Multisize Straight Shank Twist Drill Bits For Drilling Metal Iron and Aluminum Drill Bit

Q: Relationship between bit diameter and rotation speed: If the bit is drilled at a low velocity, the drilling efficiency will be low due to the low line speed, and the drill bit will be easily broken due to the small size and the small strength of the drill bit. But because the bit in drilling, large diameter, high speed, line speed will be very high, the bit will be very easy to damage on sticky steel drill.

Q: Relationship between pump pressure and bit pressure drop: Bit pressure drop and displacement are related to nozzle size. The greater the displacement, the greater the pressure drop; the smaller the nozzle, the greater the pressure drop.

Q: What drill is drilled on marble?: Do not use impact drilling, use an electric drill, and a high-speed steel drill, which is equivalent to grinding a hole in the marble!

Q: What's the difference between a UC drill and an ST bit?: The ST drill is easy to operate, easy to control diameter, more grinding times, and its range of use is relatively large. It can be used in general use, which is beneficial to general diameter drilling and double face plate and more than 6 layers of panels.

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.

Q: Impact drill and electric hammer drill is what is the difference: Impact drill and electric hammer drill bit is different: the impact drill used, need to tighten the special key. Is the electric hammer drill for electric hammer, electric hammer drill with locking clip assembly, simple, without any tools.

Q: What does the cutting depth of the drill mean 3D?: For example, 3D, the drill diameter is 20MM, then the effective drilling depth is 60MM, but the actual standard bit slot length must be about 80mm, because we should consider the chip space!!

Q: What steel blade drill bit, hardness above 60: 1, steel blade with steel drill bit.2, steel alloy steel is a kind of complicated, containing tungsten, molybdenum, chromium, vanadium carbide forming elements. The total amount of alloy elements is about 10 to 25%. It can maintain high hardness at high temperature (about 500 DEG C) in high speed machining, and HRC can be higher than 60. This is its main characteristic - red hardness, which can be used to make cutting tools. The Rockwell hardness of tungsten series and molybdenum high speed steel can reach over 63 after proper heat treatment. Because the steel is too hard, so can not bend, a love fold, it is difficult to punch.

Q: How does an electric drill drill a hole in the 16mm with a 10mm drill bit?.: 1. Use a ruler to measure the length of the 16MM around the wall. Mark the mark with a pen.2. Drill the drill with 10MM, drill a 10MM hole in the middle of the mark.3, with 10MM hole as the center, continue to open the drill, slowly rotating in a clockwise manner.4, rotating to the mark position, 16MM hole will be completed successfully.Remember, you can't go too far. You should take it slowly. You can turn it clockwise and counter clockwise for a while.
