ASIN: B0D9H1MLF7Model: TMS00203-AUCategory: Drills
Overview
At just 1.8 pounds and 4 volts, the TMS00203-AU from the brand Electric is built for light fastening rather than heavy drilling.
The 4 volt supply and 280 RPM speed are well below what a typical cordless drill runs, which points to this being a light-duty or precision tool rather than something meant for boring holes in wood or masonry. At 1.8 pounds it is built for one-handed use over extended periods rather than heavy torque work.
- 4 volt battery
- 280 RPM speed
- 1.8 lb weight
Who it's for
Light assembly or small fastening jobs are the right fit, where low torque and a light body matter more than drilling power. It is not a match for anyone expecting to drill into wood, metal or masonry, given the low voltage and speed.
Pros and cons
- Light 1.8 lb body
- Battery powered, no cord needed
- Low 4V power limits torque
- Not suited to drilling hard material
Performance notes
A 4 volt battery and 280 RPM speed sit well under standard cordless drill output, which limits this to light fastening rather than drilling into dense material.
