Grinding and lapping Grinding and lapping An angle grinder is a handheld tool powered by an electric motor, petrol engine or compressed air. This drives a gearer head on which mounts an abrasive disc that can be renewed when worn. There are myriad different discs that are used for various materials and tasks, such as cutting discs, buffing pads and saws. The angle grinder has large bearings to counter side forces generated during cutting, unlike a power drill, where the force is axial. ...more on Wikipedia about "Angle grinder"

Emery paper is a type of paper that can be used for sanding down hard and rough surfaces. It can also be used for resistant technology purposes to give a smooth, shiny finish to manufactured products and is often used in the finishing of high-end watch movements. Similar to sandpaper, it is made by gluing small particles of the mineral emery (also called iron spinel or hercynite) to paper. ...more on Wikipedia about "Emery paper"
A flick-grinder is a rough and ready surface grinder or tool and cutter grinder, its usage is varied but it may be used where great accuracy is not required, but a machine better than a bench grinder is required. ...more on Wikipedia about "Flick grinder"

A grinding machine is a machine tool used for producing very fine finishes or making very light cuts, using an abrasive wheel as the cutting device. This wheel can be made up of various sizes and types of stones, diamonds or of inorganic materials. For machines used to reduce particle size in materials processing see grinding. ...more on Wikipedia about "Grinding machine"

Sandpaper is a form of paper where an abrasive material has been fixed to its surface; it is part of the " coated abrasives" family of abrasive products. It is used to remove small amounts of material from surfaces, either to make them smoother ( painting and wood finishing), to remove a layer of material (e.g. old paint), or sometimes to make the surface rougher (e.g. as a preparation to gluing). ...more on Wikipedia about "Sandpaper"
