Overview
The KJE Right Angle Die Grinder is an air powered grinder that spins at 25,000 RPM, built with a right angle head for tight space access. It falls under Amazon's Tools > Grinders category.
Being air powered, it needs a compressor and hose rather than a battery or cord, which is worth checking before buying if you do not already run compressed air tools. The right angle head is what sets it apart from a straight die grinder, putting the spinning bit at 90 degrees to the body.

Who it's for
