Q: M3 threaded hole. The bottom should choose large diameter drill bit: The bottom of the thread hole of the above M3 is the standard diameter of the drill bit made of ordinary materials. Of course, the actual production operation because the M3 screw mechanical properties of various materials is not the same as the processing of the material properties through appropriately adjusting, processing, such as M3 stainless steel threaded hole, must be to increase the diameter of the bottom hole processing, because the mechanical properties of stainless steel and ordinary materials are not the same. Stainless steel material hardness high, heat dissipation is poor, the reason of higher plastic, bottom diameter with a diameter of 2.7 bits. So in the actual operation, the operator should be through different material properties, adjust the threaded hole diameter of M3, so as to prepare for the next tapping.

Q: At present, the strongest oil drill bit, the deepest can drill how many meters?: Correspondingly, the specifications of ultra deep drilling machine can be divided into 6000 meters, 7000 meters, 8000 meters, 9000 meters, 10000 meters, 12000 meters and 15000 meters. The United States is the country with the longest history, the largest workload and the highest technology level in the world. It also has the largest number of deep drilling rigs. There are about more than 90 more than 9000 meters deep drilling in the world, the United States accounted for more than 80, of which 8 drilling more than 10668 meters deep.

Q: 8mm iron expansion bolts with few drilling drill mm?: It's a gross mistake to say 8 mm punching. As with a hammer smashed bolt can not. Strictly speaking, 12 mm bit should be used, but if the expansion bolt is not standard, you need to drill 10 millimeters, then twist the hole, it is best to use caliper to measure the diameter of the bolt and then decide

Q: What drills should be used to drill holes with diameter 5mm and depth 65mm? Urgent! Thank you!: You don't know what material you need to drill, what is the material, or how hard it is,Ordinary material on the ordinary line, and if the material hardness, then you have to use M35 cobalt or alloy drill.

Q: What's the diameter of the PT3/8 internal thread drill?: With the 8.1 PT3/8 drill holeThis is its nominal diameter, the actual processing, I suggest you try to make the hole bigger.

Q: What drill is best?: The general drill is HSS high-speed steel, and if a good point is high-speed cobalt containing steel, black should be treated by blackening! Black Brown should be TIALN coated!! This drill is usually not custom-made, at most, take the standard drill bit to make a TIALN coating!!

Q: What is the difference between cobalt titanium alloy drill: Is coated on the surface of the object by an electroplating method on the outside with a titanium protective layer,An element of the periodic table of cobalt chemical elements, having an atomic number of 27 and an atomic weight of 58.9332

Q: Specification of plastic expansion plug and collocation of drill bits: For domestic expansion parts, there is no size standard, so there is no way to tell you how many sizes. Plastic expansion pipe, to measure its body diameter (regardless of some special products, such as some foreign use, there will be a large part of the stay outside), due to the expansion strength of plastic parts, and the product itself is relatively small, so with the same size a bit, and not boring a bias is too large, so as not to affect the aperture.

Q: The difference between left and right drills used to drill holes: If the twist drill is said to be left-handed or right-handed, this is related to the direction of rotation of the spindle. Regular drilling machines use the right-hand bit; in some special cases, the main axis of the drilling machine rotates opposite, and the left-hand drill is required.

Q: Method for processing coolant hole of internal cooling bit: About the processing of the inner cold hole, it depends on the material and the corresponding products. In general, cemented carbide is added to the core when the mold is fixed, and then the core material is different according to the hot melt type.
