high hardness, sharp and wear-resistant, smooth chip evacuation
High-speed steel material is used for overall heat treatment, high hardness, fast company speed, accurate thread, long service life
Terms and Conditions: When tapping, insert the head cone first to make the center line of the tap consistent with the center line of the drill hole . Rotate both hands evenly and apply a little pressure to make the tap enter the knife, no need to add pressure after the knife is entered

Generally used for thread processing of ordinary lathes, drilling machines and tapping machines, and the cutting speed is slow. 1.It has a good effect on machining materials with high hardness, materials that are easy to cause tool wear, cutting powdery materials, and through holes and blind holes with short tapping depths. 2.It has strong versatility, through-hole or non-through-hole, non-ferrous metal or ferrous metal can be processed, and the price is also cheap. But the target is also poor, everything can be done, and nothing is the best. The cutting cone part can have 2, 4, 6 teeth, the short cone is used for non-through holes, and the long cone is used for through holes.
