Accupro SAT4902000-8 Single Point Threading Tool

Product Description

The ACCUPRO SAT4902000-8 is an internal single point threading tool ground from solid carbide and designed for cutting threads on CNC lathes and manual turning centers. It handles a minimum threading diameter of 0.49 inches with a cutting depth of 2 inches, making it suitable for threading deeper bores without tool interference. The 29-degree profile angle is matched to standard thread forms, and the bright uncoated finish preserves the as-ground carbide edge geometry. Shank diameter is 0.5 inches with an overall length of 3 inches. Machinists and tool-and-die technicians rely on this type of insert-style threading bar for precision internal thread generation in production and job-shop environments.

This tool is intended for internal threading operations on ferrous and non-ferrous workpieces where bore access and depth demand a rigid solid carbide bar. A minimum thread diameter of 0.49 inches and a 2-inch cut depth make it well suited for threading through-bores and blind bores on medium-sized turned components. At 8 threads per inch, it targets coarse-pitch thread forms common in structural and mechanical fastener applications. The 0.12-inch projection from edge keeps the cutting point positioned correctly relative to the shank centerline for accurate thread geometry.

Key Features

• Solid carbide construction for rigidity and vibration resistance in deep-bore threading
• 29-degree profile angle for standard thread form compatibility
• Minimum threading diameter of 0.49 inches with 2-inch cut depth capacity
• 8 TPI maximum thread pitch for coarse-pitch internal threads
• Bright uncoated finish preserves sharp as-ground cutting geometry
• 0.5-inch shank diameter and 3-inch overall length for standard tool holder fit

Compatibility

Designed for use in 0.5-inch bore tool holders on CNC and manual lathes configured for internal threading operations.

Installation Notes

Installation is performed by qualified machinists familiar with turning center tooling setup. Ensure the machine spindle is fully stopped and the turret is locked before loading or adjusting the tool holder. Confirm shank seating depth and tool height alignment to centerline before cutting. Verify thread pitch programming against the 8 TPI specification before initiating the threading cycle.
