Feature 1The tapping tool handle has an accuracy of 0.01mm, with high concentricity, good processing effect, and improved machining efficiency. 2The tool holder contains a highaccuracy ball guide sleeve to reduce wear and prevent the tap from breaking and deforming. 3When processing the thread, the tapping tool holder can be extended and contracted to protect the tap when it is overloaded and stopped. 4Made of highspeed steel and quenched, it has good elasticity, wear resistance and stable performance. 5Floating and telescoping function, make slight synchronous expansion and contraction compensation during the tapping process, and increase the service life of the tap.
