The first shot 10mm hole, and then pull out the 1/4 distance in the clockwise direction of reaming, turn around, and then pull out the 1/4 left until the drill wall, then try to put what if the expansion screw is not wide enough to continue with the previous method, until enough, almost feeling hammered into the turnbuckle screw do not pay attention to the problems.
Q:What kind of steel do you need to drill?!
A cemented carbide drill bit with an average size of 1 microns. This kind of drill not only has high hardness, but also improves the compressive and bending strength. In order to save the cost of many bits by welding handle structure, the original bit for the whole hard alloy drill, the back part of the handle adopts stainless steel, but the cost is greatly reduced due to the use of different materials and its dynamic concentricity is inferior to the whole hard alloy bit, especially in the aspect of small diameter.
Q:What drill does 42CrMo use to drill better?
Carbon structural steel 42CrMo, with ordinary high-speed steel drill bits can be larger, with 60 holes, first with a drill hole, then the reamer drill bottom hole expanding.

Q:Drills, drills, heating drills, will they be annealed?
Drilling, drilling, heating, if the temperature is too high, will lead to accelerated drilling wear, and even annealing.The cutting heat in the cutting process due to friction deformation and cutting material separation and rub the cut material between, so drilling after jobs have hot feeling, but not as long as the cutting drill out of the blue or purple, generally does not cause a bit of annealing.
Q:How can we change an ordinary drill bit into stainless steel?
With ordinary stainless steel drill bits to drill, speed down, such as 100, add a little vinegar when drilling well drilling. In two, the lowest drill about three hundred rpm, speed a little faster. It is better to drill on the vertical or rocker arm, and the speed can be adjusted lower.

Hard alloy, such as tungsten carbide and the like, or the surface of hard coating, such as titanium carbide can be, high strength stainless steel, hardness is not very high, a lot can be.
Q:What causes the drill bit to break at the end of the hole?
Small bit not used high speed, with small feed amount.A small drill can withstand torque is small, the use of high speed with a small amount of feed, can reduce the small rotating cutting output, so as not to drill to bear large torque.
Q:At present, the strongest oil drill bit, the deepest can drill how many meters?
Oil well drilling machine is mainly used for exploration and exploitation of underground oil and gas resources. It is composed of derricks, winches, rotary tables, big hooks, overhead cranes, taps, drill pipes, drills and so on. The drilling depth is 2-15000 meters.
