Plugs come out poor - with cordless drill
I wish I could post a photo here. I've done about 20 plugs in cherry, using blanks between 3/4 and 7/8" thick. I've gone as slowly as I can, but 90% of them come out broken or the edges are very rough and uneven. I've tried cross-grain and with-grain; same result.
-Spoke to tech support. Rep said to switch from my 18V Makita to a corded drill. Solved the problem. System works well with the corded drill.
-Another update. I was using my B&D 4A drill; worked much better than the battery operated drill, but I still wasn't getting great results. Since the tech told me the issue was the need for high RPMs, easy feed rate and steady power, I upgraded to an 8A DeWalt corded drill running 0-2,500 RPM. Results are still better, but I really don't think they're good enough for furniture.
I've placed photos here: https://www.pinterest.com/emsennett/kreg/. In each photo, the best plug is on the top. I tossed all the cross-grain attempts - which were unusable - so everything you see is cut with the grain.
Kreg, I'm pretty dissatisfied with these results? Do you think I might have a bad bit? Other ideas?
