This is a Dremel - actually a Mastercraft branded rotating tool (unsure what the generic name is). It is variable speed and comes with dozens of cutting, grinding, and sanding, accessories in a separate case. Please exercise caution with this tool. ALWAYS wear protective eye-ware and be extremely cautious at higher speeds since not all accessories are designed for that. Some may fly apart, and grinding wheels can shatter with explosive force. Please be careful and ensure you read up on and are comfortable with this tool before using.

A useful tool for detail work and shaping.
