I recently purchased this router bit and I must say that I am impressed! As a result of using this product, I found that it was able to cut through dense wood with ease, which is precisely what I needed it for .The bit also held up well against wear and tear, which is great for a tool I use frequently. The only downside is that its a bit expensive but I believe the quality justifies the price. Overall, a great investment for anyone in the industrial and scientific field..
