Great Product, Bought for doing binding rebates on Guitar Body and Neck. Only test cuts done at the moment, but so far very impressed with how clean the cut is. Also, my initial order got lost/delayed in the post, due to the current COVID situation. The guys at Radian tools dealt with my OCD need for updates really well, and sorted the problem beyond what was required. Thanks again Guys!

So good I bought the larger version too

I use several of Radian's router bits, mainly for electric guitar building. They are all made to exceptionally high standards and this 9.5mm x 12mm cutter is no exception. This router bit is perfect for routing clean, accurate pickup cavities and is a pleasure to work with.
Highly recomended!

Professional router bit. Ellipse is good shape so you can do different types of carves. I've used it to carve a guitar top then rounded over the top of the cut to make a dome. As usual a very well made tool.

For years I couldn't entertain the idea of paying £60 (including P&P) for a router bit, so I "managed" with cheaper offerings.
Then I saw Ben Crowe at Crimson Guitars using and praising the 4 flute, dual bearing router bit on his YouTube channel.
I decided to bite the bullet and ordered one and I have to say I could not have been more impressed with the performance of the cutter. The quality of the finish it produces is definitely worth the price.
If only I had realised years ago, I would have saved myself a lot of heartache.

This is one very well made router cutter! Incredibly sharp and accurate

Absolutely fantastic, smooth, clean.......excellent, without doubt the best router bit I have ever owned....functional tool and work of art in one.

I've been using Radian cutters for guitar making for over a year now and have been nothing short of blown away by the quality of the cut. This was highlighted when trimming end grain Wenge for a guitar headstock, just perfect, most standard cutters would have left the router screaming and with endless sanding to be done afterwards. With the radian bits, there's not even a suggestion of burning, chatter or tear out. The cut is vibration free and smooth as you like. Very impressive.

At this point I have, all of the 1/4" trimming bits, two or the 1/2" collet trim bits, three binding channel rebate cutters of various sizes and a chamfer bit. Fantastic stuff!

You get what you pay for with tools like these. Very happy

Great quality carbide and craftsmanship. Radiantools offer a sterling customer service and fast dispatch as well.

Another great cutter. Speedy delivery to boot.

After being recommended to try these out I feel I’ve made the right choice As the smoothness of the cutting is second to none.

I still have to use it but it looks like a tool made to last

So far I've only used for one small job, but very impressed with the clean and precise cuts.

This is a very well made and extremely accurate bit set. The bearings are spot on and give exactly the width of cut they are supposed to. The 3 flutes give very clean cuts even against the grain with no tear-out. Well worth the money.

Haven't had a chance to use this yet just the surfaceing bit but I'm Shure it's the way to go just by everyone else's reviews on you tube

Thickness on a budget

The tool is extremely sharp and cuts very clean! My only gripe was the bearing was a few thousandths different from the cutter. That may be by design and it’s certainly not the end of the world. All in all , Great product!

This is by far the best cutter I have ever used. On a hard maple guitar body, no tear out and zero burn marks, very clean finish. Will be buying more from Radian.

These are simply the best router bits available espacially for luthiers these days. I had to buy an 6,35mm collet (I hope this is right, I´m from Germany) for my festool router, which was pretty expensive, but absolutely worth every penny!

Great products, great service and highly recommend these guys.

Done a large batch of template cuts with this and had great results

used cheaper bits but never again these are the best for me

Fantastic workmanship..solidly built

The best

I'm very happy with the finish it makes, sharp, big bearing at the top makes work easier. Will buy more

A great router cutter, gives an exceptionly clean cut and is genuinely a 1 to 1 cutter leaving nothing to clean up.:+1:

Used it recently on a banjo rim with all kinds of crazy figuring. It handled it beautifully regardless of grain orientation.

3 Flute router bi

This router bit is great!! Along with all the other Radian bits to be honest. It was my first time using a router, and I has heard mixed things about them... one of those things being that they can be quite ‘grabby’ and aggressive. I was advised to invest in some good router bits, and after watching many guitar building videos, it was clear that Radian were the ones to go with. I used this particular bit for the majority of the pickup cavity routing, and then just finished off with one of the smaller 3 flute trimmers. The job was clean and super easy. Really satisfied and will always use these bits.

What a excellent router bit, I routed a guitar body with no problems at all using my router table. The finish was great due to the 4 cutters and required very little final finishing.

Smoothest cut I've seen, regardless of grain direction. Brilliant tool!

I have three radiant bits. They are excellent for lutherie. Quick delivery to Canada too.

Nicely made

Nothing beats these bits. This particular size is perfect for barely kissing that sharp edge off of corners

Excellent tool for an excellent result! Works well for a Strat style guitar body roundover!

Originally saw this company on a Crimson Guitars build video, and got a chance to use them during the guitar building course that I attended. Tried some sub-par bits on my own, but after that worked out badly I knew I needed to get the real deal! They work like a dream, thanks Radian!

It cuts really smoothly, and with 4 blades you don't have to go too slow. I think that adds to the precision. And also there is't much difference between the bearings so the cut is really equal both ways. It's just nice to have good bits like this to work with. Vilho / Kodian Guitars - Finland

This bit is unbelievable. My router feels like a new tool, it cuts like it never has before. I can work faster and the end result is ten times cleaaner: no marks, no burns, no nothing. Perfect tool

Brilliant product well made and sharp.

A great solid cutter, the smooth finish it produces with no burning needs very little finishing.
im building my set of routers - looking forward to the next one. Highly recommended.

Haven’t had a chance to try it but fit, finish and quality are excellent

you know how a bartender slides a beer down the bar top and it just glides smoothly to the customer at the other end? This bit is even smoother...

Clean cut!

This bit set is just what I was looking for! Delivered in Belgium in no time! Excellent.

Routed two sets of binding channels without incident. No further work needed because the finish straight from the cutter was perfect.
No climb cutting, just shallow cuts in succession. Result - no dramas and I am a happy bunny!

Cannot fault bits really good.
