Abstract
Abstract A saw guide is provided with cooling and lubricating capability which guides a saw during cutting of wood and other materials and includes a mixing capability so that two coolants and/or lubricants can be mixed at the saw guide just prior to cooling or lubrication of a saw blade to reduce the likelihood of separation of insoluble combinations of coolants and/or lubricants prior to application to the saw blade.
