Clean and Strip XT Disc, 4-1/2 in x 5/8 in-11, Extra Coarse, Silicon Carbide, 13300 rpm, Purple

I've used this disc in restoring vintage a American made vises that I restore and sell. It easily removes old paint, and really anything that happens to be in the surface of the vise. I will remove most of the paint with a wire wheel, and then finish up with this. It also does a great job on the “slide”... the part of the vise that covers the screw and guides the moveable jaw through the body of the vise. It will even out and shine up the surface without being too aggressive, not gouging or removing much metal at all.

Wow wow wow. I really don't use strip discs very often because they typically just turn to bits of flying strip disc the first time they touch metal and just do a mediocre job. I used this to clean about a total of 25' of 2.5" square tubing and maybe 10' of other similarly sized steel. I still have pad left and removing mill scale has never been easier. I didn't damage the base metal, so even thin gauge material stays whole, but the scale just flies off with one, maybe two quick passes. The fact that it's a threaded center is just icing on the cake for me, but this thing lasts a shockingly long time, does the job incredibly well and keeps my clumsy self from gouging the base metal like I would with a flap disc or anything else. I'm going to order a whole bunch of these and stop using my flap discs for weld prep. It's rare that a new product comes along that changes my process or habit.
