EANOSIC Upcut Spiral Router Bit 1/4 inch Shank, 1/4 inch Cutting Diameter, Extra Long 3 inch Solid Carbide with Nano Blue Coating CNC Router Bits End Mill for Wood Cut, Carving

upcut bits are the only way to assure a clean cut at the edge.... due to how they cut... they cut upwards towards the shaft so in a handheld router, put the good side of the workpiece down in a router table or CNC do the opposite... this bit has produce superb finishes, highly recommended, great price point... 5 stars

Good quality bit. Perfect for my CNC operation.

I bought this bit rather than others of the same style because I needed the extra length. I was concerned about the durability due to the extra length of the bit. It has performed as expected, and hasnt broken. And has stayed sharp. A very good buy.

This bit worked great for my project.
