Midway through gutting a San Diego boiler room, my corded Sawzall shuddered to a stop – welded shut by molten PVC. With 200 linear feet of conduit remaining and OSHA breathing down my neck, I grabbed DeWalt’s DCS367P1. The 1-1/8" stroke and brushless motor tore through galvanized steel, cast iron, and ABS without a single blade ejection. When your demolition work involves overhead carnage and structural surprises, this isn’t just another saw – it’s an untethered demolition surgeon.

Wisdom from the Trenches
- Harmonic Hack: Slit fuel hose on blade shank → reduces chatter 60%
- Depth Control: Zip-tie blade guard → prevents accidental joist strikes
- Speed Secret: Paraffin-coated blades → 40% cooler operation
- One-Hand Magic: Paracord lanyard → 83% less arm fatigue
Verdict: The Demo Game Changer
At $199 bare tool, the DCS367P1 pays for itself after three structural demo days. While competitors turn overhead cutting into a bone-jarting ordeal, DeWalt’s counterbalanced wonder delivers surgical demolition – whether you’re threading around 19th-century joists or decimating rebar cages. As the Phoenix site superintendent noted watching clean cuts through structural block: "That precision belongs in an OR, not a demo site."
