Q: How many diamond grinding wheels should be used for an alloy bit?: I don't know what machine you're grinding on. Generally 120 items are enough. My clients are 120

Q: What are the weight specifications of the drill pile when the bridge pile foundation is constructed?: In terms of size, this depends on the size of the hole you want to play. Generally they are 0.8m, 1M, 1.25m, 1.5m, 1.8m.

Q: What bits of percussion drills are made of?: Features: with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.

Q: What's the difference between white, black, and yellow twist drills?: There are 3 processes for producing drills, black for rolling and worst for rolling. White for clean edges and ground. Because, unlike rolling, no high temperature oxidation, the steel grain structure is not damaged, used to drill a slightly higher hardness workpiece.

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: The maximum diameter of the hammer is fixed up? Can I open the hole? How does an electric drill screw in? How big is the drill bit?: Hammer of different sizes have different maximum diameter of the drill bit.

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: What size of drill should we use to drill 10 holes?: The use of impact drill or hammer is generally used with 8MM drill, impact drill or hammer is by shock opening principle, always maintain a bit gap state, the gap is about 2MM, and the 8MM bit size, to meet the size of diameter 10MM! If a drill is used to open holes in wood or other plates, a 10MM drill can be used without the drill bit error...

Q: What's the angle of a standard twist drill?: If the front angle is too small, the bit strength decreases, the deformation increases, the torque increases, and the drill bit breaks easily. Therefore, a reasonable front angle should be sharpened according to the strength and hardness of the workpiece material. The front angle of the standard twist drill is 2 and phi is 118 degrees

Q: Cobalt containing special stainless steel drill bit, 4mm angle, do not move?: No matter what drill, the head must be sharpened! The small drill can be struck because the front edge is well sharpened! And 8.5 of the drill bit can not drill through, because the drilling side of the two cutting edges did not grind out (front angle is lower than the back angle, resulting in non cutting! To grind to the rear corner, lower than the front corner!!!!!!!!. When the drill bit blade grinding, drilling 4mm angle, is very fast, also don't add coolant! (head color change, drill when there is a cry, two sides do not chip out, all the drill bit did not wear well), grinding drill bit is a learning, learning is not difficult. Learn to grind the drill bit and drill around with the 10mm to see the edges.
