Overview

The Milwaukee 2866-20 is an 18 volt battery powered drill built with a compact footprint, weighing 2.5 pounds and measuring about 9 inches long. It carries a 4.6 star rating from roughly 1,400 buyers and 100 recent purchases.

At 4,500 RPM and 2.5 pounds, this drill is sized for one handed use in tight spots rather than heavy demolition work. The 18 volt platform points to Milwaukee's cordless system, though whether a battery and charger ship with it isn't confirmed by the data here.

  • 18 volt battery powered platform
  • 4,500 RPM top speed
  • 2.5 pound compact build
  • 4.6 star rating, about 1,400 ratings

Who it's for

Tradespeople and serious DIYers already on an 18 volt battery platform who want a lightweight drill for daily use. Less suited to someone who needs a complete kit with charger and battery included, since that isn't confirmed here.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Compact 9 inch length for tight spaces
  • Light at 2.5 pounds for extended use
  • High 4,500 RPM speed for driving
What to check first
  • Battery and charger inclusion not confirmed
  • No description on file to verify accessories

Performance notes

The 4,500 RPM top speed suggests this drill is geared more toward driving and general drilling than high torque tasks like boring large holes in dense hardwood. At 2.5 pounds and about 9 inches long, it favors maneuverability in overhead or confined work over raw mass.
