Abstract:
A pipe end chamfering tool for creating a bevel on the inside diameter or the outside diameter, or the inside and the outside diameter of a pipe end. The tool includes a body, one or more first projections, and at least one chamfering region at the juncture of the body and each first projection. The chamfering region is configured to cut either an inside bevel, or an outside bevel, or both an inside and an outside bevel on a pipe end. The first projection has a proximal, a middle and a terminal segment. The middle segment has a width essentially equal to the inside diameter of the pipe to be chamfered and stabilizes the pipe during chamfering. The terminal segment is semicircular and is oriented perpendicular to the plane of the proximal and middle segments. The terminal segment collects and allows removal of chips or shavings created on the inside of the pipe during chamfering. The tool includes a second projection oriented perpendicularly to the body and, in conjunction with the edge of the body opposite the second projection, provides a measuring device for an operator to mark the length of pipe which should be inserted into a stab-type pipe coupler to achieve an effective connection.
Abstract:
An improved slot-drilling cutter has a tool body with plate seats at the end, which are arranged symmetrically in respect to each other. Cutting plates are arranged on the seats, whose cutting edges, as well as possibly cutting edges 41, 42, are set identically, i.e. which cover each other completely in the circumferential direction. Because of this, respectively two cutting edges are active for the drilling operation, as well as for the milling operation, which increases the metal cutting yield and allows the same advancement when drilling, as well as when milling. The slot-drilling cutter is free of lateral forces because of the symmetrical design, which permits a high degree of working precision in spite of large advancement moves.
Abstract:
A tool for the fine machining of workpieces having at least one cutter tip and at least one setting device acting on the cutter tip. The setting device comprises an adjusting element extending over a region of one side face of the cutter tip. A set screw displaces the adjusting element relative to the cutter tip at least one radially and axially with respect to the body. This moves the cutter tip at least one of radially and axially with respect to the body of the tool. A second adjusting element operably by a second setting device may be provided to act on a second side face of the cutter tip.
Abstract:
With respect to a device on diamond hollow drills, the actual component (4, 8) of the drill (1) that forms the coupling to the clamping device of a drilling machine or an additional component that has a clamping device for the drill and a holder for coupling to the clamping device is developed as an adapter that can be adjusted and fixed in position with respect to its length. A rapid-action coupling for connecting the drill to a drilling machine and a device for adjusting the overall length of the drill unit are disclosed.
Abstract:
A backspot facing tool includes a shaft and a cutting element. The shaft has a first and second ends and a recess located near the first end. The shaft also includes an outer circumference and is centered on a first axis. The cutting element has an inner portion and an outer portion and is pivotally coupled to the shaft about a second axis. The cutting element is movable between a closed position and an open position.
Abstract:
A deburring tool is adapted to be rotatably mounted in a chuck of a drive motor to perform deburring operations. The deburring tool includes an arbor and a blade having a cutting head portion defined at one end thereof and a clip portion defined substantially at the other end of the blade opposite the head portion. The blade is mounted relative to the arbor such that the blade projects a predetermined distance from the arbor in an unstressed condition. The blade is sufficiently resiliently yieldable such that it can move inwardly with respect to the arbor during deburring operations. The clip portion is adapted to flex to provide a spring-like force acting along the blade toward the head portion to facilitate insertion and removal of the blade relative to the deburring tool without use of any tools.
Abstract:
A drill bit point storage system comprising a drill bit and at least one cavity in at least a portion of the drill bit for storing at least one drill bit point. The system can also include a coupling device for securing the drill bit point when the drill bit point is stored within the cavity of the drill bit. In one arrangement, the coupling device can be a cover positioned substantially around the drill bit in which at least a first portion of the cover can have a shape that can substantially correspond to a shape of said portion of the drill bit such that the first portion of the cover can be substantially adjacent to the portion of the drill bit. The first portion of the cover can be at least partially positioned over the cavity when the drill bit point is stored therein.
Abstract:
A tool for removing the dome portion of a nail pin anchor, rivet, or other fastener. The tool, which is powered by a power drill, has a drilling end with a slot to accommodate the nail of the anchor. The balanced drill bit has six cutting points. A collar surrounds the body of the tool, allowing the installer to position it properly. Free-wheeling bearings allow the collar to remain stationary while the drilling end is rotating.
Abstract:
A woodworking drill includes a slab-shaped blade and a blade handle connected behind a body of the blade. The top of the blade is shaped as a point of blade with shoulders on both sides of the point of blade. On the edge of the point of blade, the shoulder cutting faces and the blade that contact with the working object set the cutting guiding angles. A bending mechanism in the same direction of the drill's rotation is designed on both shoulder cutting faces. This design reduces contacting resistance or cutting resistance between bended shoulder cutting faces and working objects and enhances efficiency of clearing out saw dust. With the bended shoulder cutting faces, the drill can clear out saw dust more effectively, enhance cutting speed and working performance as well as prevent the abrasion to the drill.
Abstract:
A guide to center a screw or drill bit in the center of a hole of a countersink in a member to engage a piece under the member, the countersink having a downwardly tapered wall from the member to the hole. The guide has a body with a through hole and a tapered part that is to rest on the member tapered wall to align the through hole generally perpendicular to the piece. In a preferred embodiment the guide body tapered part is at an end of the body and the body is of frangible material and holds a screw in the through hole which fractures the body as the screw is threaded into the piece beneath the member. At least one slot is formed in the body along at least a part of its length between its top and bottom ends to facilitate the fracture of the body.
