- Q: Why is the drill angle 118 degrees?
- HSS high speed steel drill bit: vertex angle is generally 118 degrees, sometimes greater than 130 degrees, HM carbide drill bit: vertex angle is generally 140 degrees; straight groove drilling is often 130 degrees, three edge drill is generally 150 degrees.
- 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: Is there a standard for drilling errors due to machine tool shaking?
- Is the drill drill a positive or negative deviation, or is it bigger or smaller?. Bit wear is not serious, the drilled hole is a positive deviation. If the drill is used for a long time, the ligament is worn badly and the drill is worn out too, and the hole drilled is a negative deviation
- Q: What is the difference between steel and high-speed steel?
- Tungsten is a kind of high speed steel was non alloy steel containing tungsten before, now use less, there are people on the use of power tools. Before the steel generally used for ordinary tool making hand taps, drills, saws and cutting speed is relatively low, the hardness is about 60~63HRC. High speed tool steel is now divided into low alloy, high performance and other types, widely used in the manufacture of various cutting 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: Do you have any special drill for aluminum alloy?
- Aluminum alloy, copper, stainless steel, the hardness of these materials are not high, aluminum alloy, copper soft, frequent drilling process, easy to cut, and there will be a lot of burr. The best choice for some Aluminum Alloy drill bits for different materials when drilling drill main cutting edge angle will be different, the best selection of aluminum cutting angle of 120-135 degrees, the feed is not too high, due to the low, if the best friend can understand the material selection of M42, M35 or 6542, not bad bit a few drill does not move. The bit is divided into a rolling bit and a full grinding drill, and the whole grinding drill is 30% more expensive than the rolling mill, but the effect is much better than that of the rolling mill.
- 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: 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: Grinding the drill bit, how can grinding, and the method of quick crash is what ah?
- Deviation angle of drill shaft." Here is the relation between the axis of the drill bit and the surface of the wheel. "Frontal angle", that is, the top angle of 118 degrees + 2O half, about 60 degrees, this position is very important, directly affect the drill point size and the main cutting edge shape and cross blade edge angle. Often. One and two refers to the relative position of the drill before sharpening, and the two should take overall consideration, not to set aside the edge of the knife and ignore the angle of setting or to lay the oblique axis and ignore the blade. These errors are often present in actual operations. At this point, the drill is ready for contact with the wheel in place of the correct position.
- Q: How do we drill a tile with a thickness of 5mm glazed, without a glass bit, only the impact bit? What's up? The brick is attached to the wall!
- If the tiles under not hollow cement, Tim is very full, can not grasp, if you should buy a special tile bit, namely triangular bits, it does not produce tremor phenomenon, easy positioning, cut resistance, opening soon, there are the ordinary chuck used on an electric drill to need to pay attention to slow speed in particular, is just beginning to open and slow speed when wearing. When in use, add coolant (not too much, but keep adding water). Drilling can be done on hard materials such as glass, stone and tile. 3MM-16MM have, but don't drill edge or side (away from 2 cm above tile seam), or to use the glass or diamond drill hole, is used to watch the speed slower (800-1000 revolutions per minute or so), continue to water cooling (don't need too much, but continue to add water) non dry drilling! High temperature friction, causing serious wear and tear, affecting the use effect!
