Accupro SAT230400-14 Threading Tool 14 Tpi Internal Carbide

Product Description

The ACCUPRO SAT230400-14 is a single point internal threading tool machined from solid carbide and designed for precision thread cutting on CNC lathes and manual turning centers. It handles a minimum threading diameter of 0.23 inches with a cutting depth of 0.4 inches and runs at 14 threads per inch (TPI). The 29-degree profile angle makes this tool suited for standard thread forms requiring tight tolerances. With a bright/uncoated finish, the carbide substrate delivers hardness and wear resistance without an added coating layer. Machinists and toolroom operators use this insert-style threading bar where consistent thread geometry and tool rigidity are required.

This threading tool is intended for internal thread cutting applications in production machining and job-shop environments. The 5/16-inch shank diameter keeps the tool compact for boring into smaller bores, while the 2.5-inch overall length provides clearance for most standard toolholders. It is suited for threading ferrous and non-ferrous materials where a solid carbide construction offers the stiffness needed to maintain thread accuracy at depth. The 0.055-inch projection from edge determines insert exposure and affects chip clearance during the threading pass.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading operations
• 14 TPI cutting capacity with 0.23-inch minimum threading diameter
• 0.4-inch cutting depth supports threading into blind and through bores
• 29-degree profile angle for standard thread form geometry
• Bright/uncoated finish — no coating layer to affect critical thread dimensions
• 0.055-inch projection from edge and 0.028-inch flat width for controlled chip engagement

Compatibility

Designed as an OEM-style replacement and standard tooling selection for 5/16-inch shank internal threading setups on CNC lathes and manual turning centers requiring 14 TPI single point threading capability.

Installation Notes

Installation is performed by qualified machinists familiar with lathe toolholding systems. Secure the 5/16-inch shank in a compatible boring bar holder and verify tool centerline height before threading. Power down and lock out the spindle before seating or removing the tool. Do not exceed the rated cutting depth, and confirm bore diameter clearance before beginning the threading pass.
