Bosch PS21-2A Drill Review

Our scorecard

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.

Overview

The Bosch PS21-2A runs on a 12-volt battery platform and tops out at 1,300 RPM. At just 1.4 pounds, it is one of the lightest drills in the cordless category, a real advantage when holding the tool overhead or threading into awkward angles behind panels or inside cabinets.

Priced at $109.00, the PS21-2A sits above entry-level 12V options, reflecting the Bosch build quality that 2,400 reviewers and a 4.7-star average endorse. Demand is steady, with 200 units purchased last month. The 2-amp draw is modest, which is expected for the 12V platform, so battery runtimes per charge will depend on workload.

The low weight and compact form factor come with a natural limitation: the 12-volt platform produces less raw torque than 18V or 20V peers. For finish work, assembly tasks, and cabinet installation this is rarely a problem. For heavy-duty fastening through thick lumber or steel, a higher-voltage drill is the better fit.

Specifications

Performance notes

Battery powered at 12 volts, 2 amps, with a 1,300 RPM no-load speed. Weight is 1.4 pounds. The combination of sub-1.5-pound weight and 12V output makes this drill optimized for precision and comfort over raw power. Best suited to screw driving, finish assembly, and light boring rather than high-torque applications.

What buyers say

With 2,400 reviews and a 4.7-star average, owners consistently note the PS21-2A's comfort and balance during extended use. Feedback patterns suggest strong appreciation for the weight savings and handling in confined areas. A minority of owners note the battery capacity limits longer sessions without a spare.
