We have several M12 tools that are really good for lighter duty tasks than our larger capacity battery powered Bosch or Milwaukee tools. Those tools are also MUCH larger!
This 2505-20 tool with attachments excels in tight spaces. This, first week we had the tool, it enabled secure installation of a small safe in a tight space which absolutely needed the offset drive accessory! Only thing missing is the hammer drill function in the 2504 M12 hammer drill, which also has a 1/2 in capacity chuck.
Pros:
+ solidly built, though compact for tight spaces
+ right angle and offset driver attachments are wonderful in really tight areas!
+ accepts all capacities of M12 Fuel battery packs
+ one of the few really useful magnetic tool carriers built in to a compact tool
+ 2520-22 kit is excellent deal where you can find it!
+ reverse/lock button is impossible to hit by accident, but see below
Cons:
- really wish there was a cutoff wheel attachment available too! instead of using drill chuck
- reverse/lock button isn't as handy as most, including other M12 tools, tradeoff for eliminating accidental reverse!
- an optional 1/2" chuck attachment would be welcome too!
- unable to fit the 2502-20 into a portable drill press stand which works with other M12 drills
All-in-all, the 2505-22 which includes the 2505-20 drill and two M12 2ah batteries is an excellent set to have whether or not you have a lot of tight spaces to work!
