Q: What is the maximum diameter of the drill bit 1500W heavy hammer: An electric rotary hammer drill with a safety clutch with a pneumatic hammer mechanism. Hammer is the use of compressed gas piston, impact drill bit, need not make much effort, can open 6--100mm in concrete, brick, stone and other hard materials on the hole hammer in the above-mentioned materials on the opening of high efficiency, but it is not a hole in the metal.

Q: Why is the drill hole drilled out of the hole triangular?: Drill bit too, two edge to the machined surface in contact angle and surface processing due to too large to cutting into bite cut,Do you like to take the knife to cut wood, and wood knife angle is close to parallel cutting more labor-saving and machine power led to the great bit angle is in itself lead to tremble bit hardtop surface triangular or pentagonal in inappropriate situations

Q: What's the difference between a drill bit and a drill bit?: That bit, drill iron is generally the middle point (force, wear to feed); wood drilling is generally three sharp edge, high in the middle and low on both sides (soft wood, such as drill faster, on both sides of the edge can also make the drill mouth flat appearance, also known as plate drilling).

Q: With what drilling steel: Tungsten steel (hard alloy) with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.

Q: What measures can be taken to prevent the bit from breaking?: Especially in the hole is drilled, the drill tip has been exposed to the bottom surface, the feed speed must be slowed down, feed pressure must be reduced. In addition, if the drill is not fast, do not force to continue to use, so that the most likely to break the drill bit.

Q: Bit grinding, hair and technical requirements: A standard twist drill is a very common drill tool. The utility model has the advantages of simple structure and convenient sharpening, but it is not an easy task to sharpen the grinding method and the skill well.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's the difference between an impact drill and an ordinary electric drill?: An electric drill is a drilling machine that uses electricity as power. Is the power tools in the conventional products, but also the largest demand for power tools products. The electric drill is only available in the form of rotation, especially for drilling on materials that require little force, such as cork, metal, brick, tile, etc.. Just rely on the electric motor drives the drive gear to increase the strength of the drill bit rotation, do scraping in metal, wood and other forms of perforated material.

Q: What brand of drill iron?: The key of the bit selection is not the brand, but the choice of the drill bit.

Q: Why do you always burn drills?: Do not add cutting fluid is difficult to control, do not burn, there is no way to use compressed air blowing it will be better, and drill down when the knife properly, will be better.

Q: What kind of steel do you need to drill?!: Drills are usually made of cemented carbide. The so-called carbide is based on tungsten carbide powder as a matrix, cobalt powder as binder, by compression and sintering. Usually containing tungsten carbide 94%, cobalt containing 6%. Because of its high hardness, very wear-resistant, has a certain strength, suitable for high-speed cutting. But the poor toughness, very brittle, in order to improve the performance of the hard alloy, with some hard carbide titanium carbide substrate in chemical vapor deposition of a layer of 5 to 7 microns (TIC) or titanium nitride (TIN), which has higher hardness.
