- Q:How do I take out an electric drill bit?
- Drill bit: with a key, insert the key into the side hole of the drill sleeve and loosen the bit to remove the bit.
- Q:How to use glass drills?
- The bit rotates about the vertical shaft and moves in the axial direction. The soil is cut under the action of the torque and axial force of the bit, and is crushed and crushed by the compression and centrifugal force of the working blade, forming the earth flow toward the wall and ascending to the surface along the page. When the soil flow to the pit wall barrier at the time, due to the centrifugal force around the broken soil thrown into the pit, to complete the whole process of digging.
- Q:Use an electric drill or hammer installed TV rack?
- Wall drilling in modern buildings is more suitable for use with percussive drills, so installation of impact drills is recommended when installing a television rack. Suitable for drilling hammer in cement material.
- Q:What drill is used in stainless iron drilling?. What color?
- The best is to make the stainless steel material of cobalt containing material with high speed steel drill, high-speed steel drill is cobalt containing silver, do not know the landlord of the silver white bit is not high speed steel containing cobalt, if not, you can buy only high speed steel cobaltiferous material drill (also called stainless steel special under the best bit), buy imported, not much of your money, the quality difference is too large domestic drill. Or if not, can change the drill bit Ti, Ti is abrasion resistant, average life is 3 times more than the standard twist drill
- Q:What kind of drill is drilled by 40Cr heat treatment with hardness above 40 degrees?
- The cost of the blade is relatively low, and the cost of cemented carbide blade is about 3% of the total processing cost,CBN blades are reinforced and guided, and they can prevent edges from chipping when machining materials with a hardness of more than 50RC.CBN blades make up 5-6%, so using cheap blades is a wrong way to save money. The use of advanced materials in the short term can recover the investment, and the waste rate is very low.
- Q:What are the brands of homemade twist drills?
- General twist drill rolling and grinding, high quality grinding, I used, there are good brands in the processing of steel parts on the whole: drill, drill Gongquan full amount, mine drill, drill the Far East
- 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:What's 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:Types of impact drills
- There are two types of drill hole two groove round handle (usually produced abroad and anti hammer production abroad is used), four hole square shank (general domestic production of electric hammer used) and five bit six bit long pit, angle etc.. Hope to be of help to you.
- Q:What are the main points of drill grinding?
- Grind back from the edge of the blade. When the blade is in contact with the grinding wheel, it should be drawn back from the main cutting edge, that is, contact the grinding wheel from the edge of the drill bit and then slowly grind down the whole flank. Gently contact wheel bit penetration, advanced for less grinding, and observe the uniformity of discharge, timely adjustment of the size of the pressure on the hand, but also pay attention to the drill bit cooling, can not be allowed to wear too much, causing the edge to edge discoloration, annealing. When the blade temperature is high, the drill bit should be cooled in time.
