Abstract: A core drill bit can include a first region and a second region. The first region can include abrasive particles in a first bond matrix, and the second region can include abrasive particles in a second bond matrix. The first region is connected to the second region. A composition of the first bond matrix can be different from a composition of the second matrix. In a particular embodiment, the first bond matric can include a Co-containing material.

Abstract: A cutting wheel includes a body having a bond material. The bond material comprises at least about 31 vol % of a total volume of the body. Additionally, the body includes abrasive particles contained within the bond material. The abrasive particles include a first type of abrasive particle including black alumina with at least about 10 vol % of a total volume of the abrasive particles including black alumina. In some instances the cutting wheel can include a chop saw, while in other situations, the cutting wheel can include a cut-off wheel.

Abstract: An abrasive tool can include a bonded abrasive including a body and a barrier layer bonded to a major surface of the body. The body can include abrasive particles contained within a bond material. The barrier material can include a metal-containing film. In an embodiment, the barrier layer may further include a polymer-containing film. In another embodiment, the barrier layer may include a biaxially oriented material. The abrasive tool may be formed such that the barrier layer is formed in-situ with the formation of the bonded abrasive.

Abstract: The present invention discloses an improved tool, which comprises a reinforced member; and a resin layer is coated on the reinforced member, wherein the weight of the resin layer per unit area of the reinforced member may be less than 90 g/m2. The weight of the resin layer may be less than 15% of the total weight of the improved tool. The present invention dramatically reduces the production costs while maintaining the application performance unchanged.
