Fried Dough Twists drills are used to drill holes on hand drills, electric drills or machine tools. According to the shape of the clamping part, there are two types: straight handle and tapered handle. According to the function, there are two types: drilling and expanding. In addition, there are ladder Fried Dough Twists drills for drilling before tapping.

Fried Dough Twists drill is a kind of drill used for metal processing, usually made of high-speed steel or tungsten steel. High speed steel is an alloy steel with high strength, hardness, and wear resistance. It usually includes elements such as carbon, tungsten, molybdenum, chromium, cobalt, etc., and has good cutting and heat resistance properties.

In order to maintain good cutting performance and heat resistance, Fried Dough Twists drills usually need to have high hardness and strength. Therefore, commonly used Fried Dough Twists bits are made of high hardness alloy steels such as high-speed steel, tungsten steel, tungsten carbide, etc. These can meet the requirements of Fried Dough Twists bits in high-speed machining and high-temperature environments, and can improve the service life and processing efficiency of Fried Dough Twists bits.
