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:How does an electric drill drill a hole on the 16mm with a 10mm drill bit?.
1. Use a ruler to measure the length of the 16MM around the wall. Mark the mark with a pen.2. Drill the drill with 10MM, drill a 10MM hole in the middle of the mark.3, with 10MM hole as the center, continue to open the drill, slowly rotating in a clockwise manner.4, rotating to the mark position, 16MM hole will be completed successfully.Remember, you can't go too far. You should take it slowly. You can turn it clockwise and counter clockwise for a while.
Q:What's the difference between a drill bit and a tap?
You have a good sense of humor. Of course the drill bit is used for punching.
Q:What's the difference between an impact drill or 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:How can the gun drill be unloaded?
Maybe you're using an impact drill. The drill can be taken as follows:1, drill up, hand drilling cap, press down hard, drilling cap down, you can pick off the drill.2, drill upward, in the upper part of the drill cap has a flat iron U shape card, pull down the U shaped card on the cylinder pin, turn to the side of the U shape card, you can pick the drill bit.
Q:What drills do you use for screw holes?
The first drilling, wire tapping in the attack. This depends on how big the screw, then bit than tap.
Q:I want to buy an electric drill with requirement is about 3MM bit penetration with ordinary bowl to eat what to buy an electric drill to much power and strength
Upstairs said good, the key in the drill bit. But the speed of the electric drill must be high, the line speed is fifty or sixty meters per second. The drill shall be ground into the negative rear angle, and no water can be added. No water can be added halfway. You can't stop over.
Q:How about the speed of the drill bit and the feed of the cutter in the machining center?
1:S= (1000 x cutting standard value) / (3.14 * tool diameter)The cutting tool standard value is supplied by the cutter supplierF according to cutting tool standard value. Measurement of feed per turn. I usually give D13 1300 RPM feed 250,2: faster than the above3:R6 knife milling 45# steel can give 800-1200 rpm F to 200-400. According to the depth to addition and subtraction.In fact, according to the formula to calculate, the feasibility is not high, you are not programmed to bring the tool standard every time, or, according to experience, it is better
Q:Sharpening of drill angle when machining different materials
Generally, when drilling soft materials, the drill is best able to wear a bit of sharp, so that the drill bit centering, and drilling out of the hole size is not too bad. But if there is no special requirement, drilling with different angles can be used to drill different materials. In addition, the drill can be drilled at different angles on the same material as needed. For example, drilling on the same material, if the size of the hole requirements are relatively strict, the drill will have to sharpen a bit, so that the drill bit of centring is better, drilling out of the hole is relatively round. But if we drill deeper holes, it is better to wear them flat so that the bits are better and the chip is removed so that the cuttings in the deep hole can be smoothly discharged. In short, it is necessary to flexibly select different drilling bits according to the actual situation.
Q:What drill is best?
Material is 6542, even better, it contains cobalt... Then coated TiAIN pure blackThe effect is better than your black brownI have a punch hereOrdinary processing around 3WAfter coating processing can do 25-30W or soThe effect is very strongThe drill you want, I can do for you. I'm from the tool factory
