A honing tool arrangement which includes a tubular shaft to one end of which can be attached a honing tool and the tubular shaft and the honing tool are capable of being reciprocated and rotated, a control rod in the tubular shaft and associated with a piston and cylinder device to cause fast feed longitudinal movement of the control rod relatively to the tubular shaft to cause fast increase and decrease of the effective cutting diameter of the honing tool and disengageable screw means between the tubular shaft and the control rod and rotational brake means associated with the control rod and capable of "braking" the rotation of the control rod relative to the tubular shaft when the screw means is engaged to cause slow feed longitudinal movement of the control rod relative to the tubular shaft and thus to cause a slow increase and decrease of the effective cutting diameter of the honing tool.
