Review on General Tools 841038 8 Inch Accessory by Chad Judex

Only cost me $7 and definitely not worth a dime when it's that much. Luckily I already have a good set of bit grips, otherwise I would be rather dissatisfied. The drill bit isn't of very high quality, of course, but it drilled holes well enough. The pens are fine. I've used all of them and haven't had any problems. Haven't tried centering pins yet, but I expect they will be fine too. So apart from the collar, which is pretty important, everything is fine. I wouldn't buy it again. You'll be happier buying better quality items separately for a few bucks more.
