Overview
The PSD S1 ACE is a cordless drill built around a 4 volt battery and a 250 RPM motor, closer in scale to a precision driver than a full size drill. At 5.76 ounces it is light enough for one handed use on delicate materials.
Voltage and RPM here sit well below a standard drill or driver, which points toward light assembly or craft work rather than boring holes in wood or metal. No torque figure is listed, so buyers comparing against full size cordless drills should treat these as different categories entirely.
- Battery powered
- 4 volt motor
- 250 RPM
- 5.76 ounce weight
Who it's for
Suited to small assembly jobs, model making, jewelry work or anywhere a full size drill would be too much tool. Anyone drilling into wood, metal or masonry on a regular basis needs a higher voltage machine than this one.
Pros and cons
- Very light at 5.76 ounces
- Battery powered, no cord to manage
- Sized for one handed detail work
- No torque or chuck size listed
- 250 RPM limits it to light tasks
Performance notes
The listed 250 RPM and 4 volt battery place this at the low power end of the cordless drill category. Weight is under 6 ounces, so fatigue during extended handheld use should be minimal, though the tradeoff is limited driving force. No torque, chuck size or runtime figures are published.
