摘要： A rotary cutter for cutting damaged threads of a bolt includes a body rotatable about a rotating axis. The body includes an inner periphery delimiting a conic cutting space. The body further includes at least one cutting blade, an evasive groove, an evasive portion, a scrap discharge groove, a scrap guide groove and a scrap discharge orifice on the inner periphery delimiting the cutting space. The at least one cutting blade forms a ridge. The evasive groove and the scrap discharge groove are respectively located on a rear side and a front side of the at least one cutting blade along a circumferential direction of the inner periphery of the body. The scrap guide groove extends between the evasive groove and the scrap discharge orifice.

摘要： A pipe spinning power drill accessory a stem, shaft, first knurled assembly, second knurled assembly, first state, and second state. The first knurled assembly and the second knurled assembly are each cylindrically shaped. The first knurled assembly is centrally affixed to the stem. The shaft is centrally affixed to the first knurled assembly opposite the stem. The second knurled assembly is centrally affixed to the shaft opposite the first knurled assembly. The first knurled assembly and the second knurled assembly each selectively expand laterally. In the first state, the first knurled assembly and the second knurled assembly are each not laterally expanded. In the second state, at least one of the first knurled assembly and the second knurled assembly are laterally expanded. The stem is configured to be inserted into a chuck of a power drill. The stem is cross-sectionally hexagonally shaped and includes a region of decreased diameter.

摘要： A chip scattering prevention cover (1) is attached to a head portion (6b) of a rotary cutter (6). The cover (1) includes an annular portion (1a) configured to be detachably fitted over an outer peripheral edge of the head portion (6b), and a plate portion (1b) extending inwardly of the annular portion (1a) from an inner circumference portion of the annular portion (1a). The plate portion (1b) is configured to cover a region of a cutout gap (6e) of the rotary cutter (6) corresponding to the head portion (6b) with the annular portion (1a) being fitted over the head portion (6b). The annular portion (1a) and the plate portion (1b) are flush with a surface of the head portion (6b) when the annular portion (1a) is fitted over the head portion (6b).

摘要： Adjustable feed mechanisms, machining assemblies including the same, and associated methods. An adjustable feed mechanism includes a plurality of cam segments and a cam lifter configured to pivot each cam segment about a corresponding cam pivot point. An adjustable feed mechanism additionally includes a cam follower and a feed output assembly. The cam follower moves along the cam segments sequentially and is pivotally coupled to the feed output assembly. The cam follower pivots through a cam activation angle when moving along a given cam segment to produce the feed output. A machining assembly includes a mount assembly, a rotary element, and an adjustable feed mechanism. A method of utilizing a machining assembly to machine a work piece includes engaging the work piece with a machining assembly, positioning the tool head with respect to the work surface of the work piece, and machining the work surface.

摘要： A pen milling device and a method for milling pen blanks therewith. The device has a body selectively engageable with a rotating apparatus. A replaceable cutter is engaged with the body such that a cutting edge thereof extends outwardly beyond the body's end surface. The cutter has multiple cutting edges and may be reoriented relative to the body if a presented cutting edge becomes dull or damaged. A reamer extending outwardly from the body includes at least one flute. As the device is rotated, the cutter removes material from a pen blank and the reamer removes dried adhesive from a bore of a pen tube secured within a hole defined in the pen blank The device removes all of the pen material extending between an end of the pen blank and an associated end of the pen tube.
