For those who are struggling with a burned or marred line from the pilot try this. Route before you finish sand the thing! Glue the binding in, then sand the burn or line out. Climb cut with this bit to eliminate tearout. Make shallow climb cuts at first. I've been building for many years and there is a learning curve like no other in the luthier field. These bits are awesome I have been using them for years.
Do not think of using this. It needs a bearing, not just a shaft guide. Gouged the wood the first time I used it and then it got dull immediately anyway.
This bit seemed expensive to me until I got it and used it. It cuts exceptionally well and you get what you pay for, right? Some people have complained about the pilot leaving a mark. I have found that if you let it cool off for a minute here and there you won't have that problem.
This was an excellent cleanup tool for those where the depth and height may be a bit off from using your binding bit/bearing purchased from Stewmac.com, especially around top back of a guitar where the neck and body meet. The curve is steeper here, so instead of using a wedge while binding, just use this bit in your Dremel tool to tweak the channel a bit until the binding fits flush. It cuts a nice neat channel, although you do have get used to it as likes to wander a bit if you go too fast. If you go slow you will get a good looking clean channel every time
Used this to route the binding channel on the headstock of my acoustic guitar project. Yes, there is a small mark left behind on the wood from the guide, but that did come out quite easily when sanding the binding flush with the headstock.
This bit works as advertised providing extreme care is used on end grain. A spiral cutter would work much better.
Like some others I am not very light handed when it comes to routing. I had sanded my instrument ready for the paint job and routed with this bit for the binding and when I got through I noticed a fairly deep ring and dark burn marks all around the instrument which I had to sand out which was no easy task. It really needs a bearing on the shaft to eliminate this.
Worked perfectly in my dremel and cut the binding channel thickness as advertised. Unfortunately it was not until halfway through routing that i noticed the guide at the bottom leaving a groove in my body under the channel. Upon inspection i found the shaft slightly bent when rotating in the dremel causing a warp in the spin. Cuts great but QC for these should have better inspection.
This router bit took all the hassle and guess work out of preparation for binding installation. Great product.
I used it for building 3 les paul replica (mahogany and walnut). After sanded the sides smooth, I've made the binding channel on the lowest speed possible. The bit leaves deep marks, sometimes burned in. I won't use it anymore, be careful with that.
