Incra PROTRAC06 6-Inch Precision Marking Protractor

The Incra 6-Inch Precision Marking Protractor lets you plot any angle with ease and absolute accuracy. A metal T-Bar and see-through cross hairs provide perfect alignment against the edge of your work-piece. Remove the T-Bar to work on flat surfaces or to use the 6-inch centering scale with micro-fine marking holes at every 1/32 inches. This marking protractor has micro-fine guide holes at every 45-, 30-, 22.5-, 5-, 1-, and 0.5-degree intervals. Four angle scales, including one for marking narrow stock, suit every need. It's easy on the eyes, incredibly accurate, and just plain fun to use.
