Q: The difference between steel teeth and inserted cone bit: The inserted three bit bit is a new kind of wear-resistant material with high strength and high toughness alloy tooth and steel tooth bit surface. It can increase the drilling speed of the bit while maintaining the high mechanical drilling speed of the steel tooth bit. Different specifications of cone bit, three cone bit, Jianghan rock bit, drilling wells with cone drill, oil cone bit, mine rock bit, geological rock bit, gas wells cone bit, PDC bit, diamond bit, imported composite drill, 5 wing PDC drill bit, 4 wing PDC drill bit, 8 blade PDC bit.

Q: How do I turn on the electric bit?: There are two kinds of commonly used, a card, a clip, clip to press the drill chuck can pull out the drill, clip with keys to open, can also be used when a round steel chisel, hammer knock loose counterclockwise on the line.

Q: How to remove the electric clock bit: The outer part of the drill joint is provided with a plastic sleeve, and one hand pushes the plastic sleeve inward, and the other hand holds the drill bit to pull out the drill bit.

Q: What drill is used for machining holes with a diameter of 3mm?: In general, if the drill pointed to the comparison of the grinding, it is recommended to be smaller than the final hole 0.10mm, of course, this is the processing of steel parts, plastic and other processing holes will shrink back, generally take a little larger diameter. If the final size of the strict requirements, it is best to drill rough, such as 2.5 of the drill bit, and then 2.8-2.9 drill reaming, and finally reaming, precision reaming, usually with 3.0mmD5-D6 class. Drill what specifications have, in general, the first series of multi-point, second, third series less, large dosage, you can find manufacturers custom. Can not find the words, you can buy a larger diameter of their own in centerless grinding or grinding on the outer circle to change, but the effect will be worse, the drill has inverted cone, not necessarily grinding, and need experience.

Q: How can we change an ordinary drill bit into stainless steel?: Ordinary drill can also drill stainless steel, but the performance is a little bit worse, the use of cutting speed is slower, plus special cutting fluid or vegetable oil for cooling lubrication.

Q: What's the difference between a flashlight and an impact drill?: The drill bits used are not the same.General electric drill is small power, drill iron sheet, drill wood whatPercussive drilling is usually made of concrete, or wall holes, the power is relatively large.

Q: What kind of drills are commonly used in CNC machining centers?: The drill is usually divided into high speed steel (HSS) and hard alloy (CARBIDE) according to our common material. If the machine spindle accuracy, large power, can use the alloy drill to improve processing efficiency, if considering the cost of the words of high-speed steel is cost-effective, of course, relatively low efficiency, in terms of an alloy drill to increase 1.5-3 times than the efficiency of high-speed steel drill. The advantages of alloy drilling: high hardness, wear resistance, high temperature resistance. Disadvantages: hard and brittle, improper use, prone to fracture.

Q: Use an electric drill or hammer installed TV rack?: An electric rotary hammer drill with a safety clutch with a pneumatic hammer mechanism. Hammer is the use of compressed gas piston, impact drill bit, need not make much effort, can open 6--100mm in concrete, brick, stone and other hard materials on the hole hammer in the above-mentioned materials on the opening of high efficiency, but it is not a hole in the metal.

Q: What drills do you use for screw holes?: The threaded hole form, are processed in accordance with the bottom thread needs processing, such as M24 with 21 bit.

Q: Grinding the drill bit, how can grinding, and the method of quick crash is what ah?: Deviation angle of drill shaft." Here is the relation between the axis of the drill bit and the surface of the wheel. "Frontal angle", that is, the top angle of 118 degrees + 2O half, about 60 degrees, this position is very important, directly affect the drill point size and the main cutting edge shape and cross blade edge angle. Often. One and two refers to the relative position of the drill before sharpening, and the two should take overall consideration, not to set aside the edge of the knife and ignore the angle of setting or to lay the oblique axis and ignore the blade. These errors are often present in actual operations. At this point, the drill is ready for contact with the wheel in place of the correct position.
