ABSTRACT:
Methods and apparatus for making and using tools, for example concrete cutting blades, may use laminations. They may also include inserts, such as structural inserts, damping inserts and fluid flow elements. Fluid flow elements may include a tube, a transition element including an inlet fitting, a fluid pressure containment structure inserted into the channel of the blade, an added material resistant to effects of the fluid including plastics, coatings and films, and other structures. Additional nozzle structures may be included. Methods and apparatus for making and using tools including concrete cutting blades having improved damping characteristics may include inserts, plugs and other structures, including those made from materials softer or more ductile than the tool material. Methods and apparatus for making and using tools including concrete cutting blades having improved flow directing capabilities may include inserts or other structures having vanes, foil structures, fluid diverting surfaces, baffles or other structures for affecting fluid flow in the area of the tool.
