M.A. Ford – Countersink, Solid Carbide, 82 degree, Single Flute
These are the same countersinks we have been using in our shops for years. These are a solid carbide single flute countersink. It is true that they cost more than the cheap countersinks. But, we have found that they will create less chatter and last much longer than most of the other less expensive brands we have tried.
