- 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.
- Q:Why can an electric drill pinch the drill so tightly?
- Because of the three teeth that had bitten the drill, there was a fixed steel ring. Ah, the three teeth were cone-shaped, and they rolled down, so they snapped
- Q:What kind of drilling bit is good for stainless steel?
- The characteristics of stainless steel is high toughness, easy to stick a knife. So the drill hardness is high, surface finish better than ordinary bits, the bit angle large (130--135 degrees). At the same time to the full amount of feed and cooling. More than 0.15mm as much as possible without cutting in cold hardened layer. The cutting speed is as low as possible to reduce the cutting temperature. The cutting fluid is made of concentrated emulsions. Commonly used stainless steel drills are: high cobalt bit (M35 bit, M42 bit), in which the M42 bit is the most cost-effective, and carbide drills are also available.
- Q:Do you have a drill with a diameter of 2.2mm?

- Q:What is the material composition of the electric hammer drill?
- 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:Hammer can play with an electric drill steel, can you
