What's the difference between left-handed tapping and conventional right-handed tapping?

The characteristics of the left tap are: the left tap is mainly used for golf clubs and some customized anchor bolts. Of course, in some cases, the back taps of bearings are processed to cooperate with the tool withdrawal operation of the lathe itself. The back taps are generally custom-made tapping, because the production is difficult and the price is relatively low, while the back taps are produced because of the requirements of high precision and fast processing speed. Because the demand for back taps is generally not great, they are all made into straight grooves, and the processing materials of the back taps are relatively wide, and the hardness ranges from 10HRC to 30HRC. Golf clubs with relatively small hardness, anchor bolts with relatively large hardness, and various wear-resistant shafts with relatively large hardness have a relatively large range. The biggest advantage of left-hand tap tapping is that it can discharge chips from the bottom of the well. Traditionally, chip removal is easy to cause tooth collapse or tooth decay due to chip accumulation. The tapping direction of the left-hand tap is opposite to that of the conventional right-hand tap, so that chips can be discharged from the tapping direction of the tap to avoid the interference of chips on the tapping teeth. Generally, high-speed steel containing cobalt or powder high-speed steel is used for tapping with left-hand tap, which is generally a blind hole, but it is also possible if it is a through hole.
