Twist Drill Bit is a tool for machining holes from solid materials, and it is also the most widely used tool in hole machining tools. The Easy Twist Drill Bit Tool is a tool for drilling the round hole of the workpiece through its rotary cutting relative to the fixed axis. It is named because its chip holding groove is in spiral shape and looks like fried dough twists. Spiral grooves have 2, 3, or more grooves, but 2 grooves are the most common. The High Speed Steel Twist Drill Bits can be clamped on the manual and electric hand fried dough twists drilling tools or drilling machines, milling machines, lathes and even machining centers. The Precision Twist Drill Bits are generally made of high-speed Tool steel or hard alloy. At present, precision twist drill bits are widely used in automobile manufacturing, logistics, mold, machinery and other departments. Because of its increasingly wide application in various fields, the requirements for application are also increasing.
The high speed steel twist drill bits are tools for drilling the round hole of the workpiece through their rotary cutting relative to the fixed axis. It is named because its chip holding groove is helical and shaped like Fried Dough Twists. The main cutting edge of the end mill is on the cylindrical surface, and the cutting edge on the end face is the auxiliary cutting edge. An end mill without a central edge cannot move along the axial direction of the milling cutter during operation. According to national standards, the diameter of the end milling cutter is 2-50 millimeters and can be divided into two types: coarse teeth and fine teeth. A diameter of 2-20 represents the range of straight shanks, and a diameter of 14-50 represents the range of conical shanks. The end mill is the Swiss Army knife among the CNC milling cutters. These multifunctional cutting tools can machine holes, grooves, and contours on workpieces with different grooves and tool tips. They come in various types, such as round end mills, rough end mills, V-shaped drill end mills, and flat end mills. The horizontal cutting edge on the side of the end milling cutter is called the chip removal groove, and its quantity affects the feed rate and cutting speed. When selecting an end milling cutter, it is necessary to consider the workpiece material, machining operation, and tool geometry. By using the correct end milling cutter, you can achieve a perfect balance between performance and accuracy, ensuring the success of your project.
