Q:Hammer can play with an electric drill steel, can you?
The disadvantage is that the vibration is large and has a certain degree of damage to the surrounding structures. The steel bars in concrete structures can not be passed smoothly. They can not be too close to the building because of the scope of work.
Q:What is the difference between a flashlight and an impact drill?
An electric drill can drill holes in various metals, woods, plastics, etc.. Because of stone, brick, concrete is hard and brittle properties of metal and bit strong wear on these materials requires the use of drilling drill, drill hammer (hammer) inlaid with hard alloy with high hardness, impact drill impact and rotation (as with the drill rod drill in as the rock), while on one hand, the stone became a little bit to be cut down into a hole. If you use ordinary drill in drilling stone or concrete, ordinary drill blade will soon be blunt to scrap, and rotation is the impact of improving the drilling efficiency.
Q:By drilling with a bit, why is the hole drilled straight 2 larger than the diameter of the drill?
The drilling depth - to determine the guiding edge and drilling parameters of the drill: shallow ordinary drill, a set of parameters, if more than 10 long deep hole diameter ratio, cooling the drill bit will choose to guide blade, and soon after the first slow step feed, with 2 sets of parameters, the other through hole, then reduce the parameters in the proposal through;
Q:What steel blade drill bit, hardness above 70
A diamond bit is a drill bit for cutting edges. The drill bit is an integral bit, the whole drill bit has no moving parts, the structure is relatively simple, with high strength, high wear resistance and impact resistance, it is one of the three new drilling technologies in the world in 1980s. Field use shows that the diamond bit in the soft - hard strata drilling, have the advantages of high speed, more footage, long service life, stable operation, less accidents, downhole wellbore quality etc.. The diamond bit not only can be used for a long time, but also can be reused. The diamond bit recovered from the factory can be used almost as well as the diamond bit produced by the factory. It can save drilling cost in large amount.
Q:Is the drill fast to feed, easy to break, or slow to feed, easy to break?
The drill bit is fast to slow to feed off constantly does not matter much, mainly is the workpiece to be fixed, fixed, easily broken drill bit is tilted, fast heating feed is not easy to burn a bit empty, but also from the new rules, the drill bit, drill feed uneconomical, slow hair less heat, drilling accuracy high
Q:What bit is hard, not easy to wear and punch?
The drill is worn and can be grinded by a bit. We are using the Muller's drill and grinding machine. The effect of grinding the drill bit is very good.

Q:Why not hammer drill iron?
Motor protection device: comprehensive in use will inevitably have hard granular access to a machine (especially on the machine to work on drilling, such as drilling on the top wall), if there is no certain motor protection, rotating at high speed can easily be hard break or scratch enameled wire, eventually lead to the motor failure.
Q:M3 threaded hole. The bottom should choose large diameter drill bit
What do you not know about screw diameter reduction? M3 the pitch is 0.5, that is, 3-0.5=2.5.. If it is a piece, it can be larger. Choose 2.55 to 2.6 of the drill bit. All other materials are 2.5.
