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 does M3x0.5 mean by tapping a drill bit?
M3 * 0.5 represents a 3 mm screw with a pitch of 0.5 mm. With a diameter of 3 minus 0.5 equals 2.5 pitch dia. It is to drill 2.5 holes with a drill, and then tap with a M3 tap.
Q:What are the brands of homemade twist drills?
. After roasting yellow, the drill looks yellow, not white or gold. In addition, what foreign doctors are actually made in China, because foreign countries have been eliminated, the total production of this product. The added value is too low. New twist cards and old brands in china. Veteran of the most stable should be Kazakhstan workers, workers. But to tell the truth, in fact, as long as the material is not deceptive, the accuracy of the geometric angle, many companies can do such a degree.
Q:What measures can be taken to prevent the bit from breaking
In drilling, the pressure must not be too great for the drilling hole to avoid breaking the bit.
Q:What drill does 42CrMo use to drill better?
Drilled outlet, rotary car hole boring other shapes
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:What is the difference between cobalt titanium alloy drill
A drill is the first part of a drill or hand drill.
Q:When tapping M4, M5, M6, M8 and M10, how big bits of drill (ordinary steel) are used?
Stainless steel, titanium alloy, steel and other materials hard to be machined: D=d1-0.95P. Still in the case of M10x1.5, hole size D=10-0.95 * 1.5=8.575. (recommendation 8.6)
Q:Cobalt containing special stainless steel drill bit, 4mm angle, do not move?
No matter what drill, the head must be sharpened! The small drill can be struck because the front edge is well sharpened! And 8.5 of the drill bit can not drill through, because the drilling side of the two cutting edges did not grind out (front angle is lower than the back angle, resulting in non cutting! To grind to the rear corner, lower than the front corner!!!!!!!!. When the drill bit blade grinding, drilling 4mm angle, is very fast, also don't add coolant! (head color change, drill when there is a cry, two sides do not chip out, all the drill bit did not wear well), grinding drill bit is a learning, learning is not difficult. Learn to grind the drill bit and drill around with the 10mm to see the edges.
Q:Sharpening of drill angle when machining different materials
For the sharpening of the drill, we should grind the drill at different angles according to the needs of the drilling. For example, a bit of drill bit drilled to a relatively hard material can grind larger (i.e. flat);
