Accupro SAT180500-16 Threading Tool 16 Tpi Internal Carbide

Product Description

The ACCUPRO SAT180500-16 is a single point internal threading tool manufactured from solid carbide. It is designed for cutting internal threads on lathes and CNC turning centers. The tool features a 29-degree profile angle and handles a minimum threading diameter of 0.18 inches with a maximum of 16 threads per inch (TPI). A 0.5 inch cut depth and 0.045 inch projection from the edge allow it to reach thread forms in bored holes and tight internal geometries. The bright, uncoated finish makes it well suited for non-ferrous materials and applications where coating buildup could affect thread accuracy. Machinists and CNC operators use this tool for precise, single-pass or multi-pass internal threading operations.

This tool fits standard 1/4 inch shank toolholders and is appropriate for single point threading operations in job shop, production, and maintenance machining environments. The 2.5 inch overall length provides enough reach for most common internal threading applications on manual and CNC lathes. It is used wherever a controlled, accurate internal thread form is required, including threaded bores in metal components across general manufacturing, repair, and custom fabrication work.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading
• 29-degree profile angle for precise thread form geometry
• Minimum threading diameter of 0.18 inches suits small-bore internal threads
• 16 TPI maximum thread pitch
• 0.5 inch cut depth for reaching thread forms inside bored workpieces
• Bright, uncoated finish — no coating buildup risk in non-ferrous or abrasive applications
• No coolant-through requirement; compatible with external coolant delivery

Compatibility

Designed as an OEM-style single point threading insert for use in 1/4 inch shank internal threading toolholders on manual and CNC lathes requiring a 29-degree profile at 16 TPI.

Installation Notes

Installation is performed by qualified machinists following standard lathe tooling setup procedures. Ensure the machine spindle is fully stopped and locked out before seating or adjusting the tool in its holder. Confirm shank diameter and projection measurement against the toolholder specification before use. Follow applicable shop safety standards and machine manufacturer guidelines for single point threading operations.
