Overview
The Hi-Tech 21-003 is a corded electric tool running on 115 volts at 3400 RPM, weighing 13 pounds with an 11 by 11 by 15 inch footprint. It holds a 4.5 star rating from 253 reviews.
The category label here is simply Specialties, and with no description text to draw on, the footprint and weight point to a countertop or bench mounted unit rather than a handheld tool. Confirm the specific function on the product listing itself, since the available data covers electrical and physical specs but not what the tool does.

Who it's for

Performance notes
At 115 volts and 3400 RPM, the motor runs at standard US household voltage, and the 13 pound weight combined with an 11 by 11 by 15 inch footprint suggests a unit meant to sit on a bench rather than travel to a job.
