AMANA TOOL offers a carbide-tipped countersink with non-marring, adjustable ball-bearing depth stop. The new tool creates pilot holes and varied-depth countersinks in a variety of materials without causing burnout or other marks.

Users can adjust the depth of both the pilot hole and countersink so that the resulting opening is either flush with the surface or recessed. The resulting countersinks can be shallow to accommodate a only a screw or deeper to allow for insertion of a plug. The countersink also features an opening to allow for chip evacuation. The tool sells for about $37 and is designed for use in a drill press, handheld drill or boring machine. For information, visit www.amanatool.com.
