Additional Details

The Dremel 7122 has a shank size of 1/8 inch (3.2 mm), which is a standard size for Dremel rotary tools. It is important to use the appropriate speed setting on the rotary tool for the material being worked on and to wear eye protection during use. The grinding stone is typically pink or gray in color. It is best used with light pressure and multiple passes rather than heavy pressure in a single pass to prevent overheating and damage to the tool or workpiece.
