Scientific Cutting Tools TT200800A Threading Tool Solid Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS TT200800A is a solid carbide single point threading tool designed for internal thread cutting operations. It handles a threading range of 16 to 40 TPI and starts at a minimum thread diameter of 0.2 inches, with a cutting depth of 0.8 inches. The tool features a 60-degree profile angle and an AlTiN Plus coating, which improves wear resistance and heat tolerance during high-speed threading passes. With a 1/4-inch shank and an overall length of 2.5 inches, it mounts in standard boring bar holders and threading tool holders used by machinists in production and job shop environments.

This tool is suited for internal threading on CNC lathes and manual lathes where tight-tolerance thread profiles are required. The solid carbide construction makes it appropriate for threading harder workpiece materials including alloy steels, stainless steels, and cast materials. The 0.045-inch projection from edge and compact shank geometry allow access to internal bores typical of hydraulic fittings, couplings, and threaded inserts. Machinists and CNC operators in precision machining, tool and die, and general metalworking shops are the primary installers of this tool.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding threading applications
• AlTiN Plus coating provides heat resistance and reduces friction during cutting
• Threading range of 16 to 40 TPI covers a wide variety of standard internal thread sizes
• 60-degree profile angle compatible with unified and metric thread form cutting
• Minimum thread diameter of 0.2 inches allows work in small-bore internal features
• 0.045-inch projection from edge supports precise thread engagement geometry

Compatibility

Designed as an OEM-style single point threading insert for use in standard 1/4-inch shank internal threading tool holders on CNC and manual lathes capable of synchronized threading operations.

Installation Notes

Installation is performed by machinists or CNC operators following standard tooling setup procedures. The tool should be seated securely in a compatible 1/4-inch shank holder and torqued to the holder manufacturer's specification. Confirm spindle speed, feed rate, and threading cycle parameters match the target TPI before cutting. Inspect the cutting edge for wear or chipping between operations, as solid carbide tooling is brittle and sensitive to interrupted cuts or excessive runout.
