| 20110206472 | DRILLING TOOL AND METHOD FOR PRODUCING PORT SEALS - The present invention provides a new drilling tool useful in machining hydraulic port seals for fluid power ports. The drilling tool drills the port hole to size in a solid material for the minor thread diameter in combination with forming the port in a single operation. The drilling tool has a tool holder having a rotational axis, a first drilling insert having cutting surfaces on a first side and a mounting surface on a second side, at least one second drilling insert having a predetermined cutting surface portion and a mounting portion which is mounted on the holder at a location from the rotational axis of the holder. The at least one second drilling insert has first and second portions which engage and machine a work piece in a drilling operation to form a spot face and a seal form. | 08-25-2011 |
| 20100209203 | DRILL SYSTEMS, DRILL INSERTS AND METHODS - A drill system and cutting insert geometry is provided, with the system comprising a drill body having at least one cutting insert, with the at least one cutting insert is formed with at least one cutting edge, and has a first negative clearance surface and a second positive clearance surface, wherein the first negative clearance surface plastically deforms the surface of a work piece to produce a smooth surface finish and substantially reduce or eliminate chatter during a machining process. | 08-19-2010 |
