A drill removal device is provided for use with a scratch generating tool having a stationary member and a scrap generating workpiece engaging member that is moveable with respect to the stationary member. The debris removal device includes a bracket having a stationary member receiving portion for coupling the bracket to the power tool stationary member. A vacuum receiving portion of the bracket is provided for coupling the bracket to a vacuum source, and a passageway portion is provided for placing the stationary portion in fluid communication with the vacuum source. A variable tube bellows is configured for placement adjacent to the workpiece engaging member. The bellows includes a plurality of bi-stable pleats that are moveable between and stationarily positionable in each of an expanded position and a compressed position for permitting the user to vary the length of the bellows between, and fixedly positioned the length of the bellows at a plurality of different lengths.

The present invention relates to a machine tool which has the following: a machine bed 10 which is supported on machine feet 3, 3a and is formed from a supporting structure of ribs which are connected to one another, wherein two guide rails 1 are arranged on the top side, on opposite outer sides of the machine bed 10, and a machine table 2 is provided between the two guide rails 1, wherein first main ribs 11 are provided on either side of the machine bed 10, the profile of the said first main ribs, in cross section of the machine bed 10, beginning below the guide rails 1 and extending obliquely inwards in the machine bed 10 to external machine feet 3a in order to introduce loads, which act on the guide rails 1, into the machine feet 3, 3a.

The present disclosure relates generally to a tool that facilitates machining of inserts mounted in a primary component. More specifically, tools according to the present disclosure may be designed to support removal of recessed inserts in primary components without damaging the underlying primary components.

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).

An indexable plenum and a method of using the plenum to collect dust and/or debris during a cutting or milling process are disclosed. The plenum, when attached to the spindle nose of a conventional machine, enables the conventional machine that does not have a hollow spindle nose to be used with a hollow or conventional solid cutter to remove dust and/or debris generated during the cutting process. The indexable plenum comprises a hollow body and a base plate. Hollow bodies of different shape and size that are able to fit differently shaped and sized cutters are disclosed. The hollow bodies can be designed to releasably engage with the same base plate such that when the base plate is attached to the machine spindle nose, hollow bodies can be exchanged during a milling or cutting process to accommodate correspondingly shaped/sized cutters. In various embodiments, the object that is cut or milled is low density foam.

A hole cutter assembly is operable to cut a plurality of different sized diameter holes in a work piece. The hole cutter assembly includes an arbor configured to connect to a power tool for rotation about an axis, a drill bit coupled to the arbor for rotation with the arbor, a first arm moveable relative to the axis, a first cutting blade coupled to the first arm and moveable with the first arm, a second arm moveable relative to the axis, and a second cutting blade coupled to the second arm and moveable with the second arm. The first and second cutting blades are selectively moveable relative to the axis to adjust a cutting diameter of the hole cutter assembly. The drill bit engages the first and second arms to inhibit movement of the first and second cutting blades relative to the drill bit.

A hole cutter assembly is operable to cut a plurality of different sized diameter holes in a work piece. The hole cutter assembly includes an arbor configured to connect to a power tool for rotation about an axis, and a body coupled to the arbor for rotation with the arbor. The body defines an aperture. The hole cutter assembly includes a drill bit removably received in the aperture of the body for rotation with the arbor, an arm moveably coupled to the body, and a cutting blade coupled to the arm and moveable with the arm relative to the body. The arm is moveable relative to the body to adjust a cutting diameter of the hole cutter assembly when the drill bit is not received within the aperture. The arm is fixed relative to the body when the drill bit is received within the aperture.

An apparatus for collecting dust from a cutting unit is provided. The apparatus includes a rotary valve operatively connected to the cutting unit, a conduit in fluid communication with the rotary valve, and a compacting machine disposed downstream from the conduit and configured to receive dust from the conduit. A blower is configured to pull air downstream to carry the dust into the compacting machine. The compacting machine produces a compact from the dust.

A drilling byproduct recovery system employs a vacuum shroud positioned adjacent a workpiece. A spindle extends from a base and engages a tool. The spindle vertically reciprocates the tool upwardly through an aperture in the vacuum shroud to engage the workpiece. A circumferential air jet is emitted proximate a base of the spindle and directed toward the vacuum shroud.

An apparatus for the collection, gathering, and disposal of the debris that is created when drilling a hole into a vertical surface. The Disposable Drill Debris Eliminator (DDDE) is designed and constructed in a very simple manner and is thus very inexpensive to manufacturer; the DDDE is designed and constructed so that it is foldable, stackable, and thus very compact; the DDDE it is disposable; the DDDE contains in its design, a method of alignment, which enables the user to align the drill more easily to the intended hole position in a more perpendicular manner; the DDDE contains in it's design and construction, a device that enables the user to control the depth of the hole being drilled; and the DDDE is re-positionable for many uses because the adhesive strength is of the strength of re-positionable sticker notes.
