Overview
The 21V CHD-120-Y is a cordless drill built around a 21 volt, 4000 milliamp-hour battery, spinning up to 2150 RPM. At 13 by 10 by 8 inches, it's sized like a standard drill and driver kit rather than a compact model.
Battery specs here point to a mid-size cordless driver: 21 volts is common for consumer-grade drills, and the 4000 mAh cell should support a reasonable number of holes or screws per charge, though runtime depends on the bit and material. Its 2150 RPM top speed sits below other cordless drills, suggesting a driving-oriented tool rather than one tuned for fast hole-boring.
- Battery powered, 21 volts
- 4000 mAh battery capacity
- 2150 RPM top speed
- 13" L x 10" W x 8" H
Who it's for
Cordless-first users doing driving and drilling around the house or job site without staying tethered to an outlet. Less suited to anyone chasing maximum RPM for fast drilling.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cordless with a sizable 4000 mAh, 21V battery
- No cord to manage on the job
- 2150 RPM is modest next to faster corded options
- Battery needs charging between sessions
Performance notes
The 4000 mAh capacity at 21 volts gives the battery a reasonable energy budget for driving screws and drilling smaller holes between charges. A 2150 RPM top speed is moderate, so it should handle everyday fastening without being the fastest option for boring larger holes quickly.
