Abstract

A saw comprises a saw blade having an outer edge, and a diamond-containing coating carried on the outer edge of the saw blade, the saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers with a volume fraction of 30-70%.

Claims

1. A saw, comprising a saw blade having an edge;

and a diamond-containing coating carried on said edge of said saw blade, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said fiber material being formed by a plurality of mats, said mats of said fiber material in said saw blade being arranged in a single layer.

2. A saw, comprising a saw blade having an edge;

and a diamond-containing coating carried on said edge of said saw blade, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said fiber material being formed by a plurality of mats, said mats being formed as circular segments, arranged in rotation-symmetrical manner relative to an axis of said saw blade.

3. A saw as defined in claim 2, wherein said mats have edge regions and overlap one another in said edge regions.

4. A saw, comprising a saw blade having an edge;

and a diamond-containing coating carried on said edge of said saw blade, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said coating having a carrier with a T-shaped cross-section, said carrier having a central web which is embedded in the synthetic plastic of said saw blade and provided with an anchoring formation for anchoring in the synthetic plastic of said saw blade, said anchoring formation being formed by a plurality of ribs.

5. A saw, comprising a saw blade having an edge;

and a diamond-containing coating carried on said edge of said saw blade, said saw blade being composed of a synthetic plastic reinforced with a fiber material composed of a plurality of fibers selected from the group consisting of carbon fibers and graphite fibers with a volume fraction of 30-70%, said coating having a carrier with a T-shaped cross-section, said carrier having a central web which is embedded in the synthetic plastic of said saw blade and provided with an anchoring formation for anchoring in the synthetic plastic of said saw blade, said anchoring formation being formed as a grain.
