and wear resistance in threading operations
• 16 TPI thread form for standard unified and coarse-pitch internal thread cutting
• 0.18 inches minimum thread diameter allows work in small-bore applications
• 1 inch cutting depth supports full thread engagement in deeper bores
• 29-degree profile angle for accurate thread form geometry
• Bright/uncoated finish suitable for a wide range of workpiece materials
• No coolant-through design — compatible with flood coolant applied externally

Compatibility

Designed as an OEM-style single point threading insert tool for use in standard 1/4-inch shank internal threading toolholders on manual lathes and CNC turning centers.

Installation Notes

Installation and setup should be performed by a qualified machinist. Ensure the lathe or CNC turning center is fully powered down and the spindle is locked before mounting or adjusting the toolholder. Verify shank clamping torque per the toolholder manufacturer specifications and confirm tool centerline height before threading operations. Do not exceed the rated cutting depth of 1 inch per pass without validating against the machine and material setup.
