Back Chamfer: 1/2" Dia, 90 &deg MPN:02703080

The back chamfer is a valuable tool in machining and tooling industries for creating chamfers or beveled edges with a 90-degree angle at the top of holes or blind-ended holes that prevent burr formation during drilling, tapping, milling or counterboring processes. This increases precision, minimizes friction, reduces risk of breakage, and enables smooth assembly while improving the strength of fasteners like screws, rivets or bolts when joined with materials like metal, plastic, or wood. The back chamfer provides improved accessibility for secondary operations or inspections in aerospace, automotive, manufacturing or other industries that require exacting tolerances and quality control standards in their products and assemblies.
