1. The accuracy of the hole is high and no suitable twist drill bit can be found.
The high accuracy of hole is a hard problem. The only way to solve it is to customize the proper cutting edge. Of course, we need to find a fast twist drill bit manufacturer.
2. Is the drill bit easy to be blackened and worn?
The reason maybe the hardness of the product is too high or the speed of the equipment is too fast. We can select twist drill bit with higher hardness and higher wear resistance, or adjust the rotation speed of the equipment.
3. The drill bit is easy to break and not durable?
The general collapsing knife is either impurity, or the material and bit are unsuitable, or there is no counter rotation of the heart degree and lead to the collapse. It is recommended to use the center drill bit to guide the hole first and then drill holes. Secondly, the material of the twist drill bit should be replaced, and the cobalt containing high speed steel should be selected instead of the tungsten steel alloy drill bit.
4. Can’t find a suitable twist drill bit for drilling deep hole?
Deep hole-processing is really a difficult point to solve in the hole-processing. The best way is to choose the proper internal cooling drill bit to install the internal cooling equipment. The cooling degree of the outer cooling cannot be compared with the internal cooling twist drill bit. The deep hole drilling is the most effective way. Internal cold drilling is the most effective method for deep holes.
The above are the common problems encountered when drilling twist drill bits.
