Best cheap tool you ever bought.

I got an old drill grinder from work, for free when they shut down the machine shop

like this a darex (just looked it up, wow...$$$)

so I buy all the drill bits at yard sales
you can tell the good old steel bits right away, and I toss the junk
it will do up to a 1 - 1/2" bit and down to 1/8 (with a magnifier...lol)
I've always sharpened drill bits freehand. Constantly sharpening in batches, as we were always riveting something & needed to. Also bits up to the 1-1/2 to 2" range for the machine shop, using a 2 foot diameter disc sander, some multiple angles. Have a sharpening machine I inherited & kept & used little. Might need it now, since I don't see as well.
Need cataract surgery & trying to get fully moved beforehand.
Nice machine!
