- Q: Bit grinding, hair and technical requirements
- A standard twist drill is a very common drill tool. The utility model has the advantages of simple structure and convenient sharpening, but it is not an easy task to sharpen the grinding method and the skill well.Factories also have such a situation, the work of more than ten years of workers, grinding well, twist drill also quite a lot. What is the reason for this? The key is methods and techniques. If the method is mastered, the problem will be solved.

- Q: Can HSS drill bits be drilled into stainless steel?
- No, we should use alloy drill bit, drill vertex angle to 135 degrees, you can use the drill grinding machine repair grinding, our company is using Dongguan Muller machine drill grinding machine, grinding effect is good.
- Q: The basic angle of twist drill
- The back angle of the selected point on the main cutting edge of the twist angle alpha Om is expressed by the feed back angle alpha Om in the point column section. The column section is the point m of the main cutting edge, a line parallel to the axis of the drill, and the cylindrical surface formed by the rotation of the line around the center of the bit. The alpha Om changes along the main cutting edge, and the closer to the center, the greater the alpha Om. The back angle of the outer edge of the twist drill is usually 8 to 10 degrees, and the back angle of the transverse blade is 20 to 25 degrees. This can compensate for the influence of the angle of the main cutting edge on the actual working angle of the main cutting edge due to the axial feed motion of the bit, and can adapt to the change of the front angle.
- Q: How to allocate the 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 reciprocating hammer exercise. 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..
- Q: What do you mean by 5 times diameter drill?
- The meaning of 5 times diameter drill:Drill depth is 5 times the diameter of the drill bit.Double diameter refers to how many times the diameter of the meaning, mainly refers to the length of the drill bit and bore ratio, is to measure the function of the drill an important indicator, that is, the larger the diameter, the greater the depth of drilling.
- 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 causes the drill bit to break at the end of the hole?
- Small bit not used high speed, with small feed amount.A small drill can withstand torque is small, the use of high speed with a small amount of feed, can reduce the small rotating cutting output, so as not to drill to bear large torque.
- Q: What is the drill bit of the percussion drill, please?!
- Percussive drills work by rotating and impacting. Percussive drills work by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force.
