Twist Drill And Drill Rod Gage

Twist Drill and Drill Rod Gage are two types of measuring tools used in the field of craftsmanship.

A Twist Drill is a cutting tool used to create holes in various materials such as wood, metal, or plastic. It consists of a cylindrical shank with spiral flutes that help to remove the material as the drill rotates. The size of a twist drill is typically measured in terms of its diameter, which can be determined using a drill rod gage.

A Drill Rod Gage, also known as a drill bit gauge or drill gauge, is a measuring tool specifically designed to measure the diameter of twist drills. It usually consists of a series of holes or slots with labeled sizes that correspond to the standard drill bit sizes. By inserting the twist drill into the appropriate hole or slot on the drill rod gage, craftsmen can quickly and accurately determine the size of the drill bit.

These measuring tools are essential for craftsmen who need to ensure precise hole sizes and select the appropriate drill bit for their projects.
