- 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: Do you have any special drill for aluminum alloy?
- There are aluminum alloy bit, select M42, M35 or 6542 bit.
- Q: What size drills and taps are required for drilling M10's internal threads?
- Internal thread drill M10 should choose the drill and tap should take into account the thread pitch. If you are a standard thread M10*1.5, thread holes should be used with 8.5 bit;
- Q: What drill is used for punching aluminum parts?
- In principle, both high speed steel and alloy alloy do.
- Q: What chisel drills are used for building water utilities?
- Don't say to yourself why, before all the impact drill plus tip and flat chisel and hammer, impact drill with open ditch, then with hammer and chisel out the middle left
- Q: What is the cause of the drilling mud bit?
- Geological factors: the drilling for upper diagenetic ooze, easy to paste on the bit surface, bit balling caused by compaction after formation of shale; although diagenesis, but easy dispersion, the borehole mud or solid content increased, adsorbed on the surface of drill bit by bit balling; or the strata containing dispersed gypsum, resulting in mud pollution, harmful solid mud in difficult to remove, the probability of bit balling is increased; the formation of high permeability, under pressure, harmful solid phase adsorption within the wellbore and cuttings did not timely carry out the formation of thick mud cake, while tripping in PDC below the drill bit caused by the accumulation of bit balling.

- Q: Carbide drills and high speed steel drills, which are suitable for working stainless steel?
- High cutting force and high cutting temperatureThis kind of material has high strength, large tangential stress and large plastic deformation during cutting, so it has great cutting force. In addition, the material has a poor thermal conductivity, which results in the increase of cutting temperature, and the high temperature often concentrates in the long and narrow area near the cutting edge of the tool, thus speeding up the tool wear.
- Q: Why not hammer drill iron
- Positive function: can make use of a wider range of electric hammer drill, the form is mainly realized through switch or adjust the brush position, usually big tools will be used to adjust the brush position (rotating brush) to achieve the benefits of doing so is easy to operate, effectively inhibit the spark to protect the commutator, prolongs the service life of the motor6, hammer drill double function: both the impact hammer, electric drill and penetration.
