Abstract
A method for cutting a chamfer on an edge of a concrete slab, the method comprising the steps of: making a generally planar cut, beginning a distance from the edge, with a generally circular, generally laminar concrete saw blade rotatably powered by a right-angle grinder motor, the generally planar cut being made at a desired angle and creating a cantilevered ledge above the generally planar cut; fracturing and removing at least a portion of the cantilevered ledge from the slab whenever an edge of the cantilevered ledge is proximate the hub; and continuing the generally planar cut until the cantilevered ledge is severed from the slab.

A method for cutting a chamfer on an edge of a concrete slab, the method comprising the steps of:
- making a generally planar cut, beginning a distance from the edge, with a generally circular, generally laminar concrete saw blade rotatably powered by a right-angle grinder motor, the generally planar cut being made at a desired angle and creating a cantilevered ledge above the generally planar cut;
- striking the cantilevered ledge with a tool in order to fracture and remove at least a portion of the cantilevered ledge from the slab whenever an edge of the cantilevered ledge is proximate the hub;
- and
- continuing the generally planar cut until the cantilevered ledge is severed from the slab.
A method for cutting a chamfer along an upper abutting edge of a first of two abutting concrete slabs, the abutting edge of the first concrete slab being elevated above an upper surface of the second concrete slab, the method comprising the steps of:
- making a generally planar cut, beginning a distance from the upper edge of the first concrete slab, with a generally circular, generally laminar concrete saw blade rotatably powered by a right-angle grinder motor, the generally planar cut being made at a desired angle selected so that a projection of a bottom surface of the planar cut intersects an upper abutting edge of the second concrete slab, the generally planar cut creating a cantilevered ledge above the planar cut;
- striking the cantilevered ledge with a tool in order to fracture and remove at least a portion of the cantilevered ledge from the slab whenever an edge of the cantilevered ledge is proximate the hub;
- and
- continuing the generally planar cut until the cantilevered ledge is severed from the slab.
