A pipe cutter with gauge and reamer/beveller of the cut edges of pipe. On the body of the pipe cutter there is at least one gauge; between it and the body a cavity is delimited capable of accepting the end of a pipe (t); each gauge having on its end a mouth that varies its diameter between a minimum (d1) at its base and a maximum (d) that coincides with the gauge of the pipe (t) it accepts. There is also at least one blade on each existing gauge or on a beveller equipped with one or several portions (S) with at least one blade on each of them. A pipe (t) is inserted in the corresponding gauge, first gauging the diameter of its cut edge and then the blades simultaneously bevel and ream the cut pipe (t) edge.

The present invention generally relates to fasteners for securing an object to produce a straight line cut of the secured object, including a square cut of a secured pipe. More particularly, the present invention relates to fasteners for securing objects of various sizes and/or shapes where the object may be in almost any location. The fastener has a gap to guide a saw blade to produce a straight-line cut of the secured object. In some instances, the fastener may retain both pieces of a cut workpiece in place after the workpiece is cut. In some instances, the fastener may prevent the saw blade from cutting beyond the fastener.

A rotational cutting tool includes a connecting end for engaging with a driving tool and a cutting end for engaging with the work piece. The connecting end and the cutting end rotate about the rotation axis upon rotation of the rotational cutting tool. An inner periphery of the cutting end defines a receiving space for receiving the work piece. The receiving space has a conic surface which extends radially and obliquely with respect to the rotation axis. The receiving space includes a first ridge forming at least one cutting edge for trimming the workpiece and at least one slot allowing trimmed pieces from the workpiece to exit from the receiving space. The first cutting edge extends radially and obliquely with respect to the rotation axis. The first cutting edge extends curvedly and has a curved contour.

A redressing device (100) for redressing a tapered portion (12) of an orthopaedic implant (10) comprising: a grinding member (110) adapted to engage the tapered portion (12); an adjustable guide element (130) for defining, at least in part, the degree of redressing required for said tapered portion (12) by a user; and a drive shaft (120) for driving movement of said grinding member (110). A device for retaining debris produced during redressing a tapered portion (12) of an orthopaedic implant (12), a surgical kit for redressing a tapered portion (12) of an orthopaedic implant (10) and a method of redressing a tapered portion (12) of an orthopaedic implant (10) are also provided.

A deburring tool includes a deburring head and a shaft portion connected to the deburring head. The deburring head includes a conical hollow body, a primary cutting edge and a secondary cutting edge both formed on the conical hollow body. The conical hollow body has at least one flute extending between interior and exterior conical surfaces of the conical hollow body, and at least one recessed cutout defined in the interior conical surface. The primary cutting edge is formed at a junction of a wall surface of the flute and a bottom surface of the recessed cutout. The secondary cutting edge is formed at a junction of a wall surface of the recessed cutout and the interior conical surface.

A rotary cutter for cutting damaged threads of a bolt includes a body rotatable about a rotating axis and having a connecting end and an operative end. A first cutting blade is disposed on an inner periphery of the body facing a cutting space extending along the rotating axis from the operative end towards but spaced from the connecting end. The body further includes a virtual projection plane perpendicular to the rotating axis. A first virtual plane passes through the first cutting blade and extends perpendicularly to the virtual projection plane. A virtual circle and a first virtual reference line are located on the virtual projection plane. The first virtual reference line intersects the rotating axis and passes through an intersection of the first virtual plane and the virtual circle. An angle between the first virtual reference line and the first virtual plane is between 5 and 40.

More particularly, the present invention relates to fasteners for securing objects of various sizes and/or shapes where the object may be in almost any location. The fastener has a gap to guide a saw blade to produce a straight-line cut of the secured object. In some instances, the fastener may retain both pieces of a cut workpiece in place after the workpiece is cut. In some instances, the fastener may prevent the saw blade from cutting beyond the fastener.

A power tool includes a housing, a motor, an output member driven by the motor, and a reaming attachment coupled to the output member. The reaming attachment has a front end portion selectively driven in rotation by the output member to drive a fastener into a workpiece, and a reaming portion selectively driven in rotation by the output member to remove material from an end surface of a conduit. A rotational motion sensor in the housing is operable to detect rotational motion of the housing about an axis. A controller receives a signal indicative of rotational motion from the sensor, determines a direction of the rotational motion of the housing, and drives the motor in a direction corresponding to the direction of rotational motion of the housing.

A deburring tool has a hollow top portion having an interior conical surface and an exterior surface. The exterior surface of the deburring tool is preferably conical. The top portion has a plurality of flutes formed therein and extending between the interior and exterior surfaces. Each of the flutes has a cutting edge formed at the interior conical surface. In operation, rotation of the deburring tool about a longitudinal axis removes burrs projecting from bar stock contacting the interior conical surface. A method of deburring bar stock comprises: (a) rotating the deburring tool about a longitudinal axis, and (b) contacting the bar stock to the deburring tool interior conical surface.
