- Q: New drills usually need sharpening before they can be used. Why?
- What you say does not exist, the new drill is not heavy grinding can be used; cutting edge is yes, the front angle is the drill bit of the spiral groove angle, it is impossible without the front angle, and the back angle is not 0 degrees, the peak angle is not big. It's only in the drilling that produces what I said before, so it's time to rub it again and use it again.
- Q: What steel blade drill bit, hardness above 60
- 1, steel blade with steel drill bit.2, steel alloy steel is a kind of complicated, containing tungsten, molybdenum, chromium, vanadium carbide forming elements. The total amount of alloy elements is about 10 to 25%. It can maintain high hardness at high temperature (about 500 DEG C) in high speed machining, and HRC can be higher than 60. This is its main characteristic - red hardness, which can be used to make cutting tools. The Rockwell hardness of tungsten series and molybdenum high speed steel can reach over 63 after proper heat treatment. Because the steel is too hard, so can not bend, a love fold, it is difficult to punch.
- Q: What's the difference between a twist drill and an impact drill?
- A twist drill is a tool for cutting round holes in a workpiece by rotating it in a relatively fixed axis. It is named because of its shape of spiral groove. The spiral groove has 2 grooves, 3 grooves or more grooves, but the 2 groove is the most common. The twist drill can be held in manual, electric, hand-held drilling tools, or drilling machines, milling machines, lathes and even machining centers. Drill materials are generally high speed tool steel or carbide.
- Q: How do the new pros and cons drill the drill bit without the key?
- There are two ways to unload and unload manually:Methods: hand unloading drill drill handle on the ground, pine along the direction of the drill bit to find a hard thing with the hammer hit, the release, remember that it is right to bear left loose, otherwise it will be more and more tightly card.The method of using a card or key to pry it open:(1) card: the electric drill is lifted and the clasp is removed to remove the drill bit;(2) bevel key: remove the bit by pressing the key with an anti clockwise ring, then the drill ring can be taken out.
- Q: 1 inches of steel plate, what drill can drill through?
- 1 cm steel plate? 5 cm steel plate, I have drilled, with ordinary drill, you own improper operation, steel plate to be fixed, must not move, do not force too much, the speed is not too high!
- Q: The maximum diameter of the hammer is fixed up? Can I open the hole? How does an electric drill screw in? How big is the drill bit?
- Put the drill will bite at the top of the hand claw loosen, the drill bit is put into a plug in the end, and tighten with the special wrench, if the old hammer, was struck with an iron wedge bite claw hammer with teeth to tighten the drill.
- Q: How big is the screw hole at the back of the torch chuck? Is it a rebound?
- Usually around M5 or M6.
- Q: Good or good tungsten cobalt steel drill bit.
- Tungsten bit high hardness, wear resistance. Suitable for occasions with high hardness, uniform material and no vibration (such as steel and hardened steel). That's the principle.
- Q: Carbide drills and high speed steel drills, which are suitable for working stainless steel?
- High cutting force and high cutting temperatureThis kind of material has high strength, large tangential stress and large plastic deformation during cutting, so it has great cutting force. In addition, the material has a poor thermal conductivity, which results in the increase of cutting temperature, and the high temperature often concentrates in the long and narrow area near the cutting edge of the tool, thus speeding up the tool wear.
- Q: Why not hammer drill iron
- Electric hammer drill (electric hammer drill), is the "two function drill" and "hammer" handheld electric tool, "rotary cutting drill", with the impact of the impact mechanism of driving impact drill bit, drill driven in rotation at the same time, there is a direction perpendicular to the rotation of the rotary drill the reciprocating motion of the hammer. For concrete, brick, tile, marble and other materials drilling. "Hammer" to drive the impact force of drill rod, used for concrete, bricks and other materials on the slotting, holes or broken concrete etc..
