What is an Air Die Grinder?
An air die grinder is a handheld power tool used for grinding, polishing, honing, sanding, and other intricate tasks. They are powered by compressed air, a motor that drives its rotary bit or abrasive accessory attached to its collet. Collets vary in size, typically ranging from 1/8-inch to 1/4-inch, allowing for a wide selection of accessories to choose from. Air die grinders are known for their precision, power, and ability to maneuver in tight spaces. They are flexible, versatile, and can handle various materials, including metal, plastic, wood, and more.
