SpeTool Extra Long CNC Spiral Router Bits with Up Cut 1/8 inch Cutting Diameter, 1/4 inch Shank 3 inch Extra Long HRC55 Solid Carbide End Mill for Wood Cut, Carving

Worked while it lasted, it didn`t last very long. 3 uses

I use this for cutting inlays in hard maple and walnut. Worked great.

this bit has worked very well so fare

After three uses this bit broke in half. I was using it on a routine cut and it broke in half. I am not satisfied with this bit

Worked well but broke after a few uses (lasted one day). Price is much too high for the quality.

Broke immediately. Super flimsy!!! Get a descent brand because these are junk

I own quite a few of high end bits. From different companies who reach out to Instagram influencers. I bought these in a whim to get me through a project. I was amazed and how well they cut for 1/4 the price of my expensive bits that cut like crap. I highly recommend these bits and will keep buying them to run in my cnc

In middle of cut with cnc in hard wood the bit broke where it makes the transition from 1/4 to 1/16

I used this but in a two stage carving. It worked very well in the roughing stage and then followed by a 60° v-bit for the rest of the details. I highly recommend.

While this long shank might get you a deeper cut in some places, the 1/8 cutting portion is only 1 inch long, widens right out. So dont expect to get deep into corners/along sides because youve only got a 1 inch cut depth before the shank hits the upper wall of the material, prevents you from going deeper on the edge.
