Accupro Acc -T090400 Single Point Threading Tool

Product Description

The ACCUPRO ACC -T090400 is a single point internal threading tool ground from solid carbide for use in precision thread-milling and lathe threading operations. It handles internal threads with a minimum thread diameter of 0.09 inches and cuts across a range of 32 to 64 threads per inch (TPI). The cutting depth reaches 0.4 inches, and the 60-degree profile angle covers unified and metric thread forms. With a bright, uncoated finish, this tool suits machinists and toolroom technicians running ferrous and non-ferrous materials where coating is not required.

This tool is intended for internal threading applications in CNC lathes, manual lathes, and threading centers. The 1/8-inch shank diameter fits compact toolholders and live tooling setups used in precision machining of small-bore components. The 1-1/2-inch overall length (OAL) keeps the tool rigid in tight-clearance bores. It is suited for production and job-shop environments where fine-pitch internal threads are required in small-diameter workpieces.

Key Features

• Solid carbide construction provides rigidity and wear resistance for fine-pitch threading
• 60-degree profile angle covers unified inch thread forms
• 32 to 64 TPI range handles a broad selection of fine-pitch internal threads
• 0.09-inch minimum thread diameter enables threading in very small bores
• Bright/uncoated finish allows direct inspection of tool condition and suits non-ferrous applications
• 0.025-inch projection from edge supports controlled engagement in shallow or restricted bore entries

Compatibility

Designed as an OEM-style single point threading insert tool for use in 1/8-inch bore toolholders on CNC and manual lathes performing internal threading operations.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with single point threading setups. Ensure the machine spindle is fully stopped and all power is removed before mounting or removing the tool from the holder. Secure the 1/8-inch shank in a properly sized collet or toolholder to minimize runout. Verify thread profile alignment with a thread gauge before committing to a production run.
