Tool Attachment for Raking Mortar Joints

A system comprising:

• a power tool with an operating element;
• a hollow shaft configured to surround the operating element;
• a substantially flat sled, wherein a bottom surface of the sled is configured to interface with a working surface;
• and
• a guidance fin protruding perpendicularly from the bottom surface of the sled, wherein the guidance fin is configured to guide the apparatus along an operating path.

An apparatus configured to be rotatably mounted to a power tool, the apparatus comprising:

• a hollow shaft configured to surround an operating element of the power tool, a front aspect of a distal end of the hollow shaft having a cutout;
• a substantially flat sled oriented at an acute angle relative to the hollow shaft, wherein a front aspect of the sled is bifurcated and a bottom surface of the sled is configured to interface with a working surface;
• a guidance fin protruding substantially perpendicularly from the bottom surface of the sled and having a width that is less than a width of the operating element of the power tool, the guidance fin configured to fit inside a mortar joint and guide the apparatus along an operating path;
• at least one vacuum port attachment built into a support member of the apparatus;
• and
• a split collar clamp configured to interface with a chuck of the power tool, the clamp having a cam-operated tightening mechanism and at least one locator feature for locating at least one predetermined position of the apparatus;
• wherein the apparatus is configured to rotate relative to the power tool about a longitudinal axis of the hollow shaft.
