Carbitool is an Australian company that makes a variety of cutting tools including router bits. Their quality is as good as any brand I've used and they have a great range. My order from AP Workshop arrived yesterday and I couldn't be happier with their service. I placed my order Sunday, received personal email confirmation that night, email at dispatch, and they arrived Thursday. Because of the size of the order it was all 30% off RRP and shipping was modest.
Among the more interesting bits in the collection is this stacked classical rail and stile bit. The most expensive and complex bit in the collection should prove invaluable forming cardboard doors and the newell posts.
