Provided herein are surgical guides with internal channels for irrigation cooling. In one embodiment, an apparatus for guiding a surgical instrument includes a proximal side and a distal side. A first channel is configured to guide a material removal device, where the first channel extends from the proximal side of the apparatus to the distal side of the apparatus. A second channel configured to direct irrigation fluid, where the second channel extends from the proximal side of the of the apparatus to the distal side of the apparatus. The first channel is separate from the second channel. A method of performing a surgical procedure and a method of manufacturing a surgical guide are also disclosed. In certain embodiments, the surgical guides may be manufactured via additive manufacturing processes, including for example, three-dimensional printing processes.
