In order to ensure that the drill bit is strong and durable, vacuum secondary tempering and heat treatment steps are added to the CNC precision production process. This increases its durability, making it a reliable choice for both professional and self-service tasks. The screwdriver head is made of high-quality chromium vanadium steel, which has good toughness, wear resistance and corrosion resistance. These qualities make it an excellent choice for mechanical applications. To ensure optimal performance and longevity, the screwdriver bits are electroplated in addition to the traditional HSS design. It is a sturdy option that can withstand the weather and the environment as it is coated with black phosphate to prevent corrosion.By using the precision-built drill bit, there is a tighter fit and less CAM stripping, resulting in higher drilling accuracy and efficiency as well. In addition to the sturdy box that encloses each tool for safe and secure storage, there is also a convenient storage box included with each tool. It is important that each piece of equipment is positioned exactly where it should be during shipment. It is also important to note that simple storage options will help you find the right accessories more easily, saving you time.
