Titan Usa TC84011 Thread Mill 1/4-20 3 Flute Solid Carbide

Product Description

The TITAN USA TC84011 is a solid carbide helical flute thread mill designed to cut 1/4-20 unified threads in both internal and external applications. With a 3-flute geometry and an AlTiN coating, it handles threading operations in a single helical pass, reducing cycle time on CNC machining centers. The shank diameter is 0.1875 inches, the cutting diameter is 0.1800 inches, and the length of cut is 0.5000 inches. Overall length is 2.5 inches. This tool is installed by machinists and CNC programmers working in job shops, production facilities, and tool rooms requiring precise thread milling on ferrous and non-ferrous materials.

This thread mill is suited for threading operations where tap breakage is a concern or where a single tool must produce multiple thread depths in one program call. The 1/4-20 thread profile at 20 teeth per inch (TPI) covers a common fastener thread size used across general manufacturing, aerospace, and industrial fabrication. It performs in both internal bore threading and external thread milling, making it a flexible option for shops running varied part families on machining centers with helical interpolation capability.

Key Features

• Helical flute geometry enables single-pass thread milling with helical interpolation on CNC machining centers
• Cuts both internal and external 1/4-20 threads with one tool, reducing tooling inventory
• AlTiN coating provides heat resistance and extended tool life in ferrous and hardened materials
• 3-flute design balances chip evacuation and cutting stability at typical thread milling feed rates
• Solid carbide construction delivers rigidity and dimensional accuracy over production runs
• No coolant-through requirement simplifies setup on standard machining centers

Compatibility

Designed for use on CNC machining centers capable of helical interpolation, producing 1/4-20 unified thread forms in internal and external configurations.

Installation Notes

Thread milling requires a CNC machining center with helical interpolation capability programmed to the correct thread pitch and diameter offset. Secure the 0.1875-inch shank in a collet or end mill holder appropriate for the shank size before beginning any operation. Verify spindle speed, feed rate, and helix angle in the CAM program before cutting — do not use tap-cycle G-codes for thread milling operations. Follow all machine guarding and workholding procedures per shop safety standards before initiating the program.
