This bore brush has 0.018" stainless steel wire staple-set into drilled holes around a 1-1/2" diameter PVC machined core. This high-quality brush can be hand or machine operated and is designed to clean both the wall and the bottom of a hole when a twisted-in-wire spiral brush is not strong or thick enough to provide sufficient abrasion. The brush diameter is 4-1/2" and the brush length is 5-3/4". National pipe thread (NPT) size is 1/2". Other bore brush sizes are available upon request.
