Drywall screwdriver

The widespread use of drywall in repair work has led to the fact that many "dirty" and labor-intensive processes are in the past. Most of the rough finishes, as well as many designer designs, are now available for DIY. It is very troublesome to assemble a relief installation, sheathe walls and ceiling using a conventional screwdriver, controlling the fixation of each screw. To simplify and speed up this process, as well as to avoid damage to the material, the use of a special nozzle on a drywall screwdriver will help.

Which bits are suitable for drywall: slot and size selection

Nozzles for a screwdriver vary in shape and size, the most popular of them are marked with PH and PZ and differ in the geometry of the slots.

1. The edges of the PZ bits are strictly parallel, which ensures rigid centering and fixation of the screw head.
2. RN nozzles are distinguished by a small divergence of the slots. This allows the tool to self-center even when it is at an angle. When excessive force is applied, the edges of such a nozzle pop out of the self-tapping head without damaging it.

The size of the bits for the screwdriver is determined by the diameter of the cap used fastener. When working with drywall, standard black self-tapping screws with a diameter of 3.5 mm and a cross-shaped slot are usually used, which corresponds to nozzle No. 2.

Conclusion: for the installation of GKL, a bit is suitable for a screwdriver with the marking PH2.

Limiter nozzles

When attaching a drywall sheet to a profile, two polar problems often arise:

• uncompressed self-tapping screw will protrude above the surface;
• pinched - it can damage the plate or pass through it, which means it will not fix it on the frame.

To avoid such situations, it is worth using bits to install a drywall screwdriver with a limiter. Such a device will provide immersion fasteners to the required depth.

The limiter is a steel cartridge, at some point resting against the panel and preventing the further movement of the self-tapping screw. The use of such a device ensures accuracy and high quality work. In addition, the time spent on installation is reduced by 50%, since the need to control the screwing depth of each screw disappears.

Note! Bounding bits are highly specialized devices designed for strictly defined materials, an improper device will damage the rather fragile GKL plates.

Tape nozzle

Sometimes when they talk about a nozzle on screwdriver, designed for GKL, do not mean a bat, but a special device for automatically feeding self-tapping screws, which is worn on an electric tool. After that, he can successfully replace the tape screwdriver, which allows to accelerate the installation of gypsum plasterboard at least 2-3 times. When working with this device, self-tapping screws are used on the tape, so the master is relieved of the need to take a new screw each time, put it on a bit, correct and hold it.

What happens if you choose the wrong bit?

The choice of this, at first glance, simple device should be approached carefully and carefully. An improperly selected device can cause a lot of trouble to the master. In addition to the improper material of the limiter, you can make a mistake with the shape of the splines of the nozzle, which will cause the following problems:

• disruption of the slots of the self-tapping screw, the replacement of which takes time;
• damage or unreasonably rapid wear of the bit itself;
• lack of centering and fixing of the self-tapping screw on the nozzle;
• damage to the screwdriver itself.

Rules for choosing a good nozzle

Comfort, speed and the final result of the installation of drywall constructions directly depend on the quality of the restrictive bit. It’s easy to choose the right device, it’s enough to follow some rules:

• The bit on the screwdriver is selected for the used fasteners, but not vice versa.
• For standard self-tapping screws with a cap diameter of 3.5 mm and a crosswise slot, the PH2 nozzle is suitable.
• If the slot of an eight-beam screw - it is necessary to use a PZ bit of a nominal size.
• "Advanced" devices are equipped with a magnetic holder that helps optimize the process and increase assembly comfort.

Advice! You can check the quality of the magnet by placing the nozzle in the "handful" of screws. If the extracted bit will take with it three or more fasteners, everything is in order, it will be convenient to work with such a device.

• High-quality bits can differ in a corrugated surface, which also provides increased traction with a self-tapping screw.
• Depending on the geometry of the structure being constructed, the length of the nozzle is selected. In the case of GKL sheathing of walls or ceiling, a standard bit with a limiter is sufficient. If a niche, arch, shelf is mounted, it is better to choose an elongated nozzle.

• The service life of the device is determined by the material of manufacture. Bits containing the following alloys are considered durable: chromium – vanadium, chromium – molybdenum, and tungsten – molybdenum.
• The quality of components is also determined by the manufacturer. No matter how tempting the difference in cost may look and no matter how great the temptation to save, it is better to choose a trusted manufacturer.

If the work with drywall is not limited to the construction of partitions, but involves large volumes, it makes sense to use nozzles with an additional coating.

• Titanium - Adds resistance to mechanical damage.
• Nickel - provides protection against corrosion.
• Carbide and tungsten - increase strength.

Instead of a special nozzle, you can purchase a special adapter-bit holder with a limiter.

The use of high-quality tools, accessories and consumables is the key to the expected result. The use of a suitable bit with a limiter for a screwdriver for gypsum plasterboard provides a high level and speed of operation, allows you not to waste time and resources on replacing damaged sheets and fixtures. Uniform reliable fastening gives the necessary strength and rigidity of the structure, and special components help to cope with your own hands without any special preparation.
