Many people notice that when purchasing a screwdriver, you can get a number of additional parts in the kit. Screwdriver bits are a common addition to kits. It is better to understand this in advance and purchase what is required during operation. Not everyone knows what screwdriver bits are commercially available and what they are used for.
Slotted
Bits have several classifications. But each with its own purpose and scope. Screwdrivers for a straight slot have been known to craftsmen for many years. There are, respectively, and bits. They come with the designation S. After that, a marking in the form of a number is added near the letter. This is the width of the screwdriver bit. There are other additions as well. It all depends on the manufacturer.
Slotted screwdriver bits are no less in demand today than before. If we turn to the classics, then everyone will see the designation of the width in the range from 3 to 9 millimeters. The thickness is not indicated, because it goes in the generally accepted indicator up to 1.6millimeter. In addition, such types should have additional protection and a long service life. The next option is a slotted bit with titanium nitride. This is a type of coverage. In addition to additional protection against corrosion, the width increases to 6.5 millimeters. On sale, such additional elements are marked TIN. Their thickness reaches 1.2 millimeters.
Screwdriver bits have another look. This is a longer form, without which it is difficult to perform some work. These include subtle and precise processes. Such a nozzle sits tightly inside the screw. The length can reach up to 10 centimeters. It is difficult to do without some elements when performing the simplest work. Therefore, everyone tries to get several different screwdriver bits.
Cross bits
This is another kind. Such products began to be in demand not so long ago. This is because the standard ones may not be up to the task. They just jump out of the hat. As a result, the work performed is of poor quality and a waste of time. But after a while, more convenient bits were invented. In the store they are labeled RN. Each fastener has its own thread, so as not to be mistaken, there are digital indicators. There are values that look like this:
- 0-2 mm.
- 1-3mm.
- 2-5 mm.
- 3-7mm.
- 4-7.1mm.
There are those bit patterns that are most often used. These include an indicator up to 4 millimeters. And here is the most common size forscrewdriver bits are 2 mm. They are most often suitable in the process of household work. And in production, craftsmen use 3 and 4 millimeters to a greater extent.
The best is a cross-shaped drill bit. They are used frequently, so there are many manufacturers on the market who are ready to provide such models. When buying, you should pay attention to the additional coating that can significantly increase the life of the bit. In the hardware store, you can meet the following abbreviations:
- PH – 1.
- PH – 2.
- PH – 3.
Often in the process of work, situations may arise when it is difficult to get to the fasteners. For this, elongated cross-shaped bits are commercially available. As a result, any (even an old fastener) is unscrewed quickly and without problems. There is a standard size. The length can reach up to 150 millimeters.
Pozidriv – PZ, this is another marking on sale. They are perfect for woodworking. Masters prefer to put them when working with furniture. There are differences, and they are expressed as follows:
- The edges of the working surfaces are parallel.
- One thickness all the way.
- Deep slot level.
When the process of screwing in any fastener begins, the tool goes tight, after which maximum protection is created. This is a good bit for a screwdriver, which you cannot do without on the farm. But when creating a personal assortment, it is worth considering the need for one oranother element. There is no need to collect parts that are not useful in the process.
PZ and notches
Some manufacturers make notches on them. But what are they for? Thus, the level of wear is reduced. Going to the hardware store, you can find bits with additional coating. This is necessary so that their service life does not end after a short period of time. Such nozzles can be of non-standard length (up to 15 centimeters). Difficult situations do not always arise in domestic conditions, but in the process of assembling furniture there are corners that are not always easy to get to with standard tools. For work and personal use, they come in handy, but not always. It is worth paying attention to this when collecting a set of screwdriver bits for personal use.
Unique nozzle shape
Another option is a hexagon. It appeared in the 20th century and is in demand today no less. It is labeled HEX. What is the advantage of such an element? This is the ability to adjust the distance between the sides of the hex sting. In addition, the tools have additional reinforcement so that spontaneous removal does not occur during operation, which happens with heavy loads on the screwdriver. This is a protective slot, in the center of which there is a pin, and there is a designation.
Most often, hex bits with an indicator from 1.5 to 10 millimeters are used in work. This is enough to screw in the screw. They first appeared in Europe and gradually found their way to other countries. Sometimes the manufacturer makes morewide inner opening. Due to this, in the process of performing work with a screwdriver, the fasteners do not come out and remain in place. These bits are up to 6 millimeters in size.
As usual, in the range of hardware stores there may be elongated hexagons with their own markings. They allow you to cope with any task. But in home use they are not always useful, but they are made of high-quality material, which prolongs the service life. But the length is not too big - up to 10 centimeters.
What do you need to produce household appliances?
Star bits are models that are mainly found in mechanical engineering and in the creation of household appliances. How to find them? They can be recognized by the following designations: T or TX. A number appears next to the letter indicator, indicating the size of the nozzle. The classic variation of this bit is most often used in European countries, because it has a high level of reliability.
The star shape grips the fastener well and it screws in effortlessly. Since the nozzle has six edges, slippage is completely excluded, the screwdriver shows its work as correctly and quickly as possible. In addition, such bits do not wear out in a short time. Most often, users purchase models TX8 - TX40. They are the most convenient to use, reviews say.
You can also find tools like Torx Plus. The main difference is the presencethe asterisk has sharp corners, although they are less than the standard in length. But in the process of working with them, you need to be extremely careful, the steel is taken reliable and strong. But in terms of size, this type of bit is standard.
When going shopping in a specialized store, it is easy to find models based on high-quality material, as well as elongated ones. But why do many manufacturers use additional coatings? Of course, the cost of this increases slightly, but the service life becomes longer. For home use, such a bit is not always required in a set with a screwdriver. Sometimes there is an enlarged hole inside. This allows you to make the level of fastening reliable and of high quality. In production, it is difficult to do without such species; for the home, you can not buy.
Magnetic bat
Magnetic screwdriver bit makes the change process quick and easy. It is for personal use that many make a choice in favor of such an element. Today, a screwdriver has become indispensable in the household. But according to the forms there is a conditional classification:

Also, the work surface has its own marking, according to which the choice is made. Without understanding this, it is difficult to choose the right option for the job.
Custom options
