- 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: How big bits are used for expansion bolts?
- The required diameter of the expansion bolt is the same as the diameter of the expanding tube (Note: not the diameter of the bolt).
- Q: Tap is M14-H2, drill with big bit
- In practice, the thread material is different, the bottom diameter is different: Iron and steel parts are different, coarse and fine teeth are not the same, the habit of hand tapping and drilling tapping are not the same. Standard pitch M14 thread is 2, so the threaded hole diameter of 12, to select 12.20 pieces of steel, there are two kinds of specifications of fine teeth: a pitch of 1.50 or 1, the corresponding threaded hole diameter is 12.60 and 13.10.
- Q: What's the difference between a deep hole drill and an ordinary bit?

It is suitable for drilling cast iron, carbon steel, copper, aluminum alloy, alloy steel and so on. The gun drill will complete the drilling, boring and reaming at once, and at one time, the high precision (IT6-8 grade), fine straightness (0.16-0.33mm/1000mm) and low roughness (Ra3.2-Ra0.1) holes can be machined. Its drilling speed of 30-100 meters / min..

- Q: What are the main points of drill grinding?
- Make sure that the edge of the blade is symmetrical to the axis and the sides are slowly repaired. When the edge is sharpened and the other side is sharpened, the edge must be in the middle of the axis of the drill bit, and the edges of both sides must be symmetrical. The symmetry of the experienced teacher will look to the light point, slowly grinding. Drill cutting edge angle is 10 DEG -14 DEG, after large angle, the cutting edge is too thin, when drilling vibration badly, orifice in three edge or pentagon, the chip is acicular; small angle, drilling large axial force, easy to cut, the cutting force increases, temperature rise drill, severe fever, or even drilling. For after the angle grinding, the tip of two edged, symmetrical, drilling bit, chip light, no vibration, no enlarged aperture.
