Overview
Not an angle grinder, this AOBEN tool is a slim pencil-style die grinder that spins small burrs and abrasives in line with the body. A corded motor drives it, and two wrenches are included for changing the collet.
A narrow body reaches into recesses where a larger grinder cannot go, and high free speed suits small bits for fine metal and plastic work. Collet size, motor power and tool weight are not listed, so check them before buying accessories.
Who it's for
A metalworker, model builder or auto hobbyist handles edges and recesses with small burrs and sanding drums. Buyers who need cutoff wheels or large flap discs should look at an angle grinder instead.
Pros and cons
- Slim pencil shape for tight spots
- High maximum speed
- Corded power for long jobs
- Two wrenches included
- Collet size not listed
- Motor wattage unspecified
Performance notes
Die grinders depend on speed, so small burrs and abrasive points do their best work at the high end of the range, and larger bits need slower, lighter passes. A straight body aligns the bit with the wrist, which gives control for shaping and deburring. Bit choice, not the tool, determines whether the job is grinding, polishing or cleaning.
