Eliminate the guesswork when transferring or cutting complicated skirting board or cornice angles with the Milescraft AngleFinder™. This tool conveniently and quickly sets up on your mitre saw and transfers the angle to your blade. It works on both inside and outside corners and features retractable edge guides that register the angle finder tight against the edge of your workpiece. A lever locks in place to assure accurate cuts. Quickly set mitre saw angles by resting the angle divider against your blade. Use it to set the angle on anything in your shop, including table saw blades and band saw table surfaces. It finds angles between two points on inside or outside corners and is used for transferring and replicating marks and angles accurately.
