Q: Can twist drills drill through wall tiles?: A drill bit (Drills) is a tool used to drill through holes or blind holes in solid material and to expand existing holes. The commonly used drills are mainly twist drills, flat drills, center drills, deep hole drills and casing drills. Reaming drill and countersink drill is not in solid material drilling, but it is also customary to put them in a bit.

Q: How do the new pros and cons drill the drill bit without the key?: This is the hand chuck chuck, is divided into two parts, the front end is used for elastic, rear end is fixed, you want to unload the drill, left to right back to the front to turn in the opposite direction can be loose, Anhui, Bozhou, great electrical firm opened, welcome patronage. Address is: Wanfu market, B building, No. 76-77, which is the general agent of broad brand. Cost-effective

Q: What drill is drilled on marble?: You can use an impact drill, use an electric drill, and a high speed steel bit, which is equivalent to grinding a hole out of the marble. There is a risk of splitting with the impact drill!!!LZ estimate your bit has problem or not will not ` ` ` ` ` ` ` ` try it

Q: What bit is better for drilling 304 stainless steel?: Drilling 304 stainless steel with an ordinary high-speed steel drill can be done, but note the requirementThe sharpening angle of the drill must not be less than 110 degreesThe angle of the drill should be symmetricalDon't be too sharp edge cutting is not easy.

Q: At present, the strongest oil drill bit, the deepest can drill how many meters?: Oil and gas drilling is divided by depth, 4500-6000 meters belong to deep well, 6000-9000 meters belong to ultra deep well, more than 9000 meters belong to special deep well.

Q: What's the difference between a deep hole drill and an ordinary bit?: What's the difference between a deep hole drill and an ordinary bit? Concretely speaking:Deep hole drilling is also called carbide gun drill, and most of the materials used are titanium, cobalt and steel. The deep hole drill is welded together by three parts of a drill stem, a drill rod and a drill bit. There is a through hole in the middle. It is suitable for drilling cast iron, carbon steel, copper, aluminum alloy, alloy steel and so on. The gun drill will complete the drilling, boring and reaming at once, and at one time, the high precision (IT6-8 grade), fine straightness (0.16-0.33mm/1000mm) and low roughness (Ra3.2-Ra0.1) holes can be machined. Its drilling speed of 30-100 meters / min..

Q: What method should we pay attention to when drilling small holes and long holes in plain drills?: When drilling a deep hole or a long hole, the workpiece must be fixed. Drill the hole with the center first, then drill with the bit so that the drill will not drill the hole when it is drilled.

Q: 14 what big expansion wire does the drill use?: The size of the bit corresponding to the expansion bolt:Bolt, =M16, drill bit, bolt diameter directlyBolt =M20, in addition to the buried depth of =170mm, take the diameter of 24mm, the diameter of the drill bolt

Q: Deep hole refers to the diameter of drill bits more than times, called deep hole: DF deep hole drilling: this kind of drill absorbs the advantages of BTA deep hole drilling and jet drilling, and uses single pipe, chip removal, pushing and suction to improve the chip removal ability, and can drill holes at the depth of 8 millimeters or more. Gun drills are usually made of high speed steel or hard alloy. Various kinds of inner chip removing deep hole drilling can be welded or mechanically clamped and indexable carbide inserts according to size. The guide block on the deep hole drill has the function of guiding and centering to reduce the deflection of the drill hole and the vibration during cutting. The arrangement of cutter teeth and guide blocks in deep hole drilling mainly considers the balance of radial forces during chip separation and cutting. The cutter body and the drill rod can be welded or square threaded.

Q: How do you drill a drill?: 2, drill clockwise in the same direction, drilling tail down about 10 degrees angle, sharpening;3, drill once rotated 30 degrees angle or slightly larger, pay attention not to sharpen all other cutting edge, grinding two or three times;The 4 supporting point does not change, and the drill rotates 180 degrees, with the same method sharpening all other cutting edges;5, after grinding, the drill will be vertical (to make it natural droop), and hold it in hand, check whether the grinding bit is symmetrical with its center line;In case of asymmetric grinding, the angle between the cross blade and the cutting edge should be 50 degrees --55 degrees;
