Ultra-fine grain tungsten carbide taps for a wide range of thread standards.

Solid Carbide Tools for Production Threading
Solid carbide taps for repeatable internal-thread production in stable machining conditions — engineered around the thread specification, workpiece material, hole preparation, machine, and production target.
Choose the tap construction, geometry, and surface treatment around the thread, material, chip behavior, and machining setup.
A rigid cutting structure can support dimensional consistency and wear resistance when the machine, holder, and process are suitably stable.
Chamfer, flute form, rake, relief, and edge preparation are evaluated against the workpiece and hole condition.
Substrate and coating can be matched to the workpiece material, cutting conditions, and production objective.
Special diameters, pitches, lengths, and drawing-defined thread forms can be evaluated after the specification is confirmed.
Provide the thread designation and standard, class or tolerance, thread depth, through-hole or blind-hole condition, prepared-hole size, workpiece material and hardness, machine and holder, coolant method, and expected volume. These details determine whether a carbide tap is suitable and which geometry should be proposed.

Rigidity for repeatability. Solid carbide construction supports stable cutting where consistent thread geometry and production repeatability are required.
Geometry matched to chip flow. Flute direction, chamfer, edge preparation, and coating are reviewed against the material, hole type, and evacuation strategy.
Application review. JIAYI engineers evaluate the thread print, prepared hole, machine, holder, and process before recommending a standard or custom configuration.
Send the component drawing, thread specification, workpiece material, prepared-hole details, machine and holder information, coolant method, and production target. Our engineering team will review the application and prepare a custom-tool proposal after technical confirmation.
