Review on 🔪 Precision Cutting with Amana Tool RC 1148 Insert V Groove by Brian Whitmore

I bought this bit after trying several cheaper 60 degree bits and noticing the angles were wrong (one was 58 and the other was 61). I wanted to try a more professional piece, but when I got this one, it felt like the blade wouldn't go all the way down to get the exact center of the cutting diameter. Because of this, a 1 mm thick dome appears in the lower part of the slices. Imagine the drill deviates by 0.5 mm and makes a complete revolution. The point is to make a circle 1mm in diameter and leave the material in the middle. You can see it in the picture I posted. You can also see this by simply rotating the cutter by hand and watching the tip of the blade move from side to side. There is no play in my router and this does not happen with my Amana Tools 90 degree bit or any of my other bits. I have tried removing the blade, cleaning the blade seat and replacing it. It also appears that the drill may have been used earlier due to scratches on the painted surface and what appeared to be sawdust under the blade. Since the screw hole doesn't leave much room for maneuver, the blade cannot be adjusted any further. All in all, I think maybe it's just what I have, but it's definitely something to watch out for. This can have unwanted effects on V-threads, and if left unnoticed, it can ruin a large project and your day. In short, the quality of the bit itself seems good, but make sure to manually rotate it on your router and check if the tip of the blade is misaligned before making any cuts.
