Preparing Your Work Space and Staying Space

A tool with a wheel rotating at intense speeds, it's vital that you learn how to use an angle grinder safely. Unlike a drill that can turn at 700 – 1200 times per minute, an angle grinder has a free speed that averages at 12,000 RPM. Thus, you have to practice safety at all times when using the tools. The common precautions include: 

  • Unplug the grinder when you want to change the disc or wheel
  • Ensure you attach the handles firmly to the grinder
  • Maintain a firm grip on the grinder at all times
  • If the grind comes with a guard – use it
  • When you get a new disc, run it in the grinder for a few seconds, to ensure all components are fully functional
  • Ensure that debris falls down and out the path of the grinder
  • Ensure the blade spins away from at all times
  • Keep track of issues such as sparks that might catch on combustible materials in your space

Remember, an angle grinder is a powerful tool that can release lots of sparks and dust. Thus, you need to prepare accordingly before you start using the tool. Ensure that your workspace is clean and that there is nothing that will catch fire as you use the tool.

Even more, dust might also collect around your workspace, thus ensuring that you remove all items that you don’t need in your workspace. When using angle grinders, ensure that you use sturdy gloves, protective boots, dust masks, goggles, and more.

Using an Angle Grinder

How to Cut Stone and Concrete Using An Angle Grinder

Tile cutters are ideal for making cuts across the surface of stone tiles or ceramic material. That said, you might find it difficult to produce accurate cuts that can you can install around obstacles such as power outlets. With an angle grinder, you can make quick work of such fiddly tasks. Here are the steps involved:

1. Marking up & clampdown

Using a pen, mark an outline for the cut on both the front and rear sections of the tile. Ensure that you are accurate with cuts because your accuracy determines the quality of the finish. Also, clamp the tile to a workbench, and ensure the front section faces up. Ensure the cutter sits stable, to avoid any injury which can occur if the tool slips when cutting. 

2. Score the Face

Turn on the machine, and score on the outline of the front section of the tile. Consider scoring around a 1/8 th of the surface

3. Complete the Cut

 Turn the tile over, and then place it on the clamp again. Ensure the back of the tile faces up, and cut through the tile from the back section. You can extend the cuts past the corners, to help produce excellent cut quality results.

4. How to Cut Metal Rods, Bolts and Bars

When you either want to cut material arduously with a hacksaw, or perhaps cut rough metal with an angle grinder, you have to use the correct technique. Simply put, you can't beat the results an angle grinder can provide for your projects. The steps involved in cutting metals rods or bars include:

5. Prop the bar

Move to step two, if you want to trim a bolt flush in durable materials such as concrete or metal. Ensure that you place the prop firmly on the long section of the bar, and ensure it locks to the structure. The shortest section of the bar should be the part that drops away. 

6. Producing the Cut

Turn on the angle grinder, and allow the disc to attain the proper speed. Then, drop the wheel through the metal and let the weight of the tool cut through the material. Only let the shot end to drop away from the metal rod.

How to Restore Cutting Edges and Sharpen Blades

An angle grinder can work perfectly for restoring various types of rough edges on your household tools with ease. These include tools such as shovels, hoes, axes, lawn mower blades, and more. You can always improve the finish by using a mill file once the process is complete. The steps involved include:

1.Clamp the Blade

The first step is to clamp down the given tool or blade by using a vice or a C-clamp to the workbench. Ensure that the grinder disc spins away from the user, to help safeguard you from any flying sparks. An arrow on the body of the grinder should show the direction in which the blade will spin. 

2. Align the Disc

You will have to align the angle grinders disc with the cutting edge of the blade that you are using. Start using the grind, and allow the disc to rotate at full speed. Also, ensure the disc moves steadily across the blade and apply a little amount of pressure. Move the grinder from the end of the handle, and up to the tip of the tool. Then, ensure you keep the grind in a stable position and move it up to the tip of the tool.
