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

The edges on this bit are very, very sharp, so be sure to take care when handling it. Its all too easy to slice yourself when taking the bit out of its case, or installing/removing the bit from the router. Used this bit to rout cutouts in copper countertops (the copper layer is about 1/32 thick). Even with a good bit, it is slow work, but this bit did the job, and left a nice clean edge on the cutout.

Great price point for a good quality bit for my CNC machine. Cuts clean and the bit is very sharp. My only comment or complaint would be that they would put a description label on the case for storage instead of the envelope.

While not a terrible bit it isnt any better than a standard straight 2 flute carbide bit. I was working with 3/4 ash, prepping it for gluing into panels. This bit was ok for light cleanup on the edges but thats about it, maybe removing 1/32 or 1/64 of an inch.

Excellent for getting way down into a design! Especially when grooving areas for slip in pieces like a two part frame I do - Nice to have a bit that my machine limits can work with also without having to place my router physically lower to reach - Leaves nice and clean cut walls and works it’s way through fairly easily - Definitely would recommend giving this a go! 9/10 a winner!
