Overview

Weighing about 1.54 kilograms, the Vessel 400ER3-1M impact tool logged 100 purchases in the past month and holds a 4.5 star rating from 217 reviews.

Vessel is a Japanese tool maker known mainly for impact drivers and screwdrivers, and the 400ER3-1M's weight, close to 3.4 pounds, puts it toward the heavier end of that lineup rather than a compact bit driver. No manufacturer description is attached, so drive size, torque output and power source are not confirmed on this listing.
