I was a little skeptical about purchasing this router bit as a beginner in the Industrial and Scientific field but I must say I'm pleased with the results. Thanks to my knowledge gained in practice, this router bit did not disappoint me. The cutting performance was precise AND flawless... the only downside was the price - a bit expensive. However, overall, I would recommend this router bit to anyone looking to produce quality work with efficiency..
Pros
Efficiently creates 4-inch diameter mortises with precision
I have never been disappointed with CMT bits. They have large carbides and work well. I bought this Porter cable door hinge attachment. It is ideal for 5/8 inch radius hinges.
