Scientific Cutting Tools TT120600A Threading Tool Internal

Product Description

The SCIENTIFIC CUTTING TOOLS TT120600A is a solid carbide single point threading tool designed for internal threading operations on CNC lathes and turning centers. It cuts threads ranging from 24 to 56 TPI with a minimum thread diameter of 0.12 inches and a maximum cutting depth of 0.6 inches. The tool features a 60-degree profile angle suited to unified and metric thread forms. An AlTiN+ coating provides thermal resistance and extended tool life in ferrous and hard materials. The 3/16-inch shank and 2-inch overall length make this a compact, rigid tool for small-bore internal threading work.

This tool is used in precision machining environments where small-diameter internal threads must be cut consistently. Typical applications include threading bores in hydraulic fittings, pneumatic components, instrumentation housings, and other small mechanical assemblies. It is suited for use in production shops, tool rooms, and job shops running steel, stainless, cast iron, and similar materials. Machinists and CNC operators working with tight bore diameters will find the 0.12-inch minimum thread diameter useful for fine-pitch internal work.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore threading
• AlTiN+ coating for elevated temperature performance and extended tool life
• 60-degree profile angle compatible with unified and similar thread forms
• 24 to 56 TPI range covers a wide span of coarse to fine internal thread pitches
• 0.6-inch cutting depth allows threading into deeper bores from a compact 2-inch OAL
• 3/16-inch shank diameter fits standard small-bore toolholders and boring bar setups

Compatibility

Designed as an OEM-style single point threading tool for use in standard 3/16-inch shank toolholders on CNC lathes and turning centers performing internal threading operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool turret is in a safe index position before mounting or removing the tool. Secure the shank firmly in the toolholder to the holding system manufacturer's specified clamping torque to prevent tool pull-out during the threading pass. Verify thread profile, TPI selection, and bore clearance against print specifications before running the first part.
