Abstract
A novel cutting method and apparatus includes a cutting blade adapted to consistently and easily form a desirable kerf in a concrete substrate while capturing substantially all resulting concrete dust.
Claims10
A circular saw apparatus comprising:
- a chassis member having an upper surface region, a forward edge and a rearward edge;
- a vacuum manifold mechanically coupled to said chassis member, said vacuum manifold including a blade box portion, said blade box portion having an edge region, said edge region defining a blade slot;
- a circular saw housing mechanically coupled to said chassis member, said circular saw housing containing an electric motor, said electric motor being operatively coupled to a circular saw blade, said circular saw blade having a saw blade surface region, said saw blade surface region being disposed substantially perpendicular to said upper surface region, a portion of said circular saw blade being disposed within said blade slot;
- a plurality of wheels respectively coupled to said chassis member, said wheels of said plurality each having a respective axis of rotation, at least one wheel of said plurality of wheels being disposed in proximity to said rearward edge;
- and
- a hose coupling tube having a first end, a second end, and a longitudinal axis that is substantially linear between said first and second ends, said hose coupling tube being coupled to said vacuum manifold at said first end such that said second end is disposed rearwardly of said one wheel and is adapted to be coupled to a vacuum hose.

A circular saw apparatus comprising:
- a mobile circular saw, said mobile circular saw being adapted to cut a generally planar substrate, said mobile circular saw including a generally circular blade;
- said mobile circular saw having a front end and a rear end, wherein said mobile circular saw is adapted to be moved relative to said generally planar substrate in a direction from said rear end towards said front end during a cutting operation;
- said circular saw including a substantially rigid hose coupling tube, said hose coupling tube including an intake end and an output end;
- said intake end being disposed in proximity to a cutting interface between said generally circular blade and said generally planar substrate;
- said output end being disposed relatively proximate to said rear end, said output end being adapted to be coupled to a vacuum hose.
