Bits with a limiter for drywall: advantages of use

Mounting plasterboard sheets (HL), you can easily damage the product by accidentally pressing the screw. As a result, in the body of gypsum, cracks that weaken it or damage to the top layer of cardboard occurs. Sometimes the screw head passes through the gypsum board, as a result, the canvas is not fixed to the metal profile.

In any of these cases, the consequence of overpressure is the loss of strength, and hence the durability of the structure. And only a bit with a limiter for drywall will help prevent such problems.

A bit with a limiter for mounting gypsum-cardboard plates is a special type of nozzles that do not allow a self-tapping screw, when tightened with a drill or a screwdriver, damage the gypsum board.The limiter resembles a cup, the size of which is larger than the head bits. When twisting, the protective element rests against the sheet and does not allow the cap to penetrate the body of the gypsum board. Thanks to such a limiter, the master can not worry about what will happen hauling screw.

Work with the use of nozzles with a restrictive element is significantly accelerated, since the need to waste time on a constant check of the quality of fasteners disappears. The only thing that is necessary is the minimum experience and skills of working with the tool, because it is impossible to screw the screws with your own hands: for this you need to use a drill or a screwdriver.

Be aware that the limiting bits are produced for different types of materials.and this is indicated by the marking on the product. If the work will be carried out with GKL, then the nozzle should be chosen for this type of building material, otherwise the probability that the sheet will be damaged increases significantly.

You also need to make sure that the markings of the bits and caps of the screw match. Otherwise, the work will be inconvenient, in addition, screws, nozzles and even electrical equipment may be damaged.

There is no special instruction describing how to use bits with a delimiter. They are handled in the same way as with conventional nozzles designed for screwing screws into any existing material. The exception concerns only the tool on which the bit is worn. Most often to work with gypsum using a screwdriver. Drill is used extremely rarely, as it has too high revolutions, and this is fraught with damage to the GCR.

When fixing drywall sheets, it is not necessary to press very hard on the screw: as soon as the limiter touches the upper layer of the GCR, the work is terminated.

To limit the depth of the bit does not remove the notches on the caps of fasteners, you can take a model with a clutch. This nozzle envelops the bit only until the limiter comes in contact with the surface of the drywall. After that, the clamping device is disconnected, and the bit stops moving.In the screwdrivers of famous brands, a similar device is already provided.

Before screwing in, a bit with a self-tapping screw must be set clearly perpendicular to the gypsum board, and in the process of work not produce any rotational movements. Such manipulations can cause a large hole in the drywall, the quality of the fastener also does not improve, and the cost of the cladding will increase. The same principle should be applied in case of skew.

When the screw is not fixed in the profile, this may be evidence that it does not have a good enough sharpening. Because of this, it is not necessary to push the screw more strongly, even with a bat. This will cause damage to the drywall sheet, fastener cap, or even bits. You just need to take another screw.

Important! The use of bits in the creation of drywall construction has certain nuances:

• Magnetic holder will greatly simplify work using the bits. It is located between the screw and the element with the limiter.
• Check the reliability and quality of the nozzle produced by the method of "dipping". To do this, the nozzle is lowered into the box / package with screws. If one screw is stuck - such a nozzle is not a good product. An excellent indicator - three elements on a bit.
• Selection of nozzles for screwing in the gypsum board occurs only after the purchase of fasteners.

When installing a drywall system, it is difficult to do without a bat with a restrictive element. It will help to perform all the work faster, and the places where the screws are screwed in will have an aesthetic look.

So that buying a bit with a limiter is successful you need to take into account certain criteria when choosing it:

• Diameter fasteners. In self-tapping screws, which are most often used for installation of drywall systems, the diameter of the cap is 3.5 mm. For such products, the corresponding bit must be used. If the screw has a cap with an eight-pointed slot, it is better to work with a PZ nozzle.
• Length. If the installation work does not cause discomfort and occur in convenient conditions, then a long nozzle is not needed. If manipulations are carried out in hard to reach places, then the long bit will best help to cope with the task. Most often, such models are used in the construction of niches, shelves and other structures.

• The service life of the bit depends on the material from which it is produced. The highest quality alloy - chrome with vanadium. Bits from a compound of tungsten with molybdenum have proven themselves well. Special attention from the buyer deserve nozzles made in China, since the percentage of defects in such products is quite large.
• Magnetized holder - a great addition to the nozzle. With it, screws are well fixed at the end of the bits, they do not fly off, and there is no need to hold them with your hands. Therefore, it is better to choose nozzles with such an element.
