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: What are the differences between the center drill and the twist drill in its structure and use?: Center drill: prefabricated, precise positioning for hole processing and central hole machining on end faces of shafts and shafts. Guide the twist drill to reduce the error.

Q: How do we calculate the length of a drill for a bored pile drill?: There are two main types of drilling rigs: rotary drilling machine and impact drilling machine. The bit of rotary drill is divided into three kinds of scraper drill: suitable for quicksand and silt layer. Only the diameter and weight limit, no length limit cone drill: suitable for soft stone and hard soil. There is no length limited hob drill: suitable for hard rock layers. There are weight limit and hob arrangement, hardness requirements above, there is no drill length requirements. Impact drill: it is to use the weight of the drill to squeeze the soil into the hole, and the hole of the rock is also to use the bit itself to destroy the rock structure surface into holes. Only the weight on bit (according to the requirements of classification of rock hardness determine bit weight, diameter of 2-2.5 meters in the drill hole, the weight of at least 10 tons; 1.5-2 meters, bit weight of about 5 tons, 1.5 meters below 3 tons. For impact drilling, the length of the drill has a certain requirement, usually 1.8-2.5 meters high. Because the longer the drill bit, the stronger the impact drilling guidance function, the smaller the possibility of partial hole, hammer and hammer, the higher the standard of drilling. There are no rules and regulations, and you can succeed by experience.

Q: How to remove the electric clock bit: The outer part of the drill joint is provided with a plastic sleeve, and one hand pushes the plastic sleeve inward, and the other hand holds the drill bit to pull out the drill bit.

Q: What are the brands of homemade twist drills?: You drill stainless steel, you can try the square King's kind of fully polished red box. Iron, ordinary steel plate with yellow box. Relatively speaking, the price will be good. If you're rich, buy an old job or go to work. In addition, foreign brands in addition to M42 material is indeed not domestic, the other are domestic manufacturers processing. It has many big clients in foreign trade. Of course, you can also choose some small manufacturers of products, good luck can also buy the same quality products. Twist drill is so, set angle is greater than the material. Because I used the system to bake yellow, the square king used to drill stainless steel drilled 30 holes, so recommend it. His whole grind should work better, and the price is much more expensive than that of huang.

Q: CNC machine tools I use 6.5 bit drilling out is 6.7, what method can be solved?: Also, bit clamping and grinding will also affect the drilling size to varying degrees.Remedy is:1, the size of the hole strict requirements of the workpiece, you can drill after the hinge.2, the hole size requirements are not too strict, with 6.5 or 6.6 drill directly drilling. In mass production, the first workpiece must be measured and checked.

Q: Can HSS drill bits be drilled into stainless steel?: No, we should use alloy drill bit, drill vertex angle to 135 degrees, you can use the drill grinding machine repair grinding, our company is using Dongguan Muller machine drill grinding machine, grinding effect is good.

Q: Drill bit specifications: The drill bit is also called the engineering thin-wall drill bit.There are many models, usually from 18mm to 350mm. The length is 370. Four hundred and fifty

Q: What is the difference between cobalt titanium alloy drill: Alloy refers to two or more than two kinds of gold content are mixed together to form metal,

Q: Cobalt containing special stainless steel drill bit, 4mm angle, do not move?: The characteristics of stainless steel is high toughness, easy to stick a knife. So the drill hardness is high, surface finish better than ordinary bits, the bit angle large (130--135 degrees). At the same time to the full amount of feed and cooling. More than 0.15mm as much as possible without cutting in cold hardened layer. The cutting speed is as low as possible to reduce the cutting temperature. The cutting fluid is made of concentrated emulsions. Commonly used stainless steel drills are: high cobalt bit (M35 bit, M42 bit), in which the M42 bit is the most cost-effective, and carbide drills are also available.
