  • Work well
Style: 5 PCS
These bits work well, they did not last as long as the much more expensive bits but in the long run the worked and I saved money on my projects, I use birch plywood so it has some harder wood in some of the ply's

  • Great Bit for CNC shopbot

Great Drill bit. I used for CNC Shopbot and it worked great.

  • It's good
Style: 1 PC
The down cut spiral router bit leaves a nice clean top edge. I'm using it in a handheld plunge router with a circle jig to cut holes and recesses in DIY speaker boxes. I don't really have anything else to compare it to but it seems to be sharp, decent quality and cuts smooth. I cannot comment on how long it stays sharp because I've only used it a few times. ... show more

  • Great for my CNC
Style: 1 PC
I bought this to use on my CNC machine for making flags and signs. It cuts very well and continues to do so after many cuts. The price is great and the quality is even better.

These are great bits. They hold their edge well after hours of use.

  • These are great bits for the money.
Style: 5 PCS
I've bought several sets of these CNC bits. We do a lot of profile cutting on a shop bot buddy. They cut cleanly and last quite a long time. And they're much more affordable than the name brand bits. I haven't had one break or prematurely wear out for reasons other than user error. Measure twice, cut once! ... show more
