Arcus is the developer of a new shape in a circular saw blade that has a new cutting direction. The unique contoured design of the blade cuts a radius unlike a traditional circular saw blade that is designed to cut straight. The Arcus® vision is to make high quality blades and accessories for making difficult projects that require a radius cut easier. Today ARCUS® Inc. manufactures the wood cutting, masonry diamond and steel cutting blade. To enhance the contoured shape blade accessory tools were developed like the Compass Guide helps to perfect a precision cut circles since it is difficult to follow a curve line while cutting.
