Abstract

The present invention relates to a saw blade for cutting and finishing the surface of a work piece. The saw blade having a set of teeth disposed about the outer edge for making a cut in a work piece and an abrasive secured to the lateral surface of the saw blade. The abrasive extending laterally outwardly from the surface of the saw blade and providing a finishing effect on the work piece as the abrasive widens the cut beyond the cut of the saw blade teeth. A method for cutting and finishing a surface of a work piece utilizing a saw blade with an abrasive secured to a lateral surface of the blade and the abrasive extending beyond the cut of the saw blade teeth.

Claims

1. An apparatus for cutting and finishing the surface of a work piece and minimizing kickback, the apparatus comprising:

(a) a saw blade comprising two sides and teeth disposed along a first edge for producing a cut in a work piece and for finishing a surface on the work piece, the teeth having a tip at the outermost edge of the saw blade and a base disposed opposite the tip, the saw blade having a second edge disposed opposite the first edge;

(b) abrasive material embedded in both sides of the saw blade, the abrasive material disposed between a first boundary and a second boundary the first boundary disposed adjacent the base of the teeth, the second boundary disposed adjacent the second edge, the abrasive material extending laterally from both sides of the blade beyond the teeth;

(c) abrasive material disposed between the first and second boundary extending laterally from the first side beyond the teeth thereby creating a cut in the work piece wider than the teeth and preventing binding of the saw blade as the blade progresses through the work piece; and

(d) the saw blade comprising a blade selected from the group consisting of a circular saw, a reciprocating saw and a band saw.

2. A method for cutting and finishing a surface of a work piece in a single pass with a saw blade, said method comprising the steps of:

(a) selecting a saw blade with a first side and a second side and teeth for cutting the work piece, each tooth comprising a tip at the first edge of the saw blade and a tooth base disposed opposite the tip, the saw blade further comprising a second edge, the second edge disposed opposite the first edge;

(b) applying an abrasive material to both sides of the saw blade, the abrasive material having a first boundary and a second boundary, the first boundary disposed adjacent the base of the teeth, the second boundary disposed proximate the second edge, the abrasive material disposed between the first and second boundary extending laterally beyond the furthest extreme of the saw blade teeth;

(c) wherein the step of applying the abrasive material to the saw blade is by a process selected from the group consisting of adhering the abrasive material and embedding the abrasive material in the saw blade;

(d) passing the saw blade through the work piece to thereby simultaneously cut and finish the work piece surface; and

(e) forming a cut in the work piece wider than the teeth of the saw blade to prevent saw blade kickback.

3. The method as set forth in claim 2 wherein the step of selecting a saw blade comprises selecting a blade from the group consisting of a circular saw blade, a reciprocating saw blade and a band saw blade.

4. An apparatus for cutting and finishing the surface of a work piece, said apparatus comprising:

a saw blade with a first and second side and teeth for cutting the work piece, the teeth having a tip at the outermost edge of the saw blade and a base disposed opposite the tip, the saw blade having a first edge and a second edge, the base forming the first edge and the second edge disposed opposite the first edge;

an abrasive material embedded in at least the first side of the saw blade, the abrasive material extending laterally beyond the teeth between a first boundary and a second boundary, the first boundary coincident with the first edge, the second boundary proximate the second edge; and

means for securing the abrasive material by either embedding or bonding the abrasive material between the first boundary and the secondary boundary.
