| 20110293382 | TOOL ASSEMBLY AND TOOL HOLDER THEREFOR HAVING AN ELASTIC MEMBER - A multi-grooving tool holder for holding cutting members seated in a side-by-side formation in a clamping portion of the holder. The clamping portion includes an upper clamp and a lower clamp and an elastic member is located in one of the upper and lower clamps. When cutting members are assembled in the clamping portion, the elastic member engages the cutting members and aligns each cutting member independently, by applying a force, and consequently a moment on the cutting members. | 12-01-2011 |
| 20130129435 | EXCHANGEABLE INSERT SEAT MEMBER FOR CUTTING TOOL - The present invention relates to an exchangeable insert seat member for a metal cutting tool comprising a tool body and a cutting insert, wherein the exchangeable insert seat member is arranged to be placed between the tool body and the cutting insert wherein said exchangeable insert seat member is contacting said tool body and said cutting insert at contact areas arranged such that there is no direct contact between the tool body and the cutting insert and wherein said exchangeable insert seat member is produced by powder injection molding. The present invention also relates to a metal cutting tool comprising such an exchangeable insert seat member. | 05-23-2013 |
| 20130142578 | CUTTING INSERT AND ROTARY CUTTING TOOL - A cutting insert includes a first end surface, a second end surface located opposite the first end surface and an axis extending so as to penetrate the first end surface and the second end surface. The insert includes two first cutting edges with a curve shape on a first end surface side and two second cutting edges with a curve shape on a second end surface side. Each of the first cutting edges is formed on an intersecting ridge portion between the first end surface and a corresponding side surface portion so as to curve on a plane orthogonal to the axis. Each of the second cutting edges is formed on an intersecting ridge portion between the second end surface and the corresponding side surface portion so as to curve on a plane orthogonal to the axis. | 06-06-2013 |
| 20140072379 | CUTTING INSERT WITH FLEXIBILITY APERTURE AND CUTTING TOOL THEREFOR - An indexable cutting insert has mutually perpendicular longitudinal, lateral and vertical axes. The insert includes two opposite cutting portions and a clamping portion therebetween, arranged parallel to the longitudinal axis. Each cutting portion includes a rake surface and front and side relief flanks, and a cutting edge formed at an intersection of the rake surface and front relief flank. A second width of the clamping portion is greater than the first width of the cutting edges. The clamping portion has two resilient beams and a flexibility aperture opening out to side abutment surfaces of the clamping portion, allowing elastic deformation of the insert along the vertical axis. The cutting insert may further include two opposite stopper portions, each formed on a respective insert end surfaces, each stopper portion forming a step in the respective insert end surface. A cutting tool clamps one or more inserts at their clamping portions. | 03-13-2014 |
| 20160114399 | CUTTING INSERT FOR THREADING, TOOL BODY AND CUTTING TOOL - A cutting insert for threading of the present invention includes two opposing end surfaces and a peripheral side surface extending therebetween. The peripheral side surface has a first side surface portion and a second side surface portion arranged at different positions in a circumferential direction. A cutting edge is formed at an intersecting ridgeline portion between the first end surface and the first side surface portion and at least a portion of this cutting edge has a shape corresponding to a thread groove. The second side surface portion has an inclined portion which enlarges outward from the side of the first end surface toward the side of the second end surface. This inclined portion is configured to engage with a side wall surface of a tool body so as to prevent floating of the cutting insert. | 04-28-2016 |

| 20090324348 | CUTTING ELEMENT APPARATUSES, DRILL BITS INCLUDING SAME, METHODS OF CUTTING, AND METHODS OF ROTATING A CUTTING ELEMENT - A rotary drill bit for drilling a subterranean formation may comprise a bit body, a cutting element coupled to the bit body, and a torque-generating assembly configured to apply torque, either continuously or periodically, to the cutting element. The torque-generating assembly may be powered by the rotary motion of the rotary drill bit or may be hydraulically or electrically powered. The cutting element may comprise a substrate, a table of superabrasive material disposed on an end of the substrate, and at least one impelling feature formed along the exterior surface of the substrate. In addition, a method of rotating a cutting element coupled to a drill bit for drilling a subterranean formation may comprise providing a cutting element comprising a table bonded to a substrate, coupling the substrate of the cutting element to a drill bit body, and applying torque to the substrate of the cutting element. | 12-31-2009 |
