- Q:What bits of percussion drills are made of?
- Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals.
- Q:How do you determine the speed of the drill? Is there any standard?
- Different diameter of the drill bit, drilling speed, diameter smaller, higher speed, otherwise low;
- Q:How big expansion screw does the 6mm bit have?
- Expansion screw generally refers to the metal expansion screws, expansion screws fixed, but the use of wedge slope to promote expansion, friction, grip force, to achieve fixed effect. One end of the screw is threaded, and the other has taper. Outside the bread (some tin pipe), iron cylinder (steel tube) has several half incision, put them together into the wall lay the hole, then the lock nut, the nut screw pull, pull cylinder taper iron, iron cylinder is open up, so tightly fixed on the wall, generally used for protection bar, awning, air conditioning and other fastening in the cement, bricks and other materials. But its fixed is not very reliable, if the load has a larger vibration, may be loose, so it is not recommended for the installation of ceiling fans.
- Q:The threaded hole M5 general drill big bottom
- 1. for brittle materials (steel, copper etc.) bottom: 5-0.8=4.2mm.2. (for cast iron, bronze, aluminum) plastic material bottom: 5-1.1 * 0.8 = 4.1mm or 4mm can.
- Q:How do the front and back angles of the drill change? How does it affect drilling?
- The front angle mainly affects the feed rate of the drill, which is determined by the hardness and abrasiveness of the metal.The rear angle mainly affects the cutting, cutting, the central axial force, reducing the force surface, so as to reduce wear.
- Q:What's the difference between a UC drill and an ST bit?
- The ST drill is easy to operate, easy to control diameter, more grinding times, and its range of use is relatively large. It can be used in general use, which is beneficial to general diameter drilling and double face plate and more than 6 layers of panels.
- Q:Drill hammer type matching specifications
- Hard alloy electric hammer drill body made of high quality alloy steel, the knife head is welded with hard alloy. Matched with various electric machine, concrete, brick and other building materials for hard drilling. The utility model is a drilling tool with wide use and high efficiency in the construction and installation industry.
- Q:By drilling with a bit, why is the hole drilled straight 2 larger than the diameter of the drill?
- Drill bit, drill out of the hole than the drill diameter, because drilling cuttings will increase the extrusion aperture; at the same time, for the convenience of a chip it is necessary to improve bit will increase; if the concentricity is not good, it will increase more.
- Q:How does an electric drill drill a hole in 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 bit is hard, not easy to wear and punch?
- Stainless steel drilling bit, not the problem, of course, is not Never mind, is to buy a bottle of vinegar, vinegar, vinegar is vinegar can be, not tried.
