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:Is it OK to drill holes on tiles with an ordinary bit? Will the tiles crack?
An electric drill must, of course, be of good stability. It is a small vibrating one, and the stability of the new one is better than that of the old one.When you drill, take it easy and slow down.The position is not a problem. I've drilled both the middle and the edge. Please be sure to be slow and slow!
Q:What drill is used for machining holes with a diameter of 3mm?
For the steel parts which require fine matching, it is recommended to drill holes with a twist hole smaller than 3mm and then drill with a 3mm bit to ensure the accuracy of the hole. As for plastic, cardboard or copper material, the aperture will be retracted. The drill bits which are slightly larger than the diameter of 0.10mm are generally used. If the machining requirements are strict, it is better to drill rough first. For example: first drill with 2.5mm bit, and then use 3mm bit reaming, so that you can guarantee the accuracy of aperture.
Q:What steel blade drill bit, hardness above 60
1, steel blade with steel drill bit.2, steel alloy steel is a kind of complicated, containing tungsten, molybdenum, chromium, vanadium carbide forming elements. The total amount of alloy elements is about 10 to 25%. It can maintain high hardness at high temperature (about 500 DEG C) in high speed machining, and HRC can be higher than 60. This is its main characteristic - red hardness, which can be used to make cutting tools. The Rockwell hardness of tungsten series and molybdenum high speed steel can reach over 63 after proper heat treatment. Because the steel is too hard, so can not bend, a love fold, it is difficult to punch.
Q:The installation method of the electric hammer drill?
Installed before the first drill, electric hammer drill chuck down below the eye in the end, the drill chuck and eye separation (and when necessary to drill chuck on the eye piece to mention) will be inserted in the end bit to the eyes, and then release the chuck let it return. After installed, the lift hammer bit hard top on the wall or ground test drilling, if a clear sense of the impact that the drill bit installed in place. Otherwise you'll have to reinstall it.
Q:How to change the drill bit of impact electric drill
Install the drill bit: or the handstand impact drill, the left hand down to the plastic ring, the right hand with the drill, rotating around the insertion
Q:What kind of drill bits are used in glass drilling?
In the drilling, the drill bit is subjected to impact loads of high frequency, and subjected to torsion, bending, stretching, compression and other complex stress, corrosion and wear in high speed rotary collision environment subjected to rock, rock powder and mineral water as working medium.Emery is one of the silica crystals. It's a kind of industrial polish.
Q:What steel blade drill bit, hardness above 70
1, steel blade with steel drill bit.2, steel alloy steel is a kind of complicated, containing tungsten, molybdenum, chromium, vanadium carbide forming elements. The total amount of alloy elements is about 10 to 25%. It can maintain high hardness at high temperature (about 500 DEG C) in high speed machining, and HRC can be higher than 60. This is its main characteristic - red hardness, which can be used to make cutting tools. The Rockwell hardness of tungsten series and molybdenum high speed steel can reach over 63 after proper heat treatment. Because the steel is too hard, so can not bend, a love fold, it is difficult to punch.
Q:Drill hammer type matching specifications
Four, five, six pit pit angle shank hammer respectively with four pits, five pits, six angle shank drill.
Q:What do you use for drilling walls?
The hammer can drill the wall. An electric drill is out of the question. Electric drill, electric hammer, impact drill is used to punch the hammer, generally used to drill holes in the concrete and other hard objects, the drill bit is alloy steel, in drilling at the same time, the function of a hammer. An electric drill is used to drill holes in a more malleable object; the drill bit is usually steel. Both hammer percussion drill and drill function, it can be used when the hammer drill, and when.
