Choose the fastening job
Milwaukee 2746-20 adds brad fastening to an M18 kit used for drilling and cutting. It suits a carpenter who repeatedly moves between trim details without wanting to relocate an air hose. The manufacturer uses a sealed nitrogen mechanism with battery power. M18 FUEL is a product range name here, not a requirement to buy disposable fuel cartridges.
Controls and alternatives
Compare the contact nose, fitted battery and approach to the actual molding before treating the cordless body as a confined-space solution. Milwaukee documents tool-free depth adjustment, a jam-clearing latch and operating-mode selection. Those controls do not guarantee flush seating in every material. An owner liking the adjustment range is useful context, while another owner's fault report cannot establish a population failure rate.
Build the complete fixing kit
The -20 package omits batteries and charging. For an existing M18 user, it can avoid another platform; for a first kit, compare the complete cordless purchase with NT50AE2 plus a suitable existing air supply. Budget for the right 18-gauge brads and face protection. Larger 15-gauge trim fixings and 21-degree framing nails require different tools, regardless of battery compatibility.
