  • These bits are excellent
Size: 1/8" Dia - 1" CL Style: DOWN CUT
These bits last a long time if used properly. I measured mine with calipers and found that they are actually .122-.123 in cutting diameter. So I set up Vectric to use that diameter and Ive had no issues with them.

  • CNC router bit.
Size: 1/4" Dia - 1" CL Style: DOWN CUT
Messed up any cut 5/8 pine with one pass and didn't break the bit. Seams to be a pretty good bit.

  • These are great bits for the money.
Size: 1/4" Dia - 1" CL Style: DOWN CUT
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
