Types of high speed steel twist drills

As the most widely used twist drill bit, its raw materials are also an important factor that determines the quality of twist drills. High-speed steel and carbide are the two most common raw materials for twist drill bits. What I am talking about today is less than what everyone is talking about. What are the processing and drilling fields that high-speed steel twist drill bits are suitable for?

High-speed steel twist drills are suitable for many fields. According to materials, they can basically process copper, iron, aluminum, stainless steel, 45#, and other metal steels. When the hardness is within 30°, high-speed steel twist drills can basically be used. Can effectively complete stable drilling.

Because most of the current high-speed steel twist drills target holes with diameters generally within 50mm. If a straight-shank high-speed steel twist drill is used, the hole diameter that can be targeted is almost within 25mm, and generally no one in the market can make twist drills. Too complete, most high-speed steel twist drill bit manufacturers mainly use 0.3-13.0. The advantage of high-speed steel material itself is that it has good toughness. Whether it is machine drilling or manual drilling, it can produce the desired effect. Especially for some hole diameters that are not deep or shallow, ordinary alloy drill bits are used. Without toughness, chip removal is not good enough when processing medium-deep holes, and the tool is prone to breakage and chipping. However, the effect of using high-speed steel twist drills is the opposite. The wear resistance is not good enough in time. However, high-speed steel twist drills have the advantage of toughness and are widely used in various fields. All aspects can be stabilized, and if it is not wear-resistant, it can be used repeatedly through grinding. This situation is more cost-effective than using an alloy drill bit to directly break or chip. Therefore, when choosing hole processing tools, you must find a company you can trust when choosing high-speed steel twist drills.

First, let me tell you about the origin of the twist drill. The twist drill was invented, produced and promoted by an American machinist (Stephen A. Morse) in 1864. Because the shape of this drill bit resembles a twist, it is naturally called a twist drill in China. Drill. The invention and use of twist drills even provided a strong guarantee for the precise manufacturing and production of various weapons in World War I and World War II. A large number of German twist drill factories were also formed at the end of the 19th century and the beginning of the 20th century. Twist drills provided a powerful guarantee for the entire industrial revolution. It has also developed and made immortal contributions in modern times.
