Very happy with these interchangeable piloted counterbores! They met my needs perfectly, as I needed to counterbore some aluminum extrusions for through-bolts. Easy to set up, sharp bits with tons of configuration flexibility. Now that I have the option to counterbore things, I’m just looking for more reasons to!These come in a decent little carrying/organizer case with everything you need for great quality, accurate counterbores.
