20140150622 | ROTARY BEVELMENT COMPOSITE SAW BLADE - A rotary bevelment composite saw blade comprises an outside saw blade and an inside saw blade. The outside saw blade and the inside saw blade rotate around a coaxial center of rotation, the outside saw blade and the inside saw blade rotate in opposite directions, and the outside saw blade and the inside saw blade are arranged in parallel. A bearing is arranged between the outside saw blade and the inside saw blade. An inner race of the hearing positions the outside saw blade, and an outer race of the bearing positions the inside saw blade. The outside saw blade and the inside saw blade freely rotate along with the inner race and the outer race of the bearing, respectively. Friction, interference, and collision are not generated between saw blades of the rotary bevelment composite saw blade, and the rotary bevelment composite saw blade is efficient, stable, and reliable in a cutting process, and is suitable to cut materials such as metal, stone, wood, and glass. | 06-05-2014 |

20090158910 | SAW TOOTH - A replaceable cutter tooth for mounting to a saw blade has a concave front cutting surface extending from and between opposite kerf forming linear side edges, and from and between a radially inner curved edge, radially inner when mounted on a saw blade, and a radially outermost curved cutting edge. A groove extends in the radial direction from the radially inner curved edge to the radially outermost curved edge, generally medially between and substantially parallel to the side edges so as to reduce the surface area of a front face of the front cutting surface of the tooth for ease of re-sharpening in the field | 06-25-2009 |
20100011934 | SAW TOOTH FOR CIRCULAR SAW - A tooth is provided for a circular disc felling saw. When installed on a saw blade, the tooth has both leading and trailing cutting tips that cut the tree. The cutting discharge of the trailing cutting tips may tend to wear the rearward flank of the leading cutting tips. Either one or both of the primary and secondary cutting tips may include a wear insert, such as a ceramic wear insert. | 01-21-2010 |
20130199353 | SAW TOOTH FOR CIRCULAR SAW - A tooth is provided for a circular disc felling saw. When installed on a saw blade, the tooth has both leading and trailing cutting tips that cut the tree. The cutting discharge of the trailing cutting tips may tend to wear the rearward flank of the leading cutting tips. Either one or both of the primary and secondary cutting tips may include a wear insert, such as a ceramic wear insert. | 08-08-2013 |
083840000 | By independent connecting element | 6 |
20090031877 | SAW BLADE ASSEMBLY FOR A CUTTING SAW - A saw blade assembly for a cutting saw is provided, which includes an effectively circular polygonal disc with an outer edge defined by multiple flat sides, and numerous saw tooth holders, each saw tooth holder removably mounted on a corresponding flat side along the outer edge of the polygonal disc. Preferably, each saw tooth holder straddles the corresponding flat side of the polygonal disc. The saw tooth holder may have a body with a flat abutment surface abutting the corresponding flat side of the polygonal disc, a first leg extending from the body along a first surface of the polygonal disc, and a second leg extending from the body along a second surface of the polygonal disc. For each saw tooth holder, the saw blade assembly may also include fastening means removably mounting the saw tooth holder to the polygonal disc. | 02-05-2009 |
20100058917 | CUTTING TOOL WITH CUTTING INSERT HAVING MULTIPLE CUTTING EDGES, AND CUTTING INSERT THEREFOR - A cutting tool includes a cutting insert. The insert includes a top side including a plurality of cutting edges, the cutting edges being arranged one after another in a longitudinally direction of the insert and extending substantially perpendicularly to a longitudinal, vertical axial plane of the insert. The insert includes a side wall extending downwardly relative to a plane of the top side of the insert, the side wall including a side supporting surface. The cutting tool includes a toolholder. The toolholder includes a side abutment surface against which the side supporting surface of the insert is adapted to be supported. A clamp is provided for clamping the side supporting surface of the insert against the side abutment surface of the toolholder. | 03-11-2010 |
20100170378 | CUTTING TOOTH ASSEMBLY WITH REVERSIBLE TOOTH - A cutting tooth assembly for a rotary cutting machine is described. The assembly includes a tooth holder adapted for mounting about the periphery of a rotating element of the rotary cutting machine, and a reversible cutting tooth, removably mounted to said tooth holder. The cutting tooth has opposed first and second cutting faces which are spaced apart along a central tooth axis extending therebetween. Each of the first and second cutting faces at least partially defines more than two cutting edges, and the cutting tooth is reversible by 180 degrees about a transverse tooth axis to dispose a selected one of the first and second cutting faces in an operable cutting position when mounted to the tooth holder. | 07-08-2010 |
20100170379 | ROTARY CUTTING MACHINE WITH REVERSIBLE TEETH - A rotary cutting machine is described and includes a circular rotatable element, a plurality of tooth holders disposed on the circular rotatable element at spaced apart locations about its periphery, and at least one reversible cutting tooth removably fastened to each tooth holder such that at least one cutting edge is disposed in a operable cutting position. Each cutting tooth includes opposed first and second cutting faces spaced apart along a central tooth axis extending therebetween. Each of the first and second cutting faces at least partially defines at least four of the cutting edges. The cutting tooth is reversible by 180 degrees about a transverse tooth axis such that it is mountable on the tooth holder in at least eight different positions, each of the positions providing a different selected one of the cutting edges in the operable cutting position. | 07-08-2010 |
