- Q: What is the maximum diameter of the drill bit 1500W heavy hammer
- 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's the difference between a twist drill and an impact drill?
- Percussive drills work by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force. Used of natural stones or concrete. When the impact drill works, the drill chuck is provided with an adjusting knob, which can be adjusted in two ways: an ordinary hand drill and an impact drill. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, but the impact is far less than the hammer. It is not suitable for drilling reinforced concrete.
- Q: I want to buy an electric drill with requirement is about 3MM bit penetration with ordinary bowl to eat what to buy an electric drill to much power and strength
- At present, domestic electric drill clamping diameter to 10mm. The power in the 300W-750W range, but also with positive and reverse stepless speed, to your requirements for the use of 300W single direction can speed drill start steady good control, the price is slightly high. When punching to clamp is glass hole, mounted on an electric drill, follow light pressure in vertical direction, and the water cooling in the drill point. Main point: the workpiece must be fixed to the vertical force, the drill hole can not be aware of, suddenly shaking or will cause cracking of porcelain. For bulk opening, the best selection of drill. Optional hand drill type: J1Z-6A 230W 6mm J1Z-10A 300W the clamping diameter; and the clamping diameter above 10mm; J1Z-FF02-6A 230W reversible variable speed clamping diameter 6mm; JIZ-FF-10A reversible variable speed 300W and above the clamping diameter of 10mm. Add water tools can be an empty beverage bottle, a small hole in the bottle cap, after irrigation, gently pinch the bottle body, the water will be shot to the drilling hole, it is best to operate two people in order to ensure safe and smooth.
- Q: Do we need drill bit for cast steel drilling?
- Drill wood. Drilling holes on wooden materials, combined with the use of woodworking bit, woodworking bit sales volume, the hardness of the tool is not high, the tool material is generally high speed steel. There is a small sharp point at the center of the drill bit, and the angles on both sides are relatively large, even without angle. For a good fixed position. In fact, drilling with metal drills can also drill wood. Because wood is easy to heat, brittle is not easy to come out, so we must slow down, often exit, remove brittle debris.
- Q: Is there a standard for drilling errors due to machine tool shaking?
- There is no standard for the drill hole error due to machine tool shaking.
- Q: How do you get yellow on the surface of the drill bit?
- One is simple plating, and the other is complicated surface treatment, such as ion sputtering
- Q: Angle action and characteristics of standard twist drill
- Front angle gamma Om (since the front surface of the twist drill is a spiral surface, the front angles of the points on the main cutting edge are different. From the outside, the center angle decreases gradually. The rake angle at the nose point is about 30 degrees, and about -30 degrees near the cross edge. The front angle on the cross edge is -50 degrees to -60 degrees.
- Q: What steel blade drill bit, hardness above 60
- A diamond bit is a drill bit for cutting edges. The drill bit is an integral bit, the whole drill bit has no moving parts, the structure is relatively simple, with high strength, high wear resistance and impact resistance, it is one of the three new drilling technologies in the world in 1980s. Field use shows that the diamond bit in the soft - hard strata drilling, have the advantages of high speed, more footage, long service life, stable operation, less accidents, downhole wellbore quality etc.. The diamond bit not only can be used for a long time, but also can be reused. The diamond bit recovered from the factory can be used almost as well as the diamond bit produced by the factory. It can save drilling cost in large amount.
- Q: Grinding the drill bit, how can grinding, and the method of quick crash is what ah?
- The edge of the wheel is fixed by the blade." This is the first step between the bit and the grinding wheel. It is often the case that the blade has not been settled so that it is sharpened by the grinding wheel. It must be hard to wear. The "edge" here is the main cutting edge, and the "cut out" means the main cutting edge of the grinding part is in the horizontal position. "Wheel surface" refers to the surface of the grinding wheel. "By" means slowly moving closer. The drill cannot contact the grinding wheel at this time.
- Q: What drill is drilled after quenching?
- Carbide coated tools can handle around HRC50 of materials, such as Mount Vickers 840, and material 1220.
