Q:How do you drill a bit?
Less grinding, first of all, "do not rub", get the drill, that is, grinding, certainly blind grinding. This is a very important step to lay a solid foundation for grinding the next step only when you put a good position before sharpening. The teacher in the demonstration process, according to the methods and skills of practice summed up in simple formulas form explanation and demonstration, students often listen to understand, to do the normal operation demonstration, step by step action demonstration, slow motion model, so that the students easy to accept. Here the use of four formulas to guide the grinding process. Better effect.
Q:How big is the screw hole at the back of the torch chuck? Is it a rebound?
The bore of the torch chuck is a thread free bore with a degree of indentation. It is tight fit and not spinning!The drill chuck is in threaded buckle! Commonly used electric hand drill bit within 6 mm diameter 8 mm individual chuck Cocker!! 12-16 mm drill!The hole on the side of the chuck is the drill bit, the key, the axle hole, and no thread!
Q:What drill is used for machining holes with a diameter of 3mm?
At the same time, it is difficult to guarantee the absolute symmetry of the two main cutting edges because of the small bit. Generally, it is necessary to control the secondary angle of the blade edge at 6 degrees to 8 degrees. The speed is between 1000~1500, and the feed is low, otherwise the drill is easy to break or damage. The emulsion should be cooled during processing.
Q:How big are the 8 bits that have worked up?
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: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:When tapping M4, M5, M6, M8 and M10, how big bits of drill (ordinary steel) are used?
Stainless steel, titanium alloy, steel and other materials hard to be machined: D=d1-0.95P. Still in the case of M10x1.5, hole size D=10-0.95 * 1.5=8.575. (recommendation 8.6)
Q:How big a drill bit does the M6 screw hole need?
The international standard drills, 2 kinds of classification, is a national standard, such as Phi 7.6 Phi 7.2 Phi Phi 6.4 is a 6 inch according to distinguish, the common British 3/8, which is converted into a 1 inch diameter is =25.4MM 3/8*25.4= converted into China in millimeters in diameter.
Q:What bit is better for drilling 304 stainless steel?
Recommend two bit, a cobalt high speed steel drill, a kind of high performance cemented carbide drill bit, cobalt high speed steel prices, but the short life, low efficiency, poor accuracy, need to pre order centering drill better; hard alloy drill special stainless steel price expensive, but also life a lot of high efficiency, high precision of hole size, also, finish too high a lot, without centering drilling machining, can be directly used cobalt alloy drill drilling; compare the two contrast, characteristics of stainless steel is high toughness, easy to stick a knife. So the drill head hardness is high, the main component is hard alloy tungsten carbide, cobalt, hardness is generally high in HRC90 degrees, cutting fluid with emulsion concentration. The cutting speed is as low as possible, because the 304 stainless steel easy drilling so as to reduce the temperature for heating chip.
Q:What's the difference between an impact drill and an ordinary electric drill?
Professional on the wall, concrete, stone top drilling, and multifunctional electric hammer, adjusted to the proper position with appropriate drill can replace the ordinary electric drill, electric use. The hammer is using bottom motor drives two sets of gear structure, a realization of it drill, and another one is to drive the piston, a hydraulic engine stroke, resulting in a strong impact force, along with drilling results. Strength can split rocks into gold.
Q:Is the drill fast to feed, easy to break, or slow to feed, easy to break?
The drill bit is fast to slow to feed off constantly does not matter much, mainly is the workpiece to be fixed, fixed, easily broken drill bit is tilted, fast heating feed is not easy to burn a bit empty, but also from the new rules, the drill bit, drill feed uneconomical, slow hair less heat, drilling accuracy high
