A deburring tool for deburring an interior and/or exterior of a work piece wherein said deburring tool is moved in a rotatory and/or translatory fashion during use, comprising a tool shaft ( 1 ) having a clamping end ( 2 ) and an end ( 5 ) with an internal support member ( 6 ) including an elastomer material, and wherein said support member supports at least one support surface of a blade member ( 21 ) with a cutting edge ( 3 ) that is movably arranged in the opening ( 10 ) and radially acts upon the cutting edge ( 3 ) with a spring force, wherein the support member ( 6 ) is arranged on the shaft end ( 5 ) on the tool side in form of a rigid bearing, and wherein a tubular shaft section ( 11 ) is connected to the tool shaft ( 1 ) by one or more connecting elements ( 13 ) holding the blade member ( 21 ) that is movably supported in the opening ( 10 ) and loosely adjoins the surface of the support member ( 6 ) with a play ( 8 ), wherein the surface of the support member and the surface of the blade member ( 21 ) always differ geometrically with respect to their shape and dimensions, and wherein a liquid or gaseous medium or a liquid/gas mixture that is pressed into a through-bore ( 12 ) of the tool shaft ( 1 ) causes the cutting edge ( 3 ) to move outward.
