US 2008/0173293 A1 · TOOLS AND METHODS FOR MAKING AND USING TOOLS, BLADES AND METHODS OF MAKING AND USING BLADES, AND MACHINES FOR WORKING ON WORK PIECES

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.

Dependent claims

A saw with fluid regulation, wherein the saw comprises:

a housing;
a drive assembly supported by the housing;
a fluid supply supported relative to the housing;
a cutting assembly supported relative to the drive assembly, wherein the cutting assembly includes a support structure and at least one cutting element supported by the support structure for cutting a work piece, wherein a support structure includes at least one internal flow passage way for fluid and include communication with the fluid supply;
and
a changeable flow element between the fluid supply and the at least one internal flow passage way configured to change the flow fluid to the least one internal flow passage way in response to changes in a fluid flow characteristic.
