Q: Can twist drills drill through wall tiles?: To use the electric drill tile or impact drill with drill, drill bit to use glass with water, careful operation, drilling speed from slow growing fast.

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: How big bits are used for expansion bolts?: The required diameter of the expansion bolt is the same as the diameter of the expanding tube (Note: not the diameter of the bolt).

Q: How do you drill a sharpening bit?: By the back edge grinding behind. This is the slow grinding of the entire flank from the edge of the bit. It is easy to dissipate heat and grind. Based on the formula one or two to consolidate stability, this bit can be gentlyContact grinding wheel, a small amount of grinding, grinding, to observe the uniformity of the spark, to adjust the size of the pressure, and pay attention to the cooling of the drill. When the cooling start again after grinding, to set the position of the one or two formula,This is often difficult to master in the beginning, often involuntarily change the correctness of its position.Formula four: "the next swing tail don't tilt." This action is also very important during the sharpening of the drill, and the students often change the "up and down" into "up and down" in the process of grinding so that the other main blade of the drill is destroyed. withThe tail of the drill can not be raised above the horizontal center line of the grinding wheel, otherwise it will cause the edge to be dull and can not be cut.

Q: What's the difference between a flashlight and an impact drill?: The drill bits used are not the same.General electric drill is small power, drill iron sheet, drill wood whatPercussive drilling is usually made of concrete, or wall holes, the power is relatively large.

Q: What is a two center drill? What's the function?: There are two drill centers, one for passing through the bushing and one for reaming the center of diameter (the center line coincides with the center of the drill string)

Q: What size of drill should we use to drill 10 holes?: The use of impact drill or hammer is generally used with 8MM drill, impact drill or hammer is by shock opening principle, always maintain a bit gap state, the gap is about 2MM, and the 8MM bit size, to meet the size of diameter 10MM! If a drill is used to open holes in wood or other plates, a 10MM drill can be used without the drill bit error...

Q: Twist drill 200mm deep bore, what does the drill grind?: A standard twist drill is a very common drill tool. The utility model has the advantages of simple structure and convenient sharpening, but the grinding method is really good, and the method and the skill of grinding are well mastered. Factories also have such a situation, the work of more than ten years of workers, grinding well, twist drill also quite a lot. What is the reason for this? The key is methods and techniques. If the method is mastered, the problem will be solved.

Q: What is the cause of the drilling mud bit?: Engineering Technology: small displacement drilling, can not effectively cleaning the bottom and at the same time, the return speed of drill cuttings in the well, long residence time, adhered to the wall to form a thick mud cake, especially in the upper part of drilling speed is more serious; in soft rock strata, the drilling pressure is too large, or drilling stratum with the drill bit is formed on the surface of direct contact, causing bit balling; long open hole drill is not halfway through the cycle, from the mud cake wall scraping or cuttings are bit balling.
