- Q: Which is better, a white drill or a black drill?
- Another is between white and amber. Or above amber. This type of drill is called titanium drill, divided into decorative plating and plating industry. Decorative plating don't have any effect, is good-looking, golden. Very good industrial plating, hardness can reach HRC65 degrees, higher than cobalt drilling hardness (HRC54 degrees).
- Q: M3 threaded hole. The bottom should choose large diameter drill bit
- The bottom of the thread hole of the above M3 is the standard diameter of the drill bit made of ordinary materials. Of course, the actual production operation because the M3 screw mechanical properties of various materials is not the same as the processing of the material properties through appropriately adjusting, processing, such as M3 stainless steel threaded hole, must be to increase the diameter of the bottom hole processing, because the mechanical properties of stainless steel and ordinary materials are not the same. Stainless steel material hardness high, heat dissipation is poor, the reason of higher plastic, bottom diameter with a diameter of 2.7 bits. So in the actual operation, the operator should be through different material properties, adjust the threaded hole diameter of M3, so as to prepare for the next tapping.
- Q: Relationship between bit diameter and rotation speed
- Secondly, it is related to the grinding, feed size, material and so on. Such as: stainless steel drilling, the drill speed and feed volume should not be too large, the need for flexible use.
- Q: How big is the drill bit for the 7mm hole?
- If the big point is OK, use 6.5 bit to drill a hole, and then use 7 bit reaming, we can get 7.0-7.1 hole, directly use 7 bit drilling, the hole error is the biggest. Hope to be helpful to you, please adopt.
- 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: Why do you always burn drills?
- The drill is so small, but the depth is very shallow, so this speed can be, the knife can be calculated in accordance with the formula, appropriate to adjust the actual situation of cutting. I believe it will help you.
- Q: What do you use for drilling walls?
- The drill can drill metal wood, you want on the wall, cement, stone drilling should be used if the hammer, also called impact drill. The difference between an electric drill and an electric drill is that it has an impact when it is drilled. Its drill bit is not the same as the ordinary drill, and its drill is inlaid with alloy on the drill face.
- Q: When tapping M4, M5, M6, M8 and M10, how big bits of drill (ordinary steel) are used?
- Extrusion tap:Screw - pitch: D=d1-0.49P P = 2. In the case of M10x1.5, hole size D=10-0.49 * 1.5=9.27. (recommendation 9.3)Screw - pitch: D=d1-0.42P P = 0.8. In the case of M3x0.5, hole size D=3-0.42 * 0.5=2.79. (recommendation 2.8)Therefore, cutting tap hole were recommended as follows: 3.3, 4.2, 5, 6.8, 8.5
- Q: An expansion screw with a diameter of 20. How much impact bit do you need to use?
- An expansion screw with a diameter of 20 requires an impact drill with a diameter of 26mm.
- Q: How to use glass drills?
- The bit rotates about the vertical shaft and moves in the axial direction. The soil is cut under the action of the torque and axial force of the bit, and is crushed and crushed by the compression and centrifugal force of the working blade, forming the earth flow toward the wall and ascending to the surface along the page. When the soil flow to the pit wall barrier at the time, due to the centrifugal force around the broken soil thrown into the pit, to complete the whole process of digging.
