"Good case made of steel and plastic looks as though it should survive a drop (not tried). Has magnets on base that will hold the case and contents to a vertical steel surface but it may not take much to dislodge it. The magnetic bit holder is longer than the usual and slightly thicker with an outer sleeve you can grip. Bits are slotted,3,4,5,6 and 7mm, T10, T15, T20, T25, and T30 and two sets of PH1, PH2 and PH3. No posidrive bits. Drill bits as listed. My reservation is that the range of sizes is limited so you may well find the one you need is not there."
