| This adapter is used in
adapting a 6-inch flat lap in a drill press for the use of grinding edges of
the beads or cabs you have cut out with the core drills. |
Adapter |
Bead |
Just to show what can be made with the
core drill and a diamond drill bit. |
The drill adaptor is used
to center the hole in the bead that you have drilled with a core drill. You
drill about 2/3 of the way though your slab with the core drill then insert the
drill adaptor into the groove and it will allow you to find the center
perfectly each and every time. Drill just enough to mark the hole then remove
the adaptor and finish drilling again only about 2/3 of the way though. After
you have started as many beads as you want from the slab finish the core drill
so you release the bead from the slab. Turn the bead over and use the adaptor
to find the center from the backside and then finish drilling until you meet
the hole from the other side. You have a perfect hole without any chipping
around the edge.
These come in 3 sizes. Custom
