![]() Suitable Cutting Materials:Carbon steel, alloy steel, stainless steel, cast iron, aluminum, copper. They can be used for drilling materials such as steel with a hardness below HRC30, stainless steel, cast iron, aluminum alloys, copper alloys, and more. They need to possess high hardness and sharpness to ensure product durability and are suitable for both rough and fine machining. Micro drill bits refer to those with a diameter smaller than 3mm. Suitable Cutting Materials:Steel, Hardened Steel, Cast Iron, Aluminum, Copper During high-speed cutting, the spiral flutes help facilitate the easy removal of metal chips. Its main purpose is to drill a small hole that can guide subsequent drilling processes. ![]() The center drill is commonly used to create different types of center holes, primarily 60°and 90°angles. Suitable for cutting materials: Carbon steel, low alloy steel, high alloy steel, hardened steel, cast iron. It incorporates a taper design to precisely locate the drilling position, ensuring that other functional drill bits can accurately find the center hole.ĭrill Bit Category:Solid Carbide Spot Drill Here's a detailed introduction to each type:Ī spot drill, also known as a center drill, is a pre-drilling tool used to prevent drilling deviation. Many people refer to twist drills as spiral drills, but in reality, any drill bit with a rotating cutting design for creating circular holes falls under this category. Some manufacturers also apply nanocoatings or incorporate center water outlets to enhance the cutting performance of the drill bits.Ĭommon types of drill bits include spot drills, center drills, micro-drills, high-speed drills, and flat head drills. ![]() Materials such as steel, hardened steel, stainless steel, cast iron, titanium alloy, nickel alloy, aluminum, copper, and plastics can be cut using specific drill bits. Different materials require different drill bits based on their rigidity and external design. There are various sizes, shapes, and types of drill bits available. After reading this, you will be able to choose the right drilling and cutting tool for your needs more efficiently!Ī drill bit is a cutting tool that operates by rotating to remove material and create holes. Today, we will share with you what a drill bit is and the various types available. Whether it's drilling holes in cement, metal, wood, tiles, or glass, drill bits are essential. It finds applications ranging from DIY home renovations to industrial production lines. A drill bit is a commonly used cutting tool component.
