Overview
Weighing just 170 grams, the GrenPRO-071904 is a small cordless drill running on a 4V battery at 220 RPM. Its size and power point to light precision tasks rather than general construction drilling.
170 grams and 220 RPM put this closer to a handheld precision screwdriver than a jobsite drill, useful for its portability but limited in torque and speed compared to standard drills.
- 4 volt battery power source
- 220 RPM speed
- 170 gram tool weight
- Compact precision-driver format
Who it's for
Hobbyists and anyone doing small electronics, eyewear or craft repairs who wants an ultra-light cordless driver. Not suited to drilling through wood, metal or masonry.
Pros and cons
- Very light at 170 grams
- Cordless 4V battery power
- Easy one-handed control for small tasks
- Low voltage and RPM limit it to light-duty use
Performance notes
At 4V and 220 RPM, the GrenPRO-071904 has limited torque and speed, and its 170 gram weight keeps it easy to control one-handed on small work. That combination favors precision fastening over any drilling task requiring real power.
