A buddy of mine wants me to cut some drain holes in a tractor tire that he uses in his workouts. I decided I would accomplish this by getting a metal hole saw bit (1" or so) and make a bunch of holes with my impact drill. So, the last time I was at Lowe's I went to grab a few, figuring that the rubber would dull them pretty quickly so I would need more than one. Well, all the ones they had were for chucks bigger than my drill which is 1/4". I have little need for hole saw bits so I don't use them but what do these fit into? I thought all the impact drills were 1/4". Also, where would I find what I need in 1/4"? Thanks.
.....I may just scrap the drill altogether and make a bigger mess than expected.
