Detailed Review
The Starrett 827 Edge Finder is a dedicated layout and alignment tool engineered to help machinists and fabricators accurately locate reference points on a workpiece. Designed for fast and straightforward operation, it solves the challenge of finding true edges and center points before machining. It fits anyone needing reliable positioning on a milling setup or workshop project.
Constructed from tool steel, both the body and contacts are fully hardened, ground, and lapped. This careful finishing maintains close tolerances for diameter and concentricity, ensuring consistent contact points against the stock. The tool features a .375-inch body diameter paired with a .200-inch contact diameter, making it suitable for standard chucks and collets.
Versatility extends across several surface shapes. You can use it against flat faces, straight edges, shoulders, and inside grooves, as well as on round stock such as dowels or the centers of circles. Beyond machine setups, it is also useful for scribing layout lines across surfaces like studs or wallboard, and it arrives with a protective case for safe storage.
Because this model features a single .200-inch contact tip, it provides one dedicated measuring size rather than multiple tip configurations. The listing does not specify overall tool length or total weight, focusing instead on its handy, lightweight build and precise machining tolerances.
Verdict: The Starrett 827 is a dependable choice for machinists and tradespeople who need quick, accurate edge finding and center location. Its hardened steel build and protective case make it a durable addition to any tooling collection.
