Q: How big expansion screw does the 6mm bit have?: Expansion screw generally refers to the metal expansion screws, expansion screws fixed, but the use of wedge slope to promote expansion, friction, grip force, to achieve fixed effect. One end of the screw is threaded, and the other has taper. Outside the bread (some tin pipe), iron cylinder (steel tube) has several half incision, put them together into the wall lay the hole, then the lock nut, the nut screw pull, pull cylinder taper iron, iron cylinder is open up, so tightly fixed on the wall, generally used for protection bar, awning, air conditioning and other fastening in the cement, bricks and other materials. But its fixed is not very reliable, if the load has a larger vibration, may be loose, so it is not recommended for the installation of ceiling fans.

Q: What are the differences between the center drill and the twist drill in its structure and use?: A twist drill is a tool for cutting round holes in a workpiece by rotating it in a relatively fixed axis. It is named because of its shape of spiral groove. The spiral groove has 2 grooves, 3 grooves or more grooves, but the 2 groove is the most common. The twist drill can be held in manual, electric, hand-held drilling tools, or drilling machines, milling machines, lathes and even machining centers. Drill materials are generally high speed tool steel or carbide.

Q: How much is an alloy drill bit?: Alloy bit generally refers to the hard alloy bit, divided into integral, welded, indexable inserts and removable head.The main components of cemented carbide are tungsten carbide, cobalt, etc., the hardness is relatively high, generally above HRC90 degrees, and it is suitable for batch processing and hard processing.

Q: What bit is better for drilling 304 stainless steel?: Alloy bit generally refers to the hard alloy bit, divided into integral, welded, indexable inserts and removable head. Generally the whole tungsten alloy drill bit materials, imported and domestic alloy bit is very different. Imported alloy bit usually adopts VHM micro grain hard alloy (ISO K40), the type of ultrafine particles (0.6 m), will take the high-quality alloy bit surface coating, such as chromium aluminum nitride (AlCrN) coating, the coating layer of coating, the thickness of 4 m, the micro hardness is up to 3200HV, the friction coefficient of 0.35 the thermal stability, up to 1100 degrees celsius. After coating, the drill color is bluish gray. After coating, the alloy drill can process low alloy steel and high strength steel. High steel can reach 54HRC.

Q: 8mm iron expansion bolts with few drilling drill mm?: 8mm iron 12mm impact drill drilling expansion bolt, this is because the expansion bolt is normal, the bulk of the direction of 11MM, so we must use 12MM bit, if the use of a small number of bits, the expansion bolt is difficult in the walls, attention should be paid attention when the fastening nut screw slip.

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: How big are the 8 bits that have worked up?: If 8mm's expansion pipe uses a drill with a diameter of 8mm, if it is a 8mm expansion screw, use a drill with a diameter of 12mm.

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 drill is drilled after quenching?: Carbide coated tools can handle around HRC50 of materials, such as Mount Vickers 840, and material 1220

Q: Which material, gb1436 and 6542, has a good drill?: 6542 refers to the content of various elements in this material. For example, 6542 is W (tungsten) content of about 6%, Mo content of 5%, Cr content of about 4%, V content of about 2%.
