Makita Drill How To Insert A Drill
What a repair would do without a good drill and a set of drills! However, even the most reliable tool during operation can jam. Do not rush to panic! We will teach you how to change a drill in a drill and correctly diagnose other breakdowns.
Drill device. What you need to know about the tool?
Jamming of the drill in the drill chuck or screwdriver took place at least once with each owner of the tools. To understand why this can happen, you need to figure out how the drill is arranged. This tool converts electrical energy into mechanical energy, which is possible thanks to an electric motor that spins the shaft. Through the gearbox and gears, the rotation is transmitted to the fixture, in which the drill is fixed.
Now consider the operation of an electric drill on the reverse side, provided that the drill was fixed incorrectly or not tightly enough. Fluctuations that occur during operation will lead to deviations in the direction of drilling, as a result you will get a curved hole. Vibrations from vibrations will be transmitted to gears and a reducer, they will hook the shaft and the engine itself. This does not threaten damage immediately, however, a reduction in the life of the tool is guaranteed! Often negligence when fixing the drill and leads to jam. Sometimes jamming occurs as a result of the drill slipping from the drilling point. To avoid this, use a spring punch to make recesses on the surface for the drill.
In addition to jamming, a loosely fixed drill can pop out of the fixture, and this is already fraught with severe injuries for the person working with the tool and those around it, given the speed of modern devices. Therefore, never fasten the drill in a hurry, always disconnect the drill for this from the current, in order to avoid accidentally starting the drill.
Mounting device. Non-combat cartridge
A chuck is called a fixture in which a drill is fixed. The fastener itself is screwed onto the tool spindle. Most often, drills are equipped with a cam chuck. This design is a hollow cylinder with metal “fingers” inside. When you turn the adjusting ring, which is located outside the node, the “fingers” converge or diverge along the inner conical surface. In such a “fist”, you can clamp both a drill with a cylindrical shank and a hex.
Convenience and ease of use have made the cam mechanism popular. However, it is not without flaws. One of them is the difficulty in working with small drills. A short product can simply fall inward. It is still possible to fix it by putting the drill in a horizontal position, but it is impossible to press on it strongly during operation. If another drill has been inserted into the drill, it can be removed by turning the adjusting ring in the appropriate direction. It’s not always possible to do it manually, for this there is a special key that acts like a lever, increasing effort. By the way, tightening the drill without a key is also not recommended. The larger the diameter of the drill, the more reliable the fastening should be.
When buying fasteners, make sure that it is rubberized. So you will less injure your hands when securing the tool.
The work of quick-clamp fasteners. The second most popular. Is possible without a key. It is enough to insert a drill and turn the lever, often this can be done with one hand. The fixation of the drill, which this type of cartridge provides, is quite enough for most work, however, in comparison with the classic mounting option, it is inferior in reliability, and is more expensive. The main advantage of quick-clamping is the speed of the drill replacement and the safety of the process, since such a cartridge is devoid of teeth that can injure hands. The absence of a specialized key is also a significant advantage! Experienced builders know how easy it is to get lost, so very often you can see the key with an attached tape or tape to the wire.
True, this does not add convenience, but there is at least some confidence that the key will not have to be searched throughout the construction site. How to change a drill in a screwdriver? The scheme is absolutely identical. The chucks of most drills are similar to the fasteners on screwdrivers. Of course, the last tool cannot be a complete replacement for a quality drill, if only because fasteners are not designed for drills with a large diameter, and the speed of the screwdriver is usually less.
How to change a drill in a drill. Do it yourself!
Not always the drill can be pulled out of the chuck in the usual way. As a result of a heavy load or improper fixation, it can jam the chuck. How to get a drill from a drill without damaging the hardware and tool itself? First of all, try to cool the cartridge well. Sometimes this is already enough for the cams to release the drill bit a bit and you can pull it out.
The most proven way to remove a stuck tool is by tapping the fists. To do this, the free end of the drill is fixed in a vice, a wooden plank is applied to the chuck, through which tapping is carried out. From such vibration, the cartridge can loosen its grip and release the tool. This method is useful to both owners of classic fasteners and owners of quick-clamping. Sometimes removal is possible after lubricating the drill with machine oil or the popular WD-40 grease.
The latter method is better, because due to the sprayer the substance will reach the desired points of contact between the drill and the cartridge faster. In any case, after lubrication, you will need to wait a bit for the substance to penetrate deeper. Sometimes, in especially difficult cases, the problem is solved only after dipping the entire cartridge in machine or vegetable oil. If neither one nor the other is at hand, you can make a “bath” of your drill and gasoline. Keep the cartridge in the liquid for at least an hour. When combining methods, you get the jammed drill even faster.
How to replace a cartridge. We update a drill
Often than not, the cartridge comes into disrepair first in a drill. Dismantling it at home is not easy, but possible! The fastener is screwed onto the spindle itself, but in addition it is still fixed with a bolt with left-hand thread. In order to get it, you need to completely unclench the cartridge. It is inside. The whole difficulty of unscrewing it is that many do not know about left-hand thread, and trying to unscrew it, twist it even more, tear off the hat and, as a result, carry it to the service.
Unscrewing the bolt, you can unscrew the cartridge itself, however, and this is not so easy to do. In some models, at the base of the thread there are recesses for a wrench. In this case, you can fix the spindle and unscrew the fasteners, using a lot of effort. The real difficulty arises when there are no wrench sections. You will have to remove the housing cover to fix the spindle inside the drill. Difficult, but doable.
To remove a cartridge is one thing. To pick up a new one is quite another. In addition to the methods of clamping the drill, which are described above, different chucks also have different threads! The surest way to not confuse anything is to take the old cartridge with you and show it to the seller, or how to choose the right one according to the layout. When you coped with this task, all that remains for you is to screw the cartridge onto the spindle and tighten the bolt, which in our case is twisted counterclockwise.
