Milwaukee 49-22-4185 All Purpose Professional Ice Hardened Hole Saw Kit 28 Piece

As others have said, the case is pathetic. Overall its a good deal considering their individual price

These things rock but I had quite a time getting going. I needed to cut 4 holes in 1 3/4 inch depth of ply. A couple of notes 1) you cant tell from the pic but the bits are not 1/4 hex, they are 9/16 or some odd size..... good luck finding an adaptor to get these working with a regular 1/4 hex driver. First I tried a hex nut to make the connection but it was too wobbly. The Dewalt chuck adaptor for the 1/4 hex didnt work either (too small and it sucks) and there doesnt appear to be an adaptor for s4s max either....... hmmm, surely something I have out there will run these things...... finally I pulled out an old dewalt drill that had a big enough chuck to hold the bits and I was off to the races. 2) Do the chuck up tight! 3) Make sure you are holding the damn drill with both hands, nice and strong, things can get wild with the bigger hole cutters and they can lock up really suddenly if you shove too hard or drop sideways, giving the drill and your arm a good twist. I found that the drills cut a nice clean circle in laminate without chewing the edges, which was pleasing. Overall great tool.
