All four are professional-grade, but they serve slightly different priorities. Milwaukee M18 FUEL has the broadest tool selection (375+ tools) and dominates the trade market, especially for electricians and plumbers. DeWALT 20V MAX is the most common platform on framing and GC crews and has the FLEXVOLT 60V system for heavy-duty work. Bosch is strongest in concrete and SDS rotary hammers. Makita LXT is favored by woodworkers and finish carpenters. For most Houston contractors starting from scratch, Milwaukee M18 has the deepest ecosystem.

Impact drivers use a ¼" hex collet and deliver high-frequency rotational impacts at moderate torque (typically 1,800–2,000 in-lb) — they're built for driving screws and small bolts. Impact wrenches use a ½" (or ¾"/1") square anvil and deliver much higher torque (700–1,800+ ft-lb) with slower, harder impacts — built for breaking loose lug nuts, large bolts, and structural fasteners. Most contractors carry both: a compact impact driver for daily fastening and a mid-torque impact wrench for heavy work.

Yes, for daily use. Brushless motors run cooler, last roughly 50% longer per charge, and have a 3-4x longer tool lifespan than brushed motors because there are no brushes to wear out. The price premium has dropped significantly — most pro-grade tools (Milwaukee FUEL, DeWALT XR, Makita LXT brushless) are now brushless across the board. For occasional use, brushed tools still make sense; for daily contractor work, brushless pays back fast.
