Abstract
An abrasive tool has a body including an abrasive portion having abrasive grains contained within a matrix material, and a first reinforcing member contained within the abrasive portion, wherein the body comprises a porosity variation difference through at least half of a thickness of the body of not greater than 250% from a mean porosity of the body.

An abrasive tool comprising:
- a body including:
- an abrasive portion having abrasive grains contained within a matrix material;
- and
- a first reinforcing member contained within the abrasive portion, wherein the body comprises a porosity variation difference not greater than 250% based on a mean porosity as measured between a first plane extending along an interface between the first reinforcing member and the abrasive portion and a second plane parallel to and spaced apart from the first plane and extending entirely through the abrasive portion along a non-intersecting path with the first reinforcing member.
