Great projects start with high-quality cuts, and you can make those cuts more easily than you ever imagined using your circular saw plus the Rip-Cut circular saw edge guide. The Kreg Rip-Cut turns your circular saw into a precision edge-guided cutting tool that makes straight, accurate, repeatable cuts in plywood, MDF, and other large sheets. With the Rip-Cut, you can cut with the confidence you want and the precision you need. The Rip-Cut easily makes straight, accurate, repeatable cuts without measuring, marking, or having to keep the saw on the cut line. The Rip-Cut does this with a long edge guide that follows the straight edge of the sheet you are cutting. So, all you have to do is lock the saw in at the measurement you want up to 24 In. using the built-in measuring scale and then make your cut. With a built-in measuring scale, you don't have to measure and mark each cut, either. Just lock the saw sled at your desired cut width, and you're all set, whether you need to cut one piece or make multiple pieces of the exact same size. Plus, the Rip-Cut makes it easier to cut down large sheets by yourself. The Rip-Cut is very easy to use. Simply mount your saw to the universal sled it accepts most left-blade or right-blade saws and then slide the sled onto the aluminum rail. After a simple one-time calibration, you can lock in your cut width (up to 24 In.) using the measuring scale and precision cursor. Then, just hold the edge guide against the edge of your sheet as you guide the saw. You'll get straight, accurate, repeatable cuts easily every time.
