🔍 The inlay kit’s brass guide bushing is designed to fit routers that accept the standard Porter-Cable style guide bushings (a very common size in the industry: 1-3/8\" outer flange). Many routers either have a base that accepts these directly or offer an adapter plate. The kit even provides a centering pin to ensure the bushing is dead-center in your router’s base:contentReference[oaicite:44]{index=44}. So if you have a typical woodworking router – Bosch, DeWalt, Makita, Porter-Cable, etc. – you can likely use this kit. Some compact trim routers might need a separate base or adapter that can hold a guide bushing. It’s always good to check your router manual or baseplate – if it mentions guide bushings or template guides, you’re set. In summary, the SpeTool inlay kit works with most standard routers; in a few cases you might need an inexpensive adapter, but the sizing is industry-standard.:contentReference[oaicite:45]{index=45}
