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

Sometimes you need to cut thicker wood. This bit helps with that task. I don’t know about the longevity yet.

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

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.

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

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

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

Liked the length , able to cut 3/4 material with several passes. The 1/4 inch shaft is far better than using adapters that somtimes slip
