Abstract
Cutting tools are provided that include a circular core with a cutting means located on its periphery, a central bore to receive an arbor of a rotating power tool and one or more perforations extending through the central core. The perforations are disposed along a circumference disposed concentrically with, and between, the central bore and the periphery. The perforations are arranged to form an annular window through the core which corresponds to a predetermined cutting depth during rotational operation of the tool.
Claims21
A cutting tool comprising:
- a core having a cutting periphery;
- a central bore configured to receive a drive mechanism of a rotating power tool;
- a plurality of perforations extending through said core, said perforations being bounded in 360 degrees by said core;
- said perforations defining a notional, annular window through said core during rotational operation of said blade;
- said window corresponding to a predetermined depth of cut.
A method of fabricating a saw blade having an integral depth gauge, the method comprising:
- (a) providing a solid circular core having a plurality of cutters disposed along a periphery thereof;
- (b) providing the core with a central bore configured to receive an arbor of a rotating power tool;
- (c) extending a plurality of perforations through the core, wherein the perforations are bounded in 360 degrees by the core;
- and
- (d) spacing the perforations along at least one circumference disposed concentrically with, and between, the central bore and the periphery;
- wherein the perforations define a notional, annular window through the core during rotational operation of said blade, which window forms an integral depth gauge corresponding to a predetermined depth of cut.
A saw blade with integral depth gauge, the saw blade comprising:
- a circular core having a plurality of cutting means disposed along a periphery thereof;
- bore means for retaining the blade on an arbor of a rotating power tool;
- perforation means extending through said core, said perforation means being bounded in 360 degrees by said core;
- said perforation means being spaced along at least one circumference disposed concentrically with, and between, the central bore means and the periphery;
- said perforation means defining a notional, annular window through said core during rotational operation of said blade;
- wherein said window forms an integral depth gauge corresponding to a predetermined depth of cut.
