Accupro Acc -T150350 Threading Tool Internal Solid Carbide

Product Description

The ACCUPRO ACC -T150350 is a single point internal threading tool ground from solid carbide for use on CNC lathes and manual threading operations. It cuts internal threads with a minimum threading diameter of 0.15 inches and a cutting depth of 0.35 inches. The 60-degree profile angle covers Unified (UN) and metric-style thread forms across a range of 20 to 56 threads per inch (TPI). The bright, uncoated finish makes edge condition easy to inspect before and after use. At 0.0625 pounds, the tool is compact and suited for small-bore internal threading work where clearance is limited. Licensed machinists and CNC operators are the primary users.

This tool is intended for internal threading of small-diameter bores in production and job-shop environments. The 3/16-inch shank fits standard boring bar holders and small-tool holders common on CNC turning centers and manual lathes. The 2-inch overall length (OAL) keeps the overhang manageable in tight setups. Applications include threading hydraulic fittings, instrument components, and other small-bore parts where a 60-degree thread form is required and the minimum bore diameter is at or above 0.15 inches.

Key Features

• Solid carbide construction for rigidity and wear resistance in hardened and abrasive workpiece materials
• 60-degree profile angle compatible with UN and metric thread forms
• Thread range of 20 to 56 TPI in a single tool
• Minimum threading diameter of 0.15 inches for small-bore internal work
• Bright/uncoated finish allows direct visual inspection of cutting edge condition
• 0.035-inch projection from edge for clearance in confined bore entries

Compatibility

Designed for use in standard 3/16-inch shank tool holders on CNC turning centers and manual lathes where internal single point threading of small bores is required.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before inserting or removing the tool from the holder. Confirm shank seating and set screw torque according to the toolholder manufacturer specifications before running. Verify thread pitch and profile against part print before cutting; solid carbide tools are brittle and can fracture if subjected to interrupted cuts or excessive depth of cut beyond rated parameters.
