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

i took no more than 1/8 of material at a time but it broke on the second pass. i am never buying from these folks again.

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

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.

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

Work great cutting 1 inch wood on my cnc

Works great but gets dull fast

this bit has worked very well so fare

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

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.

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
