Fiber cement saw blade
The saw blade includes a plate supporting a plurality of teeth about the periphery thereof. Each tooth consists of a cutting tip supported in a tip pocket. The tips are brazed to the tip pockets with no side clearance taper created on the tips. The side faces on the tips are parallel to each other. The tip pockets are stamped into the blade using a high volume stamping process that employs a semi-circular relief at the proximate trailing corner of the tip pocket to receive the proximate trailing corner of the cutting tip. The relief can be formed in a high volume stamping process because it eliminates the need for a sharp corner. The relief accommodates the sharp edge of the cutting tip and allows the cutting tip to be properly seated on the tip pocket for connection thereto.
1 . A saw blade comprising:
a plurality of teeth disposed about the periphery of a blade having opposed parallel surfaces, each of said plurality of teeth including a cutting tip and a tip pocket;
said plurality of teeth including opposed side faces that are parallel to one another and parallel to the blade surfaces.
2 . The saw blade of claim 1 , wherein the tip pocket is formed of a back bottom face and a trailing face joined at a recess.
3 . The saw blade of claim 1 , wherein an edge of the cutting tips is located in the recess.
4 . The saw blade of claim 1 , wherein the cutting tip extends beyond the blade surfaces.
5 . The saw blade of claim 3 , wherein the cutting tips are brazed on the tip pockets.
6 . The saw blade of claim 1 , wherein the periphery of the saw blade has flat surfaces trailing the cutting tips.
7 . The saw blade of claim 6 , wherein the periphery of the blade other than the flat surfaces is circular.
8 . A method of making a saw blade tooth on a saw blade comprising:
stamping a plurality of tip pockets about the periphery of the blade;
providing a plurality of cutting tips, each of said plurality of cutting tips having opposed side faces that are parallel to one another;
securing one of the plurality of cutting tips on one of the plurality of tip pockets to complete the tooth.
9 . The method of claim 8 comprising:
stamping the tip pocket with a back bottom face and a trailing face joined and a recess joining the back bottom face and the trailing face.
10 . The saw blade of claim 9 , locating an edge of the cutting tip in the recess.
11 . A method of cutting fiber cement comprising:
providing a saw blade by stamping a plurality of tip pockets about the periphery of the blade;
providing a plurality of cutting tips, each of said plurality of cutting tips having opposed unground side faces that are parallel to one another;
securing one of the plurality of cutting tips on one of the plurality of tip pockets; and
cutting the material with the unground cutting tips.
