I've owned a 1/2" Milwaukee "Magnum hole shooter" drill for about 30 years. It still works great, but it's usefulness is limited by its size, etc. It does not have a brake, so the heavy chuck is impossible to stop quickly, which means that it really is inappropriate for driving small screws, especially sheet metal screws. I'm looking at cordless options. (I already own a corded hammer drill, so I do not need a hammer drill.)
Ideally, I'd like to buy one do-it-all tool. I now realize the advantages of impact drivers versus drill/drivers when it comes to drilling rather large holes or, especially, driving large screws. But when it comes to driving small fasteners such as small-ish sheet metal screws, when I don't want the fastener to turn literally one extra turn when the bottom of the screw head hits the metal, the drill/driver with its adjustable torque ring seems to be the right tool for the job.
Apparently up to this point 1/4" hex impact drivers have not had anything like the torque-adjustable ring that drill/drivers do. However, now there is the so-called 1-Key Milwaukee impact driver and, supposedly, the torque is adjustable. But how adjustable is it? Can this tool drive sheet metal screws without turning the screw one extra turn after the bottom of the head hits the metal? If the answer is "yes", then that will be my do-it-all tool.
While I'm typing, does Milwaukee intend to instroduce a 12V Fuel impact driver with the 1-key, adjustable-torque feature? Does any other manufacturer produce an impact driver that has an adjustable torque similar to that of the typical drill/driver?
Thanks.
