Dust abatement for a concrete cutting tool

A concrete cutting system, comprising:

• a concrete cutting tool;
• a saw blade secured by bolts to a hub secured to a spindle of the concrete cutting tool;
• and
• a dust abatement device including:
• a frame including:
• a front guard in front of the spindle and over the saw blade;
• and
• a rear guard behind the spindle and over the saw blade;
• a dust collector adjacent to the frame and including an inlet, a conduit, and an outlet;
• and
• a pliable skirt over the frame and the inlet of the dust collector, the pliable skirt being arcuate in shape, oriented substantially horizontally, having sufficient flexibility to enable a portion of the pliable skirt to lay flat against a concrete surface, and having sufficient rigidity to define a channel extending arcuately in front of the front guard to the inlet of the dust collector, a portion of the saw blade extending into the channel.

A method for cutting concrete, comprising:

• assembling a dust abatement device with a concrete cutting tool;
• cutting a substrate with a saw blade coupled to a hub coupled to a spindle of the concrete cutting tool;
• shielding dust generated while cutting the substrate from turbulence generated by the spindle and/or the hub with a pliable skirt that is arcuate in shape, oriented substantially horizontally, and has sufficient flexibility to enable a periphery of the pliable skirt to lay flat against a surface of the substrate;
• transporting the dust through a channel defined by an upwardly tapered portion of the pliable skirt as the periphery of the pliable skirt lays flat against the surface of the substrate, the channel extending arcuately and receiving at least a portion of the saw blade.
