Ground set saw blade
A saw blade comprises a blade backer with a pair of side surfaces that extend substantially parallel to each other. An intermediate surface extends between the pair of side surfaces of the blade backer. A plurality of teeth extends from the intermediate surface. At least one of the teeth is located entirely within planes containing the side surfaces of the blade backer. A tip is formed at an apex end portion of the one tooth. A leading face surface of the tip on the one tooth is disposed at an acute angle relative to a plane extending perpendicular to the planes containing the side surfaces of the blade backer.
1. A saw comprising:
a blade backer having a pair of side surfaces extending substantially parallel to each other;
an intermediate surface of the blade backer extends between the pair of side surfaces of the blade backer;
a plurality of teeth extends from the intermediate surface, at least one tooth of the plurality of teeth has a portion located entirely within planes extending coplanar with the side surfaces of the blade backer;
a tip formed at an apex end portion of the one tooth; and
an entire leading face cutting surface of the tip on the one tooth being disposed at an acute angle relative to a plane extending perpendicular to the intermediate surface of the blade backer, a first side end of the leading face cutting surface extending outwardly from one of the planes that extend coplanar with the side surfaces of the blade backer a first distance taken at a height, a second side end of the leading face cutting surface extending outwardly from the other one of the planes that extend coplanar with the side surfaces of the blade backer a second distance different than the first distance taken at the height.
2. The saw of claim 1 wherein the intermediate surface extends in a direction perpendicular to the side surfaces and further including a top surface of the tip on the one tooth disposed at an acute angle relative to the intermediate surface of the blade backer.
3. The saw of claim 1 wherein the tip is welded to the one tooth and the tip is made from a material selected from the group comprising carbide, bi-metal, cermet, ceramic and diamond.
4. The saw of claim 1 wherein at least one surface of the tip is ground.
5. The saw of claim 1 wherein each of the plurality of teeth has a tip formed at an apex portion, each tip having laterally opposite end portions, at least one of the end portions of each tip extending outwardly beyond one of the planes extending coplanar with the side surfaces of the blade backer.
6. The saw of claim 1 wherein the first distance is at least twice the second distance.
7. The saw of claim 1 wherein the first side end is parallel to one of the planes that extend coplanar with the side surfaces of the blade backer and the second side end is parallel to the other one of the planes that extend coplanar with the side surfaces of the blade backer.
8. A tooth configuration for a cutting implement that has a backer with a pair of side surfaces extending substantially parallel to each other and an intermediate surface extending between the pair of side surfaces of the backer, the tooth configuration comprising:
a tooth extending from the intermediate surface, a portion of the tooth being located entirely within planes extending coplanar with the side surfaces of the backer;
a tip formed at an apex end portion of the tooth; and
an entire leading face cutting surface of the tip being disposed at an acute angle relative to a plane extending perpendicular to the intermediate surface of the backer, a first side end of the leading face cutting surface extending outwardly from one of the planes that extend coplanar with the side surfaces of the blade backer a first distance taken at a height, a second side end of the leading face cutting surface extending outwardly from the other one of the planes that extend coplanar with the side surfaces of the blade backer a second distance different than the first distance taken at the height.
9. The tooth configuration of claim 8 wherein the intermediate surface extends in a direction perpendicular to the side surfaces and a top surface of the tip on the tooth is disposed at an acute angle relative to the intermediate surface of the backer.
10. The tooth configuration of claim 8 wherein the tip is attached to the tooth and the tip is made from a material selected from the group comprising carbide, bimetal, cermet, ceramic and diamond.
11. The tooth configuration of claim 8 wherein at least one surface of the tip is ground.
12. The tooth configuration of claim 8 wherein the first distance is at least twice the second distance.
13. The tooth configuration of claim 8 wherein the first side end is parallel to one of the planes that extend coplanar with the side surfaces of the blade backer and the second side end is parallel to the other one of the planes that extend coplanar with the side surfaces of the blade backer.
