Transform your circular saw into a high-performance, track-guided cutting tool with the Kreg Accu-Cut Track Guide. Start projects right by making straight, accurate, splinter-free cuts with your circular saw. It rips, crosscuts, and makes angled cuts up to 50 inches long in plywood, MDF, and other large panels with super-simple setup, precise accuracy, and amazing control. The Accu-Cut guides your circular saw along an aluminum track that keeps the saw moving in a straight line easily. Setup is simple by just aligning the track with your cut line. No clamps are required to hold the track in place thanks to dual guide strips with an anti-slip coating to prevent slipping and an anti-chip feature to prevent splintered cuts. The track also makes it easy to make straight cuts on sheets that don't have a straight, flat edge. The starting block supports the saw and allows normal blade guard operation.
