This is one of many die grinder clones that use more or less the same design. This right angle design is ideal for everything from surface prep to cylinder head drilling and weld grinding. It is in every store and is distinguished by the quality of the components. Having not used this air tool in over a month, I am sticking with the star until I ditched it for about a year. This design doesn't have a fuse like most other straight grinders, but I personally hate the spring fuses, which are the most common, so I don't really care. One issue I have with the coffee grinder is that it uses way more air than 4cfm or whatever the packaging says. Think more of 6-8 cfm so either use a big 240v compressor or take breaks and let your small compressor catch up. Other grinders I've used are the same, so don't be surprised.
