Twist Drill by Hangzhou Fanxi Tools Co., Ltd.

The Twist Drill by Hangzhou Fanxi Tools Co., Ltd. is the most common type of drill preferred by both the DIY enthusiasts and industrial professionals. It is designed to meet the diverse drilling needs of various applications.

The drill features a straight or tapered shank that is securely held by the machine tool, providing a reliable rotary motion for efficient drilling. Its body consists of two spiral grooves known as flutes, which are defined by a helix angle of approximately 30 degrees, although this angle may vary depending on the material properties of the workpiece.

The point of the drill forms a 118-degree angle, ensuring precise and accurate drilling. It includes a 10-degree clearance angle and a chisel edge with a web thickness of approximately 0.015 times the drill diameter. While the chisel edge can sometimes cause problems in hole location by "walking" on a surface, it is a versatile feature that enhances the drill's performance.

For brittle materials, the drill point angles of less than 118 degrees are recommended, while ductile materials require larger point angles and smaller clearance angles.

The Twist Drill is ideal for both portable and machine drilling. It is specifically designed to perform exceptionally well in low and medium carbon steel, cast iron, and wood. Its 135-degree split point is self-centering, reducing thrust and ensuring accurate drilling. This makes it perfect for low tensile strength alloy materials, stainless steel, and other medium-duty applications.

The Twist Drill is available in various finishes, including bright finish, black oxide, titanium nitride coated, and bronze color oxide. This wide range of choices allows consumers to select the most suitable option for their specific needs.

Choose the Twist Drill by Hangzhou Fanxi Tools Co., Ltd. for reliable, efficient, and precise drilling in a variety of materials and applications.
