- Q: How to change the drill bit of impact electric drill?
- Install the drill bit: or the handstand impact drill, the left hand down to the plastic ring, the right hand with the drill, rotating around the insertion
- Q: 1 inches of steel plate, what drill can drill through?
- Mainly used in drilling machines, lathes, flashlights and other mechanical equipment for the processing of different diameter aperture. Generally speaking, twist drills are straight shank and taper shank twist drills. Straight shank drill: suitable for drilling diameter psi below 13.0mm small diameter, taper shank twist drill for aperture and torque big hole.
- Q: How to recognize the quality of twist drills?
- The drill industry is a mixed bag, but only for experienced people.

- 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: What's the difference between a drill bit and a tap?
- You have a good sense of humor. Of course the drill bit is used for punching.
- Q: The basic angle of twist drill
- The helix angle, the beta helix angle, is the angle between the most outer spiral line of the drill bit spiral groove and the axis of the drill bit. Since the lead of each point in the spiral groove is the same, the helix angle of the drill bit at different diameters is different, the helix angle at the outside diameter is the largest, and the closer the central helix angle is, the smaller the helix angle is. Increasing the helix angle increases the rake angle, which is beneficial to chip removal, but the drill bit stiffness decreases. The spiral angle of a standard twist drill is 18 to 38 degrees. For smaller diameter bit, the spiral angle should be smaller to ensure the rigidity of the drill bit.
- Q: What size drills are we going to use to drill the holes in the M7 and with the larger twist drills?
- M thread, the twist drill is used to represent theIf the hole drill with M7 drill bit is 6.5, you can use M7 taps.

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.
- 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.
