Tungsten Carbide Spiral Flute Tap Introduction

Tungsten carbide spiral groove is a tungsten carbide spiral flute tap capacity, according to the different spin divided into left and right hand. Left-handed tungsten carbide spiral chips tap tapping screw slots down row, suitable for through-hole; handed tungsten carbide spiral flute tap-tapping screw discharge when the chips upward, suitable for blind holes. 　　

Tungsten carbide spiral flute tap has some features: 1. it can be tapped to the lowermost blind hole; 2.cutting will not be left; 3.easy to enter into the bottom; 4. It has good machinability. Tungsten carbide spiral flute tap is the most commonly used, according to the different conditions with different helix angles.

Generally the larger the helix angle, the better the performance of the chip is. It’s suitable for blind hole machining, while through-hole machining is not the best choice.
