Milwaukee 2953-20

I ran the Milwaukee Gen 4 vs DeWalt DCF860 the way you’d actually abuse an impact on a tough day—50 lags, then 1.5″ spade-bit holes until things got spicy. One driver hit 264°F, literally sizzled, and still pushed to 100 holes. The other stayed cooler, but started shutting down and came up short. Here’s what really happened—and what I’d buy.
