Publication number: 20180221967Abstract: There is provided a drilling assembly and drill insert for producing holes in metal workpieces, wherein the drill insert body has a cutting end. The cutting end comprises at least two cutting lips formed transverse to each other. A web is formed between the two cutting lips, and each of the two cutting lips includes a cutting edge segment and at least one chip breaker. The chip breaker comprises at least one step in the cutting lip to produce a radial discontinuity in the cutting edge segment of the cutting lip for producing chips during machining which are of a width that is sufficiently reduced to allow proper evacuation from the hole produced thereby.Type: ApplicationFiled: February 6, 2018Publication date: August 9, 2018Inventors: Robert E. McKinley, Corey L. Lawrence, Joseph P. Nuzzi

Publication number: 20110206472Abstract: 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.Type: ApplicationFiled: May 5, 2011Publication date: August 25, 2011Applicant: ALLIED MACHINE & ENGINEERING CORP.Inventors: Joseph P. Nuzzi, Rolf H. Kraemer
