Types Of Grinders
Automotive grinders are perfect for mechanics and auto body workshops. They can use these machines to remove rust, bolts, and nuts.
They are also used for polishing chrome, steel body parts, and engines.
Woodwork bench grinders are a suitable option for craftsmen that use sharp hand tools like chisels or planes.
They can help with making well fitted dovetail joints or smoothing rough wooden surfaces. However, sharpening these tools manually takes a lot longer.
Variable speed grinders
Variable speed grinders are a good fit for those who work in both auto body repair shops and woodworking applications.
Fast speeds are used for cleaning bolts and nuts while slower speeds are great for sharpening hand tools.
Portable speed grinders
Bench grinders are heavy and work well when table mounted. This also prevents the grinder from moving.
However, if you require a unit that can be taken to various worksites, the compact and small units with rubber feet are a more suitable option.
Features To Consider
The wheel material on the grinder is an essential aspect to consider. The most common materials include:
This is most commonly found on multi-functional grinders that can be used for various grinding applications.
These wheels can heat up rapidly which is not ideal when using superior quality hand tools like planes and chisels.
Wheels made from this material do not get heated fast and are suitable for grinding hard metals like alloy steel or carbon steel.
These are constructed with brass and steel bristles, making them perfect for cleaning away the gunk and grease found on auto fittings and valves.
Ceramic aluminum oxide
These wheels are primarily used for grinding away materials from hard steel and alloys.
These wheels are made from thick brushed materials and are used for polishing metal and steel to produce a high shine.
Wheel type & size
A bench grinder is characterized by the wheel size which is normally a diameter of six or eight inches. Both sizes work equally but come with different considerations.
Any power tool you buy will pose some risks, and bench grinders are no exception. Safety features that are useful on these power tools include:
Eye safety shields
These normally come standard with most bench grinders and help with keeping steel or metal shards away from your eyes while working. Eye shields are also replaceable.
These are tiny steel plates found between the eye shields and wheels. They are designed to prevent sparks from flying everywhere.
There will be sparks but these arrestors prevent it from going too far out.
Standard bench grinder accessories are engineered to make the operation of the tool easier and simpler, these accessories include:
- Tool rests – allows you to hold a blade or knife steady while you’re grinding
- LED light – illuminates your work area for better visibility
- Rubber feet – prevents portable grinders from sliding over the work area
- Water tray – this is useful for cooling off the items you’re working with
