What are the best angle grinders?

What are the best angle grinders?/An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing? Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.

Angle grinders can be powered by an electric motor, petrol engine, or compressed air. The motor drives a geared head at a right-angle on which is mounted an abrasive disc or a thinner cut-off disc, either of which can be replaced when worn. Angle grinders typically have an adjustable guard and a side-handle for two-handed operation. Certain angle grinders, depending on their speed range, can be used as sanders, employing a sanding disc with a backing pad or disc. The backing system is typically made of hard plastic, phenolic resin, or medium-hard rubber depending on the amount of flexibility desired.

To those of you who might not familiar with Angle Grinders before, according to Wikipedia, an angle grinder is a tool that is mostly used to polish, cut, grind, or sand materials. Sometimes, this tool is called “disc grinder” or “side grinder”. Since it is handheld, it is easy to learn and use even you are new to the tool.

Be Safe – Reducing Harmfulness While Using Angle Grinder

Although it is easy to learn and easy to use, be aware that this tool should never be in touch with children. It can also be harmful to adults and professionals if used without proper care. Here are some tips on how you can reduce harmfulness while using it:

  • Lowest Speed – If you are new to an angle grinder, you are recommended to set the lowest speed as possible. If there is any harm happens, at least it can reduce the risk.
  • Wear Proper Goggle – During the operation, there will be dust created in the environment. It is advisable that you were safety goggle correctly.
  • Wear Proper Mask – Like stated below, there will be dust. So it is a smart idea that you cover your nose and mouse with a dust mask to prevent yourself from any unpredictable circumstances.
  • Ask Expert – Angle grinder is not a toy for anyone to play around with. If you are not clearly sure what to do with the tools, ask your nearest expert to explain the whole process. It is always good to learn things from an expert rather than figuring it out by yourself and still being unclear.

What is the use of Grinding Machine?

A grinding machine, otherwise known as an angle grinder or side or disc grinders, is a commonly used tool in auto repair shops, workshops, and construction sites, and comes in a large variety of sizes and motor power. Designed for cutting metal and stone, the blades (cutting discs) vary according to the material on which it’s being used.

Angle grinders are categorized by their disc size (from 4 to 12 inches), wheel size, and amperage. For most DIY projects, discs that are 4 to 4.5 inches will suffice for general tasks. When operating this tool, please follow these safety precautions:

  • Wear a face shield and safe work gloves.
  • Unplug the grinder when switching wheels.
  • Make sure the handle is attached, and maintain a firm grip.
  • Use the guard, if possible.
  • For new wheels, run the unit for a minute or so in a protected area before using them to ensure there are no defects.
  • Position the work so the debris flies downward, and the wheel spins away from, not into, sharp edges. Wheels can catch onto an edge and cause the object to throw, or kickback.
  • Keep sparks away from flammable objects.
  • Always secure the workpiece.
  • Keep everyone away from your project while working.

What Can You Do With An Angle Grinder?

The cool thing about angle grinders is how versatile they are. There are many different sizes, but most tasks can be completed with the popular 4-inch to 4 1/2-inch grinder. These tools are made for grinding metal, cutting rebar, tile and stucco, routing out the mortar, for polishing, sanding, and sharpening and is an invaluable tool for any workshop, service garage, auto repair shop, or home hobbyist. Although there are some safety risks involved with using this tool, many models are designed to ensure optimum safety while delivering on performance. Here are a few main purposes of a grinder

  • Cleaning – Angle grinders make a great tool for cleaning caked-on cement and rust from tools by attaching a wire cup. Make sure the brush is spinning away from the edge of the tool, or you could experience kick-back.
  • Cutting Rebar – To cut through tough rebar in concrete, attach a metal cutoff wheel, and make sure your tool is secured tightly. Drop the cutoff wheel right through the metal allowing the weight of the tool to control the drop. Using angle grinders rather than hacksaws are much quicker and easier, making this versatile tool hard to beat.
  • Scoring Tile – Using a diamond blade, you can score right through the middle of a tile – for instance, to cut a hole for an outlet – by first marking the outline of the size of the hole, then securing the tile down to your workbench with a clamp. Score about 1/8 inch deep on the front of the tile with your grinder, which is a much easier job than with a tile cutter.
  • Sharpening Blades – For sharpening your other tools, an angle grinder can’t be beaten for its ease of use and power. Secure the blade in a vise or with hand clamps, then position the tool and adjust the blade guard to avert the sparks from your face and body. Then, align the grinding wheel with the angle on the blade, start the grinder and move the wheel across the blade while applying light pressure.
  • Grinding out mortar – With a tuckpointing wheel, you can easily grind out old, loose mortar by making two-three 1/2-inch deep drills to completely clear out the joint, keeping about 1/8-inch away from the brick.

Grinder Safety

Unlike drill motors that run at about 700 to 1,200 rpm, grinders spin at a breakneck speed of 10,000 to 11,000 rpm. They’re fast enough to be scary! Follow these precautions for safe grinder use:

  • Wear a face shield and gloves.
  • Unplug the grinder when you’re changing wheels.
  • Attach the handle and maintain a firm grip with both hands.
  • Use the guard if possible.
  • Run new wheels for one minute in a protected area before using them to make sure the wheel isn’t defective.
  • Orient the work so debris is directed downward.
  • Keep bystanders away. Everyone in the vicinity should wear safety glasses.
  • Orient the work so the wheel spins away from, not into, sharp edges. Wheels, especially wire wheels, can catch on an edge and throw the workpiece or cause the grinder to kick back (Photo 1).
  • Keep sparks away from flammable materials.
  • Clamp or secure the workpiece in some fashion.
  • Store angle grinders out of children’s reach.
