Abstract: A scarifying and deburring tool is disclosed adapted to scarify an outer surface of a tubing, pipe or fitting end and scarify and debur an inner surface of a member having an open cylindrical end such tubing, pipe or fitting end. The tool includes an elongated contoured handle with two inner surface scarifying brushes extending from opposite ends of the handle. The handle includes two outer surface scarifying brushes supported in spaced apart throughbores in the handle. A deburring plate is affixed to one side of the handle and includes an inwardly angled deburring scrapers aligned with and extending into respective throughbores. When a tubing, pipe or fitting end is inserted in a throughbore and seated against the corresponding scraper, the end is deburred when the tubing, pipe or fitting is rotated with respect to the tool. The deburring plate includes an opening that functions as a key for opening and closing "B" type acetylene tanks.

Abstract: An elongate, abrasive strip element is produced by winding an abrasive monofilament, or bundles thereof, back and forth in a zigzag pattern from side to side of the strip, and chain stitching together adjacent transverse sections of the monofilament, or bundles thereof. The resultant strip is easily rolled or coiled about a transverse axis, but resists bending about a longitudinal axis, whereby it can be manipulated readily to form brush faces of various configurations. The warp yarns which are used to produce the chain stitches may be produced on a knitting machine which can be cammed to vary the number of stitches between adjacent transverse strands of the monofilament wefts, thereby selectively to vary the density of the brush faces produced from the strips, and also to vary the configuration of the abrasive strip itself (i.e. to produce it in linear form, circular, truncated-conical, etc.). The linear form of the strip may be severed medially of its edges to form two, identical bristle strips, each of which may be wound in convolute form, for example, and may be embedded at one side (e.g. by molding) in an elastomeric base to form a disc type brush. Other brush configurations are also disclosed.
