“Great product. We've just finished creating a mirror for a client made from wenge, which is a pain to work with due to its hardness. The Radian router bit made it a breeze..”

“I have just been using the guided cutter I bought recently and it was < brilliant. I was doing pattern routing onto 19mm MDF and it did the job with ease and instead of having to leave a maximum of about 1mm it coped easily with 2 and even 3mm and left a perfect finish.”

“I have been using the 19mm x 51mm four-flute dual bearing router cutter to profile 18mm birch ply, and to finish 76mm x 64mm cutouts in 24mm thick maple. The cutter produces fine shavings and leaves a smooth surface with no scorching in the internal corners. Iíve found it a pleasure to use.”
