Die, straight and bench grinders compared

A die grinder spins small mounted points and burrs in a 6 mm collet at very high speed for deburring, porting and finishing inside cavities. A straight grinder drives a larger wheel for grinding, polishing and de-rusting on castings and fabrications. A bench grinder sits on the bench for sharpening tools and dressing small parts. Always use points and wheels rated for at least the machine's no-load speed.
