Festool 201185 Carvex Jigsaw Circle Cutter Set, Imperial is designed to work seamlessly with all Festool Carvex jigsaw models, allowing you to cut circles ranging from 4-3/8 inches up to nearly 10 feet (9' 10-1/8") in diameter. This versatile set includes the optional Guide Rail Base Adapter and Circle Cutter, making it an essential accessory for precise circle cutting tasks. The Base Adapter attaches to the jigsaw without the need for tools and can also be used to connect your Carvex jigsaw to a Festool guide rail, enabling extremely straight cuts in either direction when not cutting circles. The Circle Cutter conveniently rolls up for compact storage, ensuring it’s easy to keep organized when not in use. For optimal performance, Festool recommends using a scroll-type blade, such as the S 75/4 K or S 50/1.4 FSG, when making circle cuts. Manufactured in Germany, this set combines precision engineering with practical design to enhance your cutting projects. Model Number: 201185
