The Bosch DAF220K Miterfinder Digital Angle Finder Kit provides the versatility and convenience of four tools–angle finder, cut calculator, protractor, and level–all in one package. This updated Miterfinder now features angle memory for repeated use, simple miter cut calculation, and expanded input range for compound cut calculation. Ideal for use with any miter saw, the DAF220K also features a digital readout, leg extension, and more, making it a perfect choice for carpenters, re-modelers, and contractors. Designed for professionals or the weekend handy dad, the DAF220K offers 4 Tools in 1–an angle finder, cut calculator, protractor, and level–for tackling a range of trim and verification projects on crown molding, countertops, rooftops, and more. The angle finder measures the exact angle of an existing structure or workpiece, while angle memory stores measurements over repeated uses. The protractor helps you correctly position your workpiece or intended cut line, and the vertical and horizontal spirit levels–accurate to 0.05 degrees–help you keep things properly balanced.The DAF220K also features a compound/simple cut calculator that helps you achieve a precise fit each and every time. The calculator’s compound feature determines exact miter and bevel angles and has a versatile cut input range of 0-180 degrees. And because the calculator stores measurements (such as crown molding spring angles), you won’t have to position the tool every time you use it. Just press a button to display compound miter and bevel cut angles. Makes a great gift for men.
