Abstract
A cutting tool attachment for a power tool is freely rotatable about an end of the power tool. A fence provides a complementary flat surface area for the cutting tool attachment to rest against a surface of the material to be cut. The fence prevents free rotation of the cutting tool attachment while in use. A handle allows a user to guide the attachment along the surface of the material, while also providing leverage to keep the attachment against the material surface close to the attachment, but at a safe position to reduce the chance of injury. A user can rotate the power tool relative to the cutting attachment to achieve a comfortable position or to help turn the attachment and power tool. The power tool is therefore positionable along a 360 arc of movement relative to the attachment while the attachment is positioned along the surface of a material.
