How to choose high quality tungsten steel left hole for automatic lathe hole machining

The left drill of tungsten steel is a very common bit for automatic lathe. It is mainly used for machining holes. Many people can’t distinguish between the left drill of tungsten steel and the left drill of the alloy. In fact, the two kinds of bits are all made of hard alloy, but there are only two kinds of methods in the market. Today, the small editor mainly wants to talk about the left drill of the tungsten steel and the machining of the automatic lathe. What kind of tungsten steel left drill is the most suitable to choose!

Many automatic lathe factories are not willing to choose tungsten steel left drill in the face of hole processing, because they think the left drill of tungsten steel is easier and more expensive, so more people will choose the white steel left drill, that is, the often said high speed steel bit or the cobalt left drill. The hole processing is indeed, the hardness of the commonly processed materials is not very high, and the most difficult to cut material is stainless steel.

But in the face of stainless steel is high speed steel left drilling is feasible, but the effect is really good enough? In fact, the effect is far higher than the high speed steel bit. The cost of the left drill of the tungsten steel in the market is about twenty percent higher than that of the high speed steel, but the cost of the left drill of the tungsten steel is much higher than that of the twenty percent, for example, in the processing of stainless steel 30. 4.316.201, and other difficult cutting materials, Xiaobian more strongly recommend tungsten steel left drilling.

There are a lot of tungsten steel left drills on the market, and the OBS tungsten steel left drill is recommended by the small editor. The left drill of OBS tungsten steel is divided into two kinds, one is the left drill with the fixed shank steel, the other is the straight handle tungsten steel left drill. The biggest difference between the two is the fixed handle and the straight handle, the other technology is almost the same, the advantages of the OBS tungsten steel left drill, the first is not easy to choose to choose quality easily. Hard alloy, in the process of processing will not be so easy to break, as long as the normal condition of the drilling shaft in the processing above the material said that the material will not appear broken. The second point is wear resistance!

The hardness of the left drill of the tungsten steel is far higher than the high speed steel left drill, so the left drill of the tungsten steel is better than the high speed steel left drill in the wear resistance. If it is not recognized, that is the quality problem of tungsten steel left drilling. As long as the quality passes, I believe no one will deny that the tungsten steel is left drilling. Quality is never proven by mouth but by action. If you choose to believe in Xiaobian, please contact the best tool and ask for more detailed information on OSB tungsten steel left drilling.
