- Q: New drills usually need sharpening before they can be used. Why?
- We monitor only a bit grinding blade; another edge to teach short, and a big pot. The hole is 60 millimeters deep; this is called a folk prescription, and the drill hole is asymmetric. The hole will appear in the big hole. If there is any deviation between the two sides of the deep hole, the drill will be drilled
- Q: Types of impact drills
- There are two types of drill hole two groove round handle (usually produced abroad and anti hammer production abroad is used), four hole square shank (general domestic production of electric hammer used) and five bit six bit long pit, angle etc.. Hope to be of help to you.
- Q: What are the differences between a twist drill and a construction drill? Where are they used?
- Impact drills operate by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force. Used of natural stones or concrete. When the impact drill works, the drill chuck is provided with an adjusting knob, which can be adjusted in two ways: an ordinary hand drill and an impact drill. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, but the impact is far less than the hammer. It is not suitable for drilling reinforced concrete.
- Q: Woodworking drills, classification, woodworking drills are those categories, the more specific the better
- Because the wood is soft, so in the material above, generally choose easy processing brand S45C.However, some foreign countries use high-speed steel to manufacture woodworking drills in order to improve the tool efficiency.
- Q: How many diamond grinding wheels should be used for an alloy bit?
- I don't know what machine you're grinding on. Generally 120 items are enough. My clients are 120
- Q: Relationship between pump pressure and bit pressure drop
- The pump pressure is the total pressure loss of the circulation system, including the ground manifold, the internal pressure loss of the drill pipe, the annulus pressure consumption and the bit pressure drop. A pump is a machine that transports liquids or pumps liquids. It transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. Pump is mainly used to transport water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid gold
- Q: Tap is M14-H2, drill with big bit
- In practice, the thread material is different, the bottom diameter is different: Iron and steel parts are different, coarse and fine teeth are not the same, the habit of hand tapping and drilling tapping are not the same. Standard pitch M14 thread is 2, so the threaded hole diameter of 12, to select 12.20 pieces of steel, there are two kinds of specifications of fine teeth: a pitch of 1.50 or 1, the corresponding threaded hole diameter is 12.60 and 13.10.
- Q: To do the M4 screw hole, what size holes must be drilled first?
- According to my experience in the industry, since you are an aluminum piece, you should use kerosene or kerosene and cutting fluid when you tap. This will make the tapping more smooth and protect the tap and thread. In addition, the general aluminum pieces should be steel wire screw, otherwise, the teeth are easily broken.
- Q: How can we change an ordinary drill bit into stainless steel?
- I've never heard of it, but it seems to be a high-speed steel drill, and it's not expensive. Why do you charge for that?
- 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..
