The masonry bit is a variation of the Twist Drill Bit, the bulk of the Tool is a relatively soft steel, and is machined with a mill rather than ground. An insert of tungsten carbide is brazed into the steel to provide the cutting edges.

No matter how high the trick is, it can't escape the electronic eye monitoring.
Safe driving is the key
Can an electronic police be easily escaped? Yesterday, the reporter interviewed Zhengzhou City Traffic Police Detachment Engineer of Transportation Research Institute Li Hui. Li Hui analyzed the top four tricks in the post, and expressed that the online high-money business is unreasonable, and consciously observing the law is the best trick.
Goal 1: Remove focus circles on the license plate
Experts: From the point of anti-counterfeiting, no focus can
The license plate has a small dot. It is made of rare earth metal and emits a microwave signal. Its role is to focus on the electronic eye. Therefore, if you drop it, the electronic eye can't figure out the license plate number. You can use double-sided adhesive to glue it.
Expert: The white dot on the license plate is just a separator, and it also has a certain anti-counterfeiting effect. There is no focus at all, and it is nonsense to get rid of the dot to prevent the electronic police. If you get rid of the license plate, you can not only avoid the electronic police, but it will become the target of the traffic police.
Gao Tiao 2: 3 seconds after the red light is turned on Experts: The electronic eye will start when the red light is turned on
In order to prevent accidental shooting, 3 seconds after the red light is on, the electronic eye photographing system is started; and when the green light is on, the system is turned off 2 seconds earlier. Therefore, many taxis grab the lights, is to grasp the delay time to wipe the ball. Experts: Since 2006, Zhengzhou has violated traffic signals in violation of the law. It is actually 3 seconds after the red light is on. However, given that the driver has drilled this hole, the traffic police department has already debugged some of the intersection’s electronic police systems. The red light is on and the electronic police system is activated. There is no delay in the post.
Gao Tiao 3: Can't move experts after the car pressure cordon: Illegal, no matter where I stopped
According to the post, the intersection with an electronic eye has buried an inductive coil under the cordon, and the tire will press the coil and trigger the pulse. If two pulses are generated during a red light cycle, they will be shot. Simply put, when the red light is over, the front wheel is over and the rear wheel is not pressed, it only produces one pulse. When there are no two consecutive pulses, no picture is taken. As a result, someone had crossed the front wheel and wanted to go back. It was always OK. Wrong, back, and triggered a pulse, triggering a photo shoot. However, it was all right. There were three forensics photos, including a red light, a violation of the ban on the right, and a violation of the ban on the right. There was one body over the cordon, one on the way to the middle, and one on the crossroads. line. So, even if you trigger a photo shoot, then you don’t even stop, or if you stop outside the cordon on the opposite intersection.
Experts: At present, the electronic police at each intersection in Zhengzhou City does use the trigger mechanism of the geomagnetic coil, but this is not what the text says. An array of coils is buried in front of the general cordon, and a magnetic field is generated after conduction. A pulse is generated when the metal body passes through. Several groups of coils accurately determine the type of illegal behavior through logic. According to the relevant traffic regulations, it is necessary to confirm that one vehicle is in violation of the red light requires two photographs, the first one is to display the state in which the body of the vehicle does not cross the parking line under the condition of the red light, and the second one is to display the condition that the body completely leaves the parking line. Therefore, it is illegal to stop where it is useless.
Goal 4: Bypass can avoid electronic eye expert expert: advanced electronic eye can monitor multiple lanes
The electronic eye has a shooting range. A camera usually shoots only one lane, and a few can take two lanes. It is usually located on the first and second lanes counting from left to right. Therefore, it is possible to avoid the electronic eyes by walking around the side lanes, or to drive on the middle of the two lanes so that neither side will be photographed. This is most useful when changing lanes.
Expert: There is indeed such a problem, but now some advanced electronic police can simultaneously monitor two-way 4 lanes, that is, 8 lanes. In some road sections, right-turn lanes and even non-motorized lanes are under surveillance. Therefore, if you want to turn red lights from right-turn lanes or non-motorized lanes, it will not work.
At present, the electronic police has been installed in major cities such as Shanghai and Beijing. As Zhengzhou continues to optimize and upgrade system equipment, it is not ruled out that such electronic police will be deployed in the future.
In addition, the traffic police department will occasionally change the location of the electronic police camera or increase the number of cameras in order to monitor different lanes. Conscious compliance with traffic regulations is the best way to avoid punishment.
Masonry bits typically are used with a Hammer Drill, which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the Drill Bit tip, and the rotating flutes carry away the dust.
Hammer drill bits often use special shank shapes such as the SDS type, which allows the bit to slide within the chuck when hammering, without the whole heavy chuck executing the hammering motion.
Masonry bits of the style shown are commonly available in diameters from 3 mm to 40 mm. For larger diameters, core bits are used. Masonry bits up to 1,000 mm (39 in) long can be used with hand-portable power tools, and are very effective for installing wiring and plumbing in existing buildings.
Recently, a post titled "The Must-read for Drivers: The Secret of the Electronic Police Works" appeared in major forums such as Shangdu BBS and Tianya Community, with a high click-through rate. The author claimed to be an insider and analyzed the electronic police's photographing principle to the point where the driver was able to escape the law of the electronic police.
