A deburring reamer device comprising a main body. The main body may comprise a first end and a second end. The first end may comprise a right-angle bend and a hole at a tip of the first end. The right angle bend may allow for pipes near studs or in hard-to-reach places to be reached by the device. The device may further comprise a rotation component disposed within the main body coupled to the hole. The device may further comprise a blade removably disposed in the hole of the main body. The blade may be configured to fit into the rotation component. The device may further comprise an actuator disposed on a surface of the main body, operatively coupled to the rotation component. Actuating the actuator may cause the rotation component to rotate the blade.

A repair device for underwater repair of a hole in a nuclear reactor part includes a holder (32), a cutting tool (22) held by the holder (32) and having at least one cutting tooth (70) for remachining an inner surface of the hole. The cutting tool (22) has a suction channel (44) extending into the cutting tool (22) between at least one inlet opening (46) and at least one outlet opening (48), a drive shaft (34) for rotating the cutting tool (22), the drive shaft (34) being held by the holder (32), and a suction tube (36) connected to the holder (32) and fluidly connected to the outlet opening (48) of the suction channel (44).

A cooling bore guide for reaming an enlarged portion into a cooling bore of a rotor. The cooling bore guide may include a cutter guide for insertion into the cooling bore and a guide lock for insertion into an adjacent cooling bore.

A drilling tool, in particular a reamer, for drilling out a workpiece core bore to a nominal diameter by means of a main blade formed on a drill body is disclosed. The main blade has a radially external cutting edge which extends along a drill-body longitudinal axis as far as a blade corner arranged at the drill tip, wherein during the drilling-out operation, the drilling tool is drivable into the workpiece core bore with a rotary movement and a feed movement. The drilling tool has at least one groove blade which is arranged so as to precede the blade corner of the main blade in the direction of rotation of the tool. During the drilling-out operation, the groove blade produces a groove in the inner wall of the core bore drilling, the blade corner of the main blade being guided in the groove with an at least reduced cutting load.

A bottom cutting step up reamer incorporates a shaft having a first end with attachment features adapted to be received in a chuck. A plurality of bottom cutting edges substantially perpendicular to the shaft are located at a second end distal from the first end. At least one step up land is provided proximate the plurality of bottom cutting edges and spaced toward the first end with a plurality of parallel cutting edges substantially parallel to the shaft.
