What does twist bit mean?

Twist bit is a type of drill bit that has a twisted flute design. This design helps to clear chips and debris from the hole being drilled, which makes it ideal for drilling in metal and other hard materials. Twist bits are also known as high-speed steel (HSS) bits because they are made from a type of steel that can withstand the high temperatures generated by drilling.

Twist bits come in a variety of sizes and shapes. The most common type of twist bit is the straight flute twist bit, which has a straight flute that runs from the tip of the bit to the shank. Other types of twist bits include the spiral flute twist bit, which has a spiral flute that helps to clear chips and debris even more effectively, and the parabolic flute twist bit, which has a parabolic flute that helps to reduce vibration and noise.

Twist bits are one of the most versatile and widely used types of drill bits. They can be used for a variety of drilling applications, including drilling in metal, wood, plastic, and other materials.
