UCAN's 0.866 in. OD x 4 in. Stainless Steel-Wire Hole Cleaning Brush offers a straightforward way to incorporate mechanical brushing into drilled-hole preparation before adhesive is dispensed. Proper hole cleaning is an important step in adhesive anchoring because dust and drilling debris can interfere with the prepared hole surface and affect installation performance. The stainless steel-wire construction is suited to repeated professional use, while the compact brush profile allows it to work inside the specified drilled-hole diameter. For contractors, installers, and construction professionals using FLO-ROK® adhesive anchors, the SBR34 provides a purpose-built hole cleaning accessory matched to common 3/4 in. drilling applications.
