An apparatus for deburring the marginal edge of a cylindrical body, comprising a substantially enclosed cylindrical housing having (i) a circular hub, (ii) a continuous, open channel circumscribing the hub, and (iii) a circumferential rim disposed radially from the channel. The channel has (i) an inner sidewall defining the outer wall of the hub and an outer sidewall defining the inner wall of the rim, and (ii) a laterally disposed annular boss interconnecting inner and outer sidewalls so as to connect the hub and rim. A plurality of first, spaced elongated slots and second, spaced elongated slots are formed at opposed peripheries of the boss, and the first slots open through a portion of the inner sidewall and the second slots open through a portion of the outer sidewall; and the first slots are offset from the second slots and disposed radially outwardly from the first slots. A plurality of first pins are seated in the first slots so that a portion of each of the first pins protrudes outwardly from the periphery of the inner sidewall and into the channel; and a plurality of second pins seated in the second slots so that a portion of each of the second pins protrudes outwardly from the periphery of the outer sidewall and into the channel, whereby the second pins are disposed concentric to and outwardly from the first pins and offset therewith so that each of the second pins is disposed between adjacent first pins. A spring biases the first pins and the second pins radially in opposite directions toward each other and to be displaceable radially in opposite directions.
