Screwing/pluging goes a lot faster with a crew.
The one part systems do not work for me near as well as four separate operations. forstner bit, predrill, gule in plug, sand.
The OP systems clog up too fast, get dull too fast,don't provide a clean hole for the plug.
Buy the right size plug for the job,fastening South American lumber requires a sharp forstner bit plan on having a few on hand carbide tips are not worth the money, sand the plug right after install,fill the hole with the plug right away. Do not dwell in one place when sanding the plug down with the orbital feather it out.
With my Crew of three pluging goes faster than the clips, costs less money/time, is a great up sale, and looks really good. This is along with the given all my people have been doing this for a number of years.
In addition the clips are not " hidden " at all when you look down you still see the clip and the screw.
