- Q:Specification of plastic expansion plug and collocation of drill bits
- General use of drilling bit is slightly smaller than the expansion plug specifications, with 3.8 4 mm drill bit expansion plug can. If is the same specifications for concrete especially hard objects, if a bit drilling specifications, pulling the hammer a little shake.
- Q:How do you drill a drill?
- 2, drill clockwise in the same direction, drilling tail down about 10 degrees angle, sharpening;3, drill once rotated 30 degrees angle or slightly larger, pay attention not to sharpen all other cutting edge, grinding two or three times;The 4 supporting point does not change, and the drill rotates 180 degrees, with the same method sharpening all other cutting edges;5, after grinding, the drill will be vertical (to make it natural droop), and hold it in hand, check whether the grinding bit is symmetrical with its center line;In case of asymmetric grinding, the angle between the cross blade and the cutting edge should be 50 degrees --55 degrees;
- Q:Want to buy a hammer, with the decoration of the house, how much more appropriate aperture
- Hammer can be used to punch a hole in the concrete on the wall, is not suitable for drilling metal or wood. So the best choice is to choose the multifunctional electric hammer, hammer or hammer drill drill two functions of peace. The utility model can be used as an electric drill in a horizontal drilling file, can be opened on metal or wood, and can also be used for screwing off screws when installing a cabinet. The hammer on the market are the basic functions of.
- Q:How can we change an ordinary drill bit into stainless steel?
- I've never heard of it, but it seems to be a high-speed steel drill, and it's not expensive. Why do you charge for that?
- Q:How big bits are used for expansion bolts?
- Know the expansion bolt diameter, can find out the tube diameter; the borehole diameter is slightly greater than the diameter of expansion pipe can be used, and expansion pipe of the same diameter aperture is slightly larger than the drill out tube diameter.
- Q:How do the front and back angles of the drill change? How does it affect drilling?
- The front angle mainly affects the feed rate of the drill, which is determined by the hardness and abrasiveness of the metal.The rear angle mainly affects the cutting, cutting, the central axial force, reducing the force surface, so as to reduce wear.
- Q:How much bit should we use to punch the M5 hole? Tapping with Duodasi attack? Why use 8.3 drill bit in the hole of M10? How do you know how big it is to punch and tap?
- If the material soft bottom be slightly smaller, so hard to be slightly larger. As the aluminum tapping hole to drill small, alloy steel tapping will be slightly larger. M5 has a pitch of 0.8, so use 5-0.8=4.2's drill. The pitch is 1.5 M10, normal use 8.5 bit, if 8.3 words may be used as the material of soft, normal bit will lead to larger hole.
- Q:What's the diameter of the PT3/8 internal thread drill?
- With the 8.1 PT3/8 drill holeThis is its nominal diameter, the actual processing, I suggest you try to make the hole bigger.
- Q:What's the difference between a drill bit and a drill bit?
- That bit, drill iron is generally the middle point (force, wear to feed); wood drilling is generally three sharp edge, high in the middle and low on both sides (soft wood, such as drill faster, on both sides of the edge can also make the drill mouth flat appearance, also known as plate drilling).
- 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.
