Custom Wholesale Thread Forming Taps are designed for chipless internal threading in CNC lathes, machining centers, and automated production lines. Instead of cutting, they form threads by cold deformation, producing stronger threads with smoother surfaces and higher dimensional consistency.Made from premium HSS-E, PM steel, or solid carbide, these taps offer excellent hardness, torsional strength, and wear resistance. Optimized forming lobes reduce friction and forming torque, ensuring stable performance in long production runs. The chip-free process eliminates chip jamming and extends tool life. OEM/ODM customization is available for thread size, tolerance, geometry, and shank style, making them suitable
