The new woodworking edge ruler simplifies your life by wrapping around the edge of inventory and providing precise proportions on both sides. Even the most experienced woodworker faces challenges with precise angular placement on larger panel projects. You can try to extend the production line from a small protractor, but even a small error will lead to a bigger error, the more the production line will be extended. Our brand new precision ruler offers unparalleled precision for your panel layout work. Just push the head to the angle you want then straight. The head can be adjusted between 0 and 70 and locks securely every 5 (plus 22-1/2 and 67-1/2) to give you an accurate reference angle or length. > The secret to the T-Square is the series of precision-machined indexing holes and the close-tolerance, spring-loaded indexing pin that engages them. The stylus snaps into place, giving you peace of mind that it's just fine. The saw blade has the same exclusive serrated notches as our new precision squares for the stainless steel woodworking. There is a notch every 16 inches along the blade. Simply drop your pencil into the notch and slide your head along the edge of your rod for a perfectly parallel line.
