Charleston Plumbing Nightmare Defeated

Locked in an 1800s crawlspace, my elbow jammed against brick while drilling joist penetrations for cast-iron replacements. Standard drills simply wouldn't fit. The DEWALT DCD740C1 changed everything - its 2.4" head and 90° power cleared 28 holes in 19 minutes, torque twisting through century-old heart pine without binding. When walls close in like a vise, this isn't just a drill: it's your mechanical contortionist.

The Unfiltered Verdict

Where Milwaukee's right-angle binds in oak and Bosch struggles with stainless, DeWalt's U-drive warrior laughs at 6" cavities while drilling like a full-sized rig. As the Charleston plumber watching me exit the crawlspace muttered: "That tool head's thinner than my wrench – and twice as mean."
