- Q:How do you drill a bit?
- A bit, including a cutter rod, a cutter rod tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E). The orientation of the short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end. In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.
- Q:To do the M4 screw hole, what size holes must be drilled first?
- According to my experience in the industry, since you are an aluminum piece, you should use kerosene or kerosene and cutting fluid when you tap. This will make the tapping more smooth and protect the tap and thread. In addition, the general aluminum pieces should be steel wire screw, otherwise, the teeth are easily broken.
- Q:What's the difference between full mill and rolling twist drill?
- A word is not clear, the different processing technology, the high production cost of drilling grinding, rolling and drilling cost is relatively low, also has the gap, drill grinding durability is more than fifty percent higher than in the rolling, and workpiece cutting performance, drill to drill a lot, I was the production
- Q:Do you have a drill with a diameter of 2.2mm?
- Yes, of course. As long as the drill is reasonable, there is no, you can grind it yourself
- Q:What brand of drill iron?
- The key of the bit selection is not the brand, but the choice of the drill bit.
- Q:What kind of drill bits are used in glass drilling?
- Glass drilling can be made with carbide drills and diamond sand drills.

- Q:Hammer can play with an electric drill steel, can you
- The disadvantage is that the vibration is large and has a certain degree of damage to the surrounding structures. The steel bars in concrete structures can not be passed smoothly. They can not be too close to the building because of the scope of work.
- Q:Tap 10 taps, what size drills do we use?
- In general, with nominal diameter equal to the diameter of the bottom hole pitch reduction. 10-1.5=8.5, that's 8.5. However, if the quarterly demand is high, follow the formula below:D1=d-5H/8 H=0.866p:D1-- drilling diameterD - thread diameterH - theoretical height of threaded teethP - pitch
- Q:What are the main points of drill grinding?
- The edge of the drill must swing up and down, and the tail of the drill can not stand up. This is a standard bit grinding action. The main cutting edge swings up and down on the grinding wheel, that is, the hand holding the front of the drill must swing the drill bit up and down evenly on the grinding wheel surface. The handle of the hand can not swing, but also to prevent the rear handle to go up, that is, the tail of the drill can not be high above the horizontal center line of the grinding wheel, otherwise it will make the edge of the grinding blunt, unable to cut. This is the most crucial step, the drill is worn well and bad, there is a lot to do with it. At about the same time, start at the edge of the blade and rub it gently in the back, so that the back of the blade is more polished.
