Overview
A quarter inch collet holds the bit on this EMAX straight shaft die grinder, which runs on compressed air through a quarter inch NPT inlet. A lock-off trigger and rear exhaust are the features named in the highlight line.
The tool covers a broad list of jobs, from grinding and shaping to sanding, polishing and deburring, in a compact body. The limitation is what is left out: it is a bare tool with no warranty or accessories listed.
Who it's for
People who own an air compressor and fittings and want a compact grinder for metal finishing will use the tool as listed. Anyone needing a kit with bits and a warranty should look at a package.
Pros and cons
- Broad uses listed
- Bare tool only
- No warranty listed
- Needs an air compressor
Performance notes
Speed and torque come from the air motor, and the listed air requirement shows what the compressor must supply for it to hold its speed under load. Rear exhaust moves the outflow behind the user's hand. The collet size sets which bit shanks it can hold.
