Whether a 1 3/4 horsepower (HP) router is enough for your needs depends on the specific woodworking projects you plan to tackle. Generally, a 1 3/4 HP router is suitable for medium to large-sized projects and can handle many types of cuts and joinery work. However, if you primarily work with harder materials or require higher torque for more demanding tasks, you might want to consider a more powerful router. It's important to assess your specific woodworking requirements and match them with the appropriate power and features of the router.
