Nice Starter pack CNC Bit set

I have used these bit’s quite a lot especially the end mills and have had no issues, they’re still sharp and cutting well, nice set of bits for the price

Gilbert Odie

Very good set of bits


I have bought the down cut but before and it worked great. Lasted a good amount of time. So this time I ordered this four pack. The v bit and the taper bit look great. But the up cut and down cut. Are not flat on the bottom. I think the upcut will be fine but Im not sure about the down cut. I think they might head up when plunging into my work pieces on my CNC.


I've carved quite a few signs with these now, primarily using the thinnest bit. It still seems nice and sharp and cuts well.

Exactly what we needed
