- Q: What steel blade drill bit, hardness above 60
- It is recommended to use steel bit, two hundred to three hundred RPM (8mm below the hole, more than 8mm, and then reduce speed), pay attention to cooling, the amount of feed should not be too large. For reference only, I hope it will help you.
- Q: Why is the drill hole drilled out of the hole triangular?
- Generally, the center grinding errors of the drill bits are different. The drill material with large drilling thickness is big bore, and the drill plate appears triangular hole. The best drill bit is three edged thin grinding tip, smooth drilling burr less. The first grinding drill, or need to have master demonstration is better.
- Q: How do I take out an electric drill bit?
- Impact drill: the impact drill upside down on the ground (bit up), hold down the left hand down the root of the drill drill sleeve, the right hand holding the drill bit upward, provided when rotating around a bit can be taken out.
- Q: With what drilling steel
- Tungsten steel (hard alloy) with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
- Q: M6 threads need to drill much bottom?
- A spiral shaped continuous raised part having a specified cross section on the surface of a cylinder or cone. According to its parent thread shape is divided into cylindrical and conical screw threads; according to their position in the matrix is divided into outer and inner thread, according to the section shape (teeth) divided into triangular thread, rectangular screw, trapezoidal thread, serrated thread and other special shape screw.
- Q: Why can't the tap be nitrided? Drill bits are available.
- Tap can be treated by nitriding, often used in cast iron aluminum castings. The effect of nitriding is to increase hardness. Wearable ~!
- Q: What do you mean by 5 times diameter drill?
- 5 times a bit is the drill depth that can reach 5 times the diameter of the drill. For example, a drill with a diameter of 10 can process 50 deep holes.
- 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 size drills and taps are required for drilling M10's internal threads?
- M10*1.5 (not considering tap tap for precision thread); if M10*1.25, with Phi 8.7 bit; M10*1.25 (without considering precision tap tap thread); if it is M10*1, with 9 bit;
- Q: M6 screws should drill big holes
- M6 screw, installation of air hit 6.5~7 mm in diameter was 5 mm drill tapping hole.After the general drilling drill hole due to beating, slightly more.
