| 20110197736 | CIRCULAR SAW BLADE WITH CUTTING TIPS MECHANICALLY LOCKED AGAINST MULTIPLE FORCE VECTORS - A circular saw blade comprises a substantially planar main body having an essentially circular periphery in which are formed a plurality of annularly spaced tip support portions, and a plurality of cutting tips affixed by brazing to the tip support portions of the main body. Each cutting tip has a mounting base formed with at least two locking surfaces along which the brazing affixes the mounting base to a respective tip support portion. The locking surfaces are configured and located in relation to one another and to the main body for counteracting forces which act against the cutting tip in differing directions in the plane of the main body during rotational cutting operation of the blade. | 08-18-2011 |
| 20080307941 | Saw blade tooth geometry for circular saw blade - A circular saw blade includes a generally flat disk with a cutting periphery defined by a plurality of carbide teeth arranged in spaced relation around the perimeter of the disk and projecting radially outwardly from the disk. Each tooth of the cutting periphery includes a pair of spaced-apart primary side faces, a cutting face having a cutting edge with a top bevel angle within the range of at least 25 degrees to about 50 degrees, and at least two secondary side faces. Each secondary side face extends between the cutting face and a respective one of the pair of primary side faces and has a relief angle relative to the immediately adjoining primary side face. The circular saw blade of the present invention is ably suited to provide a smooth cutting finish without splintering of the top and bottom edges in connection with a wide variety of cuts, including crosscutting and ripcutting. | 12-18-2008 |
