Bora, a division of Affinity Tool Works, just announced the Angle Master. The Angle Master takes the guesswork out of complex miter cuts by providing a precise measurement tool for both inside and outside angles, and allows difficult projects such as crown molding to be completed with ease and accuracy. Just measure the angle, divide the tool and transfer to a miter saw, band saw or table saw for a perfect cut on even the most complex angles. The Angle Master is ideal for a variety of finish carpentry applications, home remodeling, deck building and do-it-yourself projects.
