Q: Tap with 5 taps. How many drills are drilled?: Drilling refers to the use of drills to drill holes in solid material. The drilling work in the exploration work, as well as the auxiliary tools needed for drilling and some emergency measures are described here.

Q: What is the maximum available drill bit for an electric drill with a maximum diameter of 10mm?: Of course, if it is not a cylindrical drill, but a hole opener, it can be as large as 100mm and open a round hole on a low density material such as a large board.

Q: Impact drill and electric hammer drill is what is the difference: Impact drill and electric hammer drill bit is different: the impact drill used, need to tighten the special key. Is the electric hammer drill for electric hammer, electric hammer drill with locking clip assembly, simple, without any tools.

Q: How can we change an ordinary drill bit into stainless steel?: Ordinary drill can also drill stainless steel, but the performance is a little bit worse, the use of cutting speed is slower, plus special cutting fluid or vegetable oil for cooling lubrication.

Q: What drills are used in tapping 304 stainless steel?: Asked to sell drill bit, stainless steel drill bit, usually they know. Our company uses cobalt cobalt bit. It's very durable and works wellIf there's anything better, I don't know.

Q: What kind of drill is drilled by 40Cr heat treatment with hardness above 40 degrees?: On the other hand, putting a blade on a large cutter is not necessarily a costly mistake. The cost of the CBN blade is 8-10 times that of the carbide blade. In the use of these advanced material blades, if the cutting speed and feed is not correct, will affect product quality and tool life. Because it is difficult to realize the stock reserve, it is necessary to evaluate the processing benefit and the whole process. Value from the whole process, if we consider the adjustment and replacement of the blade time, even if the use of carbide tools with low cost to meet the requirements of tolerances and surface accuracy, so the cost is expensive. Only when the production capacity, processing cycle and blade performance are well coordinated can the actual machining capability eventually be formed.

Q: What is the geometric angle of the drill bit?: The commonly used bit, roughly divided into rolling twist drill, full grinding drill, is divided into straight shank drills, taper shank drill and 1/2 drill, double auger, single head, short drill center drill, six angle shank drill, electric hammer drill, impact drill, the material can be divided into 4241# and 4341#. 9341#, M35, M42, 6542#, and alloy etc..

Q: Specification of plastic expansion plug and collocation of drill bits: For domestic expansion parts, there is no size standard, so there is no way to tell you how many sizes. Plastic expansion pipe, to measure its body diameter (regardless of some special products, such as some foreign use, there will be a large part of the stay outside), due to the expansion strength of plastic parts, and the product itself is relatively small, so with the same size a bit, and not boring a bias is too large, so as not to affect the aperture.

Q: What brand of drill iron?: A drill for drilling ironThe drill material is usually made of high speed tool steel or carbide, and high speed steel is often used in the factory. When drilling, it will be added coolant according to the different materials and rotating speed.
