The screwdriver bit is a common consumable in decoration, and its price ranges from a few cents to dozens of yuan. Many screwdriver screwdriver bits are also sold with screwdrivers. Do you really understand the screwdriver bit? What do the letters “HRC” and “PH” on the screwdriver bit mean? Why are some screwdriver bits extremely durable?
The screwdriver bit is often subjected to greater impact and vibration during use, so a good screwdriver bit must take into account hardness, toughness and wear resistance. As users, we certainly expect the screwdriver bit to be able to screw more screws and have a longer service life, so as to achieve the purpose of improving production efficiency and reducing production costs. So how should we choose a screwdriver bit?
1. S2 tool steel has excellent performance
To judge whether the screwdriver bit is durable, first look at the material of the screwdriver bit. Before buying, you should choose according to your needs. At present, the following four materials are mainly used on the market, among which S2 tool steel has an HRC value of 58~62; it has the highest hardness and the strongest impact resistance, and is the leader among the raw materials of the screwdriver bit.
A good screwdriver screwdriver bit should be made of S2 material. The harder the screwdriver screwdriver bit, the more durable it is. Too high a hardness will cause the screwdriver bit to break, and too soft a hardness will cause the screwdriver bit to slip. The internationally recognized stable hardness is HRC60±. Eurocut tools use S2 tool steel, and the screwdriver heads that have been optimized through heat treatment have a hardness of up to 62 HRC. During the standard testing process in the Eurocut tool laboratory, the reliable and durable performance of the high-hardness impact-resistant screwdriver heads of Eurocut tools increased by 50%, and the torque increased by 3 times. In the multi-product confrontation experiment, the Eurocut screwdriver heads performed excellently with a ratio of 1 to 10.
2.The treatment process is very different
The quality of the screwdriver head depends not only on the material, but also on the heat treatment and surface treatment process.
The heat treatment process can maximize the torque and fatigue resistance of the steel and improve the quality of the screwdriver head. Eurocut Tools, a brand with decades of history, has rich experience in the production and manufacturing of hardware tools. The heat treatment process can better complete the three stages of raw material heating, heat preservation and cooling, and the quality of the screwdriver head is guaranteed!
The surface treatment process can not only increase the beauty and glossiness of the product, but also enhance the corrosion resistance of the product, thereby extending the service life of the screwdriver head.Common surface treatment processes include: sandblasting, reddening, oxidation (blackening), phosphating, electroplating, mirroring, polishing, etc.In addition to the above common surface treatment processes, the Eurocut tool’s screwdriver bit has also upgraded the sheath, which provides strong protection for the screwdriver bit, greatly enhances corrosion resistance, is not easy to rust, and has a longer service life.
3. Processing accuracy is very important
The same screw, tightened with different screwdriver bits, the tightening degree is completely different, because the precision of the screwdriver bits processed by different molds is different.
The Eurocut tool’s screwdriver bit has been precisely calibrated many times during the production process, and has high precision; when it is installed on an electric or pneumatic screwdriver bit and rotated, the deflection is small, and its head is certainly not easy to be damaged.
The requirements of the Eurocut tool for the process are not limited to this, nor are they limited to this. Some products have been newly upgraded to a toothed design, which makes the screwdriver bit and the screw screwdriver bite more tightly and not easy to slip. Reduce product wear and naturally extend service life.
In addition, the angle of the bevel cut of the Eurocut tool screwdriver bit is straight, which can directly transmit the force to the cross hole and is not easy to slip.
Eurocut tools strictly control the quality of the details of the screw screwdriver bits, such as the concentration correction process, which is also the guarantee of the durability of the Eurocut tool screw screwdriver bits. Long-term use can also reduce the probability of deviation and slip.
4. Hard collisions, more damage
Another important reason for many people’s screw screwdriver bits being damaged is that the selected screw screwdriver bits are not completely matched with the screws. The screw screwdriver bits can be divided into many models according to the head, such as flat head, cross, Pozi, star, plum blossom, hexagon, etc., among which flat head and cross are the most commonly used. The wrong screw screwdriver bit model is often the most direct culprit for screwing screws. The result of a “hard collision” is that the screw screwdriver bit is also damaged! Therefore, before screwing the screws, it is necessary to correctly identify the PH value and the size of the corresponding screws.
5. The intimate design is indispensable
Shock-absorbing design: the force point and the middle concave arc buffer belt rod share the force, reduce the original force strength of the top force head, play a buffering role, and increase the fatigue limit of the screwdriver rod, thereby increasing the service life of the screwdriver and saving users a lot of costs.
Strong magnetic design: Eurocut tool belt magnetic screwdriver bit has strong adsorption ability and can easily adsorb screws; magnetic rings can also be added, and the magnet material is doubled, which increases the adsorption capacity, says goodbye to screws slipping, and reduces product loss.
How to choose a good and cheap screwdriver bit is a science. Have you learned it through the introduction of Eurocut?
