Accupro ACC-IDRT80 Threading Tool Bit Solid Carbide Rh

Product Description

The ACCUPRO ACC-IDRT80 is a single-point threading tool bit designed for internal thread cutting on metal lathes and CNC turning centers. Built to IDRT-80 industry standard, it features a micrograin solid carbide tip brazed to a steel shank, delivering the edge retention and surface finish quality that production machinists and toolroom techs require. The shank measures 0.5 inches wide by 0.5 inches tall, with an overall length of 3.5 inches. The 60-degree included angle suits standard unified and metric thread forms. Right-hand cutting direction makes it compatible with conventional lathe setups running toward the spindle.

This tool bit is suited for internal threading operations in metalworking environments including job shops, production floors, and toolroom applications. It is sized for tool holders and boring bars that accept a 0.5-inch shank. The 0.75-inch tip length and 0.575-inch minimum thread diameter make it appropriate for threading bores in steel, cast iron, aluminum, and similar machinable metals where carbide tooling is preferred over high-speed steel for extended run life and tighter tolerances.

Key Features

• 60-degree included angle compatible with standard unified and metric internal thread forms
• Right-hand cutting direction for conventional lathe and CNC turning setups
• 0.5-inch square shank fits standard IDRT-style tool holders and boring bar setups
• 3.5-inch overall length provides reach for typical internal threading depths
• Meets IDRT-80 industry standard for consistent fit and interchangeability

Compatibility

Designed as an OEM-style replacement and standard production tool bit for IDRT-style tool holders accepting a 0.5-inch square shank. No specific machine model compatibility data was provided in the product input.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Ensure the lathe or turning center is powered down and the spindle is fully stopped before mounting or removing tool bits. Secure the shank firmly in the tool holder to the holder manufacturer's specified clamping torque using appropriate set screws. Inspect the carbide tip for chipping or wear before each use, as a damaged carbide edge can compromise thread quality and workpiece finish.
