like one reviewer state , this bag be more like a tool box than a tool bag . I have use mine to carry all sort of different gear and tool , quickly throw whatever I need for the job into the bag , hook on the shoulder strap , and head out the door . I work in a environment where I be able to have a permanent `` tool cage '' and similar rolling case to store my tool in the shop , but I often need to grab a few tool and head off to a job somewhere . this be where these bag come in . I fill they with whatever I need , and off i go . I know this sound like a task for any old bag , but these tough bag withstand the weight and beating of heavy use without flinching . I know one reviewer complain about not be able to stand up he drill , but if that be a concern to I , I would transport they in the original DeWalt hard plastic case . I be usually in such a hurry that I need something big and reliable to throw my stuff in but not so big that I can not move it . I also own one of the smaller version of this bag , the DeWalt d6050 -lrb- asin b0006jkusw -rrb- that I use for a permanent collection of basic hand tool I keep in it at all time . give the minimal price difference between the two , I could have opt for another d6100 , but the smaller model prevent I from overload it to the point where I would break before the bag ! this be a great bag for any on-the-go pro !
