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 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

this bit has worked very well so fare

Im an experienced woodworker, this bit is not worth the price. In fact the price implies that it is US or European made as the Amazon profile does not disclose it is China made. It broke within the first minute of use. Im sending it back for a refund. Amazon- disclose the country of origin on all products, quit playing games.

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.

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

Works great but gets dull fast

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.

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

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
