DIN345 taper shank twist drill is a common drill bit that is manufactured in two different ways: milled and rolled.
Milled DIN345 taper shank twist drills are manufactured using a CNC milling machine or other milling process. This manufacturing method uses a tool to mill the surface of the drill bit to form a twist-shaped cutting edge. Milled drill bits have good cutting performance and cutting efficiency and are suitable for drilling needs in various materials.
One of the main advantages of HSS taper shank drill bits is their excellent hardness and heat resistance. High-speed steel is a tool steel that is specially formulated to withstand high temperatures and maintain its cutting edge even at high speeds. This makes HSS taper shank drill bits ideal for heavy-duty drilling operations that require high cutting speeds and feed rates. In addition, the hardness of HSS enables these drill bits to maintain sharpness and cutting performance after long-term use.
Rolled DIN345 taper shank twist drills are manufactured using a rolling process. In this manufacturing method, the drill bit undergoes a special rolling process to form a twist shape on the cutting edge. Rolled drills have high strength and wear resistance and are suitable for drilling tasks in high-load and high-strength materials.
Whether milled or rolled DIN345 taper shank twist drills, they all meet the DIN345 standard, ensuring their quality and dimensional consistency. They are widely used in metal processing, machinery manufacturing, mold manufacturing and other fields, providing efficient, accurate and stable drilling capabilities.
The choice of milled or rolled DIN345 taper shank twist drills can be determined based on specific drilling needs, material properties and process requirements.
In addition to durability and extended range, HSS taper shank drills are also known for their precision and accuracy. The tapered shank design ensures a firm and concentric fit in the drill chuck, minimizing runout and vibration during the drilling process. This allows for cleaner, more precise, and tighter tolerance holes to be drilled, making HSS taper shank drills the first choice for applications that require high precision and high-quality surface finishes.
When choosing the right HSS taper shank drill for a specific application, it is important to consider factors such as the material being drilled, the required hole size, and the drilling equipment used. Different flute designs, point angles, and coatings are available to optimize performance for specific materials and cutting conditions. For example, a drill with a 118-degree point angle is ideal for general-purpose drilling in a variety of materials, while a drill with a 135-degree point angle is better suited for drilling harder materials, such as stainless steel and alloy steels.
In summary, the HSS taper drill bit is a versatile and reliable tool that provides excellent durability, precision, and performance in a variety of drilling applications. The extra-long design, combined with the superior hardness and heat resistance of high-speed steel, makes it ideal for heavy-duty drilling tasks that require a wide range and high cutting speeds. Whether drilling through tough metals or creating precise holes to tight tolerances, the HSS taper drill bit is a valuable asset for professionals in the construction, manufacturing, and metalworking industries.
