When the hole is bigger than the drill wants to make, this is the tool. Triple gear reduction takes the motor down to 0–600 RPM and converts that speed into torque — the lowest-geared drill in DeWalt's corded lineup, and the one that keeps pulling when a self-feed bit is halfway through a doubled joist.

That gearing is the whole point. It'll swing a 4" hole saw in wood, a 2-9/16" self-feed, or a 2-3/4" hole saw through steel — bit sizes that stall drills geared for speed. Triple reduction also spreads the load across more gear teeth, which is why the drivetrain lasts under abuse that eats lighter tools.

The gears themselves are helical-cut and heat-treated, running in a metal gear housing rather than plastic. That housing is what survives a drop off a scaffold plank and the general indignities of being the drill everyone on the crew borrows.

At this torque level the 360° side handle is required equipment, not a convenience. When a big bit grabs, the handle is what stops the tool from spinning in your hands — set it wherever the cut demands. The two-finger rubber trigger spreads pressure across your hand for the long, slow pulls that low-RPM work involves, and the 1/2" keyed chuck holds large shanks tighter than any keyless design under this kind of load. Chuck key and holder included.

Built for plumbers, electricians, and HVAC installers boring through framing — anyone whose holes are measured in inches rather than fractions.
