Q:How big is the drill bit for the 7mm hole?
If 7 holes are machined, 6.9 bit holes are used, and 7 reaming holes are used to obtain the qualified holes
Q:How much bit should we use to punch the M5 hole? Tapping with Duodasi attack? Why use 8.3 drill bit in the hole of M10? How do you know how big it is to punch and tap?
The diameter of the drill is usually marked at the drill handle. If it is not marked, it should be measured with a measuring device. M5*20 5.5 screw drilling hole is played, not the threaded hole.
Q:The maximum diameter of the hammer is fixed up? How does an electric drill screw in? How big is the drill bit?
Hammer of different sizes have different maximum diameter of the drill bit.
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:Can an electric drill bit a wall
Common electric drill: used for drilling of iron, wood, plastic, etc.;
Q:What drill is drilled on marble
Do not use impact drilling, use an electric drill, and a high-speed steel drill, which is equivalent to grinding a hole in the marble!
Q:Can twist drills drill through wall tiles?
A drill bit (Drills) is a tool used to drill through holes or blind holes in solid material and to expand existing holes. The commonly used drills are mainly twist drills, flat drills, center drills, deep hole drills and casing drills. Reaming drill and countersink drill is not in solid material drilling, but it is also customary to put them in a bit.
Q:How to recognize the quality of twist drills?
Then the heat treatment: you can simply judge the surface texture of the drill with the naked eye, which shows the good heat treatment, and the worse the contrast. Especially the black drill, some heat treatment is not in place, and black treatment is used to cover the burn of the drill. Production of the giant black diamond quality is stable, the small factory to keep in mind the black diamond.
Q:The difference between left and right drills used to drill holes
The use of left-hand drill, mostly because the machine tool design can not meet the needs of the right-hand bit, as some spindle can not meet the right-hand thread, you must use the left-hand thread. The specific situation is not practical, it is difficult to say too clear.
Q:How to use glass drills?
The bit rotates about the vertical shaft and moves in the axial direction. The soil is cut under the action of the torque and axial force of the bit, and is crushed and crushed by the compression and centrifugal force of the working blade, forming the earth flow toward the wall and ascending to the surface along the page. When the soil flow to the pit wall barrier at the time, due to the centrifugal force around the broken soil thrown into the pit, to complete the whole process of digging.
