Abstract

A downhole abrading tool having a body with a first end (22) for connection to a drill string, a cutting end (23), a drilling fluid passageway (26), a restrictor (30) disposed within drilling fluid passageway, and an indicator chamber is disclosed. Upon exposure of the indicator chamber (19) to a well environment due to excessive wear on the cutting end, the restrictor (30) is actuated. Actuation of the restrictor restricts the flow of drilling fluid from the drilling fluid passageway (26) into the well environment. The restriction of flow of drilling fluid from the drilling fluid passageway (26) causes a pressure increase in the drilling fluid flowing through the well that can detected by an operator of the downhole abrading tool. The pressure increase provides an indication to the operator of excessive wear on the cutting end of the downhole abrading tool so that the downhole abrading tool can be removed from the well and replaced.
