Q:What do you mean by 5 times diameter drill?
The meaning of 5 times diameter drill:Drill depth is 5 times the diameter of the drill bit.Double diameter refers to how many times the diameter of the meaning, mainly refers to the length of the drill bit and bore ratio, is to measure the function of the drill an important indicator, that is, the larger the diameter, the greater the depth of drilling.
Q:The difference between steel teeth and inserted cone bit
The bits in the underground work after a certain time, drag bit blade diameter became small, short, blunt, the rock breaking ability becomes weak, slow progress; roller bit tooth wear due to erosion, bearing damage, will cause the cone roller rotation is not flexible or stuck, so that the torque increased, if not timely play that will happen cone off accident; diamond bit due to formation heterogeneity caused by PDC bit on the occurrence of crack, break, drop, also make slow drilling footage. In order to speed up the drilling of the whole well, the old bit must be replaced in time
Q:What chisel drills are used for building water utilities?
Now is the use of play slot machine, before impact drill plus pointed and flat chisel and hammer.1, can use the slotted line pipe cutting machine, can also use the shovel,2, the most simple and practical way to slot the box is to use diamond in the groove where the direct drilling,3. The diameter of the hole is determined by the size of the wire box. For example, 86 of the wire boxes can use 100 of the drill bits.4. The depth of the wire box is the depth of the borehole.5, knocking out a hole in the middle of bricks and then trimming.6, such open line box groove position standards, size appropriate, also easy to use mortar filling fixed.
Q:What's the material composition of the electric hammer drill?
Electric hammer drill, mainly adopts the high quality alloy steel, the cutter head adopts Y hard alloy welded.
Q:M6 screws should drill big holes
1.M6 need to drill 4.8mm hole thread. Calculation method:2. generally speaking, the diameter of the Gong bolt multiplied by 0.86 is the diameter of the hole to be drilled.3.M6 thread refers to the nominal diameter of 6mm coarse tooth common thread.
Q:What kind of steel do you need to drill?!
Drills are usually made of cemented carbide. The so-called carbide is based on tungsten carbide powder as a matrix, cobalt powder as binder, by compression and sintering. Usually containing tungsten carbide 94%, cobalt containing 6%. Because of its high hardness, very wear-resistant, has a certain strength, suitable for high-speed cutting. But the poor toughness, very brittle, in order to improve the performance of the hard alloy, with some hard carbide titanium carbide substrate in chemical vapor deposition of a layer of 5 to 7 microns (TIC) or titanium nitride (TIN), which has higher hardness.
Q:What size drills are we going to use to drill the holes in the M7 and with the larger twist drills?
M thread, the twist drill is used to represent theIf the hole drill with M7 drill bit is 6.5, you can use M7 taps.
Q:What drill is used for machining holes with a diameter of 3mm?
In general, if the drill pointed to the comparison of the grinding, it is recommended to be smaller than the final hole 0.10mm, of course, this is the processing of steel parts, plastic and other processing holes will shrink back, generally take a little larger diameter. If the final size of the strict requirements, it is best to drill rough, such as 2.5 of the drill bit, and then 2.8-2.9 drill reaming, and finally reaming, precision reaming, usually with 3.0mmD5-D6 class. Drill what specifications have, in general, the first series of multi-point, second, third series less, large dosage, you can find manufacturers custom. Can not find the words, you can buy a larger diameter of their own in centerless grinding or grinding on the outer circle to change, but the effect will be worse, the drill has inverted cone, not necessarily grinding, and need experience.
Q:Electric hammer drill killed what should take down
Electric hammer drill, is the "two function drill" and "hammer" handheld electric tool, "rotary cutting drill", with the impact of the impact mechanism of driving impact drill bit, drill driven in rotation at the same time, there is a direction perpendicular to the rotation of the rotary drill reciprocating hammer exercise. For concrete, brick, tile, marble and other materials drilling. "Hammer" to drive the impact force of drill rod, used for concrete, bricks and other materials on the slotting, holes or broken concrete etc..
Q:How to use glass drills?
The drill bit is clamped on the ordinary hand drill, and the finger is used to select the lower speed of the switch. If you want to drill holes will not collapse, then drill a part from the side, and then turn over the surface drilled through.
