Accupro Acc -T1801000 Internal Threading Tool Solid Carbide

Product Description

The ACCUPRO ACC -T1801000 is a solid carbide single point threading tool designed for internal thread cutting operations on CNC lathes and manual turning equipment. It handles a minimum thread diameter of 0.18 inches and covers a thread pitch range of 18 to 56 TPI, making it suitable for a wide variety of unified and metric-profile internal threads. The 60-degree profile angle conforms to standard thread forms. With a 1-inch cutting depth capacity and a bright, uncoated carbide substrate, this tool delivers consistent thread geometry in a compact form factor suited for small-bore internal work.

This tool is intended for use in machine shops, production turning cells, and maintenance facilities where precision internal threading is required. The 1/4-inch shank fits a broad range of boring bar holders and quick-change tooling systems common on manual and CNC lathes. It is well suited for threading operations on small-diameter bores in aluminum, brass, steel, and similar machinable materials. Machinists and toolroom technicians performing repair threading or new-part production will find the 18-to-56 TPI range covers most standard fastener thread pitches encountered in those applications.

Key Features

• Solid carbide construction provides rigidity and wear resistance for consistent thread form
• 18 to 56 TPI range covers a wide span of standard unified thread pitches
• 60-degree profile angle suits standard UN, UNC, UNF, and similar thread forms
• 0.18-inch minimum thread diameter enables small-bore internal threading
• 1-inch cutting depth allows threading deeper into blind or through bores
• Bright/uncoated finish — no coating buildup to alter insert geometry or clearance

Compatibility

Designed as a standard single point internal threading tool with a 1/4-inch shank, compatible with boring bar holders and quick-change toolpost systems that accept that shank diameter.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with lathe threading operations. Secure the shank firmly in the toolholder to the full recommended engagement depth before beginning any cut. Verify spindle speed and feed rate against the material being threaded before engaging the tool. Inspect the cutting edge for chipping or wear before each use, as solid carbide tools can fracture if subjected to interrupted cuts or excessive runout.
