dynamites metric hex driver set is a good choice for what is a must have for any pit box.The set includes 1.5,2,2.5mm heat treated high speed steel shanks inserted and secured with a small set screw into red annodized handles.the handles are anodized red with knurling for a better grip.I have had these for 3yrs now and not 1 broken tip or failure to date,and i use them almost daily.the part number is dyn2904 and retails for $19.99
