TWIST DRILL Meaning and
Definition
-
A twist drill is a type of rotary cutting tool used in drilling operations to create holes in various materials, including wood, metal, and plastic. It consists of a cylindrical shank, a helical flute, and a pointed cutting edge.
The shank is the non-cutting part of the drill that is held by the chuck of a drilling machine or power drill. It provides a means of rotating the twist drill, enabling the cutting action. The helical flute, which is the spiral groove around the shank, works as a channel for removing the chips or swarf generated during the drilling process. It also helps to guide and control the drill bit while it is in use.
The pointed cutting edge is the most crucial part of the twist drill, as it is responsible for creating the hole. It has a sharp tip, which is often ground to a specific angle or point geometry depending on the material being drilled. This cutting edge is designed to penetrate the workpiece and remove material in a rotating motion.
Twist drills are available in various sizes and designs to accommodate different drilling applications. They can have different flute lengths, diameters, and point angles, allowing for customization based on specific requirements. Overall, twist drills are versatile and widely used tools in industries, workshops, and households for creating holes of various sizes and depths in different materials.

Etymology of TWIST DRILL
The term "twist drill" has an etymology related to its design and function.
The word "drill" comes from the Old English word "drilian", which means "to bore" or "to pierce with a tool". This term has Germanic origins and is related to Old High German "trullan", meaning "to pierce".
The term "twist" refers to the spiral shape or helical fluting present on the drill's cutting edge. The spiral fluting of a twist drill helps to remove material as it rotates into the surface being drilled. The word "twist" originated from the Middle English word "twisten" meaning "to turn" or "to rotate".
Therefore, the term "twist drill" combines "twist" referencing the spiral shape and "drill" indicating its function of boring or piercing.
