- Q: What drill heads are used to drill holes in diamond heads?
- A drill bit (Drills) is a tool used to drill through holes or blind holes in solid material and to expand existing holes.
- Q: How big expansion screw does the 6mm bit have?
- 6mm drills are generally equipped with 5mm expansion screws (the smallest specification).The relationship between the drill bit and the expansion screw is the drill diameter = the expansion screw diameter +2mm. For example, the expansion screw of 6mm shall be opened with 8mm drill 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?
- Pile system refers to the construction site by mechanical drilling steel soil compaction or human mining method in the foundation pile hole in form, and placed in the steel cage, pouring concrete piles and made, in accordance with the different drilling method, grouting pile can be divided into cast-in-place pile, bored pile and digging pile and other types of. Bored pile is a kind of pile type defined according to the method of pile formation.
- Q: Is it OK to drill holes on tiles with an ordinary bit? Will the tiles crack?
- An electric drill must, of course, be of good stability. It is a small vibrating one, and the stability of the new one is better than that of the old one.When you drill, take it easy and slow down.The position is not a problem. I've drilled both the middle and the edge. Please be sure to be slow and slow!
- Q: What's the difference between a UC drill and an ST bit?
- The ST drill is easy to operate, easy to control diameter, more grinding times, and its range of use is relatively large. It can be used in general use, which is beneficial to general diameter drilling and double face plate and more than 6 layers of panels.
- Q: What are the tools, drills, and any of the machine tools made of?
- High speed steel means containing more tungsten, chromium and aluminum alloy elements such as the tower of metalwork of steel, commonly known as steel or stainless steel.The machine is characterized by simple manufacture; high hardness (63 ~ 66HRC), wear resistance and heat resistance (about 600 - 660 C); have sufficient strength and toughness; have good craft; can bear greater impact; tool manufacturing complex shape, such as special lathe tool, milling cutter and drill, broach and gear cutter; but notIt can be used in high speed cutting. Grades and properties of commonly used high speed steel.The hardness of high speed steel after quenching is HRC63 ~ 67, and the red hard temperature is 550 ~ 600 DEG C, and the allowable cutting speed is 25 ~ 30m/min.The bending strength and impact toughness of high speed steel is high, can be cast, forging, welding, heat treatment and machining, has good grinding performance, the grinding quality is high, so it is used to manufacture complex shape of tools, such as drill, reamer, milling cutter, and also used for low speed machining tool and forming turning tool.Commonly used high-speed steel grades are W18Cr4V and W6Mo5Cr4V2 two.
- 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: What steel blade drill bit, hardness above 60
- 1, steel blade with steel drill bit.2, steel alloy steel is a kind of complicated, containing tungsten, molybdenum, chromium, vanadium carbide forming elements. The total amount of alloy elements is about 10 to 25%. It can maintain high hardness at high temperature (about 500 DEG C) in high speed machining, and HRC can be higher than 60. This is its main characteristic - red hardness, which can be used to make cutting tools. The Rockwell hardness of tungsten series and molybdenum high speed steel can reach over 63 after proper heat treatment. Because the steel is too hard, so can not bend, a love fold, it is difficult to punch.
- Q: What is the cause of the drilling mud bit?
- Engineering Technology: small displacement drilling, can not effectively cleaning the bottom and at the same time, the return speed of drill cuttings in the well, long residence time, adhered to the wall to form a thick mud cake, especially in the upper part of drilling speed is more serious; in soft rock strata, the drilling pressure is too large, or drilling stratum with the drill bit is formed on the surface of direct contact, causing bit balling; long open hole drill is not halfway through the cycle, from the mud cake wall scraping or cuttings are bit balling.
