    1/4 spiral bit

    Fantastic bit, cuts very smooth without any issues!

    Excellent Service & Product

    I had issues with my royal mail delivery and Radian sales immediately sent out a replacement, when the replacement came the quality is top standard and wax dipped to keep it fully protected as you get with only the best. Now my go to outlet for router bits.

    Three flute rebate router bit for guitar binding

    Superb in every way. Super clean cut in quilted maple even on the end grain. I am a carpenter/joiner of 20+ years and these router bits are worth every penny. Arrived on time, would highly recommend and this will be the first place I will look for any of my routing needs in future. Thankyou radian tools!

    Einfach super!

    Super saubere Schnitte! Perfekt für den Gitarren Bau. Werde bald noch mehr Fräser bestellen. Danke für die tollen Produkte! Grüße aus Deutschland

    A game changer

    I've been building electric guitars for a few years now and gradually improving my workshop. One of the big challenges is to accurately shape the guitar body using templates. At 45 mm thick this has been a problem for my router set up but not any more. With this bit I can cut the full depth in one pass, and, by alternating the bearing used I can always cut with the grain and eliminate tear out on those sharp corners.
    OK, so it cost more than my first router but well worth it, truly for me a game changer.
    Did I mention it's razor sharp?

    3 Flute Rebate Bit Set 1, 1.5, 2, 2.5, 3mm

    Thank you!

    Here in the U.S. no one seems to make a three-flute top-bearing router bit in this length -- the best I've been able to find is two-flute, if they make this length at all. I was happy to have found & purchased the Radian bit -- it's exactly what I was hoping for. The cuts are smooth and it never grabbed, even when cutting through lots of material. It's replaced the Freud two-flute bit in my arsenal.

    Awesome. Definitely buy again. Thank you.

    Just the job!

    This rebate set is of high quality and reasonably priced. It cuts binding channels cleanly and accurately. It is going to be a real benefit for my future guitar making projects.


    Great Router bit. Leaves a beautiful finish. I will be looking to slowly upgrade all my other router bits as they wear out

    Absolute pleasure to use

    Bought this 9.5mmroundover to finish new beech worktop in kitchen. Cut so easily had to check it was doing the job. Beautiful cut, almost zero resistance when moving the router. Finish is smoother than sanded. Not cheap option but worth every penny.

    Amazing quality and precision.

    Guitar binding router bit

    Used this for 1.5mm guitar binding. Works really well! Very sharp. Remover the way with a wooden tooth pick

    Absolutely makes the cut!

    So great and cuts very smoothly! I wish I had bought a couple more bits. Next time I’m taking them all!

    4 Flute Dual Bearing Router Bit 19mm x 51mm

    Perfect tool for the job !

    By far the simplest and cleanest way to route a beautifully sharp binding channel . Can't stress how much easier this has made the binding process.
    Zero tear out and perfectly even depth , makes this essential for any luthier.

    Absolutely brilliant

    I’m an amateur guitar builder and the router bits from Radiantools are an absolute god send, they give a very clean cut that requires very little sanding afterwards. I highly recommend them
