Detailed Review
The Starrett 827 Edge Finder is a precision locating tool designed for machinists and fabricators who need an accurate way to find workpiece edges and centers. It solves the challenge of setting up reference points quickly before milling, drilling, or scribing, making it a reliable addition to any machine shop setup.
Built from hardened tool steel, the body and contacts are ground and lapped to close tolerances for diameter and concentricity. This construction ensures long-term wear resistance when touching off against metal parts. The unit features a .500-inch body diameter and a .200-inch contact diameter, offering a standard size that fits common machine holders while delivering precise locating capability.
Versatility is a major strength of this edge finder. It is designed to locate edges on flat surfaces, straight edges, shoulders, and grooves, as well as round work such as dowels or circle centers. Beyond standard machining setups, it can also be used to scribe lines directly onto materials like studs or wallboard, and it comes packed in a protective case to safeguard the precision surfaces from damage when stored.
As a single-end mechanical tool, it is limited to its specific .200-inch contact size, which may not suit setups requiring smaller or larger contact diameters. Buyers will also need a toolholder or chuck that accommodates the .500-inch shank.
Verdict: The Starrett 827 is an outstanding choice for machinists and metalworkers who need a dependable, American-made tool for locating edges, finding round centers, and scribing lines with repeatable accuracy.
