Review on 🛠️ SpeTool Engraving and Cutting Tools for Compression Diameter Grinding by Sean Burnett

Great product so far! I use this bit on my Shapeoko XL and needed a new 1/4" bit to cut profiles. As you can see in the picture this bit was used on the left insert and my old Amaña 1/4" Drop -Thread bit was used on the right insert. As you can see the difference when you zoom in, this new bit is far superior to amana. But Aman's set of teeth is older and most likely a bit boring, and just a run-down set of teeth too. But I have to say that I am very satisfied with these Spetool compression bits. Perfect beat!
