Abstract
A cutting or grinding tool includes a blade. The blade includes a disc-shaped base metal, cutting or grinding tips (edges) provided on a peak (outer circumferential edge) of the base metal, and a protruding coating on a side face of the base metal along the entire outer circumference of the base metal.
Claims14
A blade comprising:
- a disc-shaped base metal;
- cutting or grinding edges provided on an outer circumferential edge of the base metal;
- and
- a protruding coating on a side face of the base metal along at least 75% of the outer circumference of the base metal,
- wherein the protruding coating includes:
- a plurality of first coating elements arranged in a circumferential or radial direction of the base metal at predetermined intervals;
- and
- a plurality of second coating elements, where each second coating element is of different width from the width of each of the first coating elements, where the plurality of second coating elements are spaced apart at predetermined intervals to collectively form a plurality of V-shapes.

A blade comprising:
- a disc-shaped base metal with a circular hole at the radial center of the disc, the circular hole being extending in the direction perpendicular to the radial plane of the blade;
- cutting or grinding edges provided as tips on an outer circumferential edge of the base metal;
- and
- a protruding coating on at least one side face of the base metal along at least 75% of the outer circumference of the base metal parallel to the radial plane of the blade;
- wherein the protruding coating comprises two layers of coating elements including a first layer comprising coating elements comprising first linear lines radially spaced apart at equidistant intervals convering substantially the entire outer circumference.

A blade comprising:
- a disc-shaped base metal with a circular hole at the radial center of the disc, the circular hole being extending in the direction perpendicular to the radial plane of the blade;
- cutting or grinding edges provided as tips on an outer circumferential edge of the base metal;
- a protruding coating on at least one side face of the base metal along at least 75% of the outer circumference of the base metal parallel to the radial plane of the blade,
- wherein the protruding coating comprises a first layer of coating elements and a second layer of coating elements,
- wherein the first layer of coating elements comprises a C-shaped strip-like flat surface coating element surrounding and proximate to the radial center of the blade, and
- wherein the first layer coating element is spaced a predetermined radial distance from the radial center and extends radially up to proximately where the second layer of coating elements are formed.

A blade comprising:
- a disc-shaped base metal with a circular hole at the radial center of the disc, the circular hole being extending in the direction perpendicular to the radial plane of the blade;
- cutting or grinding edges provided as tips on an outer circumferential edge of the base metal;
- a protruding coating on at least one side face of the base metal along at least 75% of the outer circumference of the base metal parallel to the radial plane of the blade,
- wherein the protruding coating includes a plurality of coating elements spaced apart in the circumferential and radial directions of the base metal at predetermined intervals,
- wherien each of the coating elements is formed as a linear line, or a curved line in an arc shape, and
- wherein the coating elements are arranged at a predetermined angle with respect to a proximate virtual tangent line proximate to said coating elements being tangent to the outer circumferential edge of the base metal, approximately where a tip proximate to said coating elements is located.
