Buyers Guide Questions

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 its being used.

These grinders are used for both cutting through material and for grinding, for instance, to smooth out the rough edges on masonry. When choosing this tool for projects, consumers will typically choose the right tool based on the disc size or motor, but other factors can include pneumatic or electric power source, rpm, and arbor size.

Operating a grinder safely becomes a number one issue, and there are a number of risks involved that need to be taken seriously, especially for first-time users or non-professional users.

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 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 is 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 kick back.
  • Keep sparks away from flammable objects.
  • Always secure the work piece.
  • 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 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. You can also use high quality Metal Cut Saw for cutting so, read our review and find out more.

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 beat 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 tuck pointing 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.

Can You Use An Angle Grinder To Cut Metal?

As a versatile tool, angle grinders are made for cutting rebar, tile and stucco, routing out mortar, and for polishing, cleaning, sanding, and sharpening. But when it comes to cutting metal, here is where this versatile little tool really shines.

When working with metal, there are many different kinds of wheels (or discs) you can use, based on the type of work you’re doing. But for actually cutting through metal, you will need to use a cut-off wheel. These wheels are basically a very thin version of the grinding wheel, made specifically to cut through metal, pipe, sheet metal, plate, and even through dimensional steel.

How To Remove An Angle Grinder Disc?

An angle grinder disc can be removed in just a few short minutes, with a little-bit of know-how. There are a few different ways to do this, depending on preference and tools at hand.

First: Turn of the power. Always make sure that your grinder’s power is completely shut off before trying to remove a disc. For a corded tool, unplug the cord from the wall outlet. For a cordless tool, remove the battery from the tool – this will also lighten the tool and make it much easier to handle as you change the disc.

How to Remove the disc with Spanners?

If your grinder includes two factory spanners that look like flattened wrenches – one resembles a normal wrench and the other looks more like a two-pronged fork – then you can use these to easily remove your discs. Insert the prongs in the two holes that are in the drive bolt, located between the disc and the tool’s motor.

Then, use the wrench-like spanner to secure the bolt on the bottom of the disc. While holding the wrench spanner in place, turn the pronged spanner in the opposite direction of the disc arrow. Note that there also may be a button on your grinder that holds the disc in place. Rotate the nut until the disc is removed from the tool.

How to Remove the disc with vice Grips?

Securely attach the vice grips to the bolt thats holding the disc to the drive. With the vice grips in place to keep the disc from spinning, insert a screwdriver into one of the holes between the disc and the motor. Pull the screwdriver in the opposite direction of the disc arrow. If it does not loosen right away, a hammer can be used to force the screwdriver to turn.

How to Remove the disc Without Tools?

With the palm of your hand, strike the disc in the opposite direction of the disc arrow. This action should loosen up the nut enough to remove it with your fingers.

Can Angle Grinder Be Used As A Polisher?

Angle grinders are a versatile tool that can be used for a myriad of projects, including cutting and grinding metal, cleaning tools, cutting and scoring, tile, stone or concrete, clearing out mortar for tuck pointing, and believe it or not, it also works great for smoothing and polishing.

To polish metal, use a polishing wheel or a buffing pad to restore the material back to its original luster. If it is really marked up, use a high grit grinding disc to smooth it out first. There are also many polishing compounds on the market made just for these grinders that will remove scratches and prepare the material for polishing up to a bright mirror finish.

How To Use Angle Grinder Safely?

Operating an angle grinder safely becomes a number one issue, and there are a number of risks involved that need to be taken seriously, especially for first-time users or non-professional users. The safety features included in this Black & Decker BDEG400 tool are an S-Automatic safety Slip Clutch that prevents kickback from a wheel or disc jam, that boosts safety.

The electronic overload protection built in with this tool prevents the grinder from becoming overheated during extended and more demanding work by shutting off power to the motor in the event of overload, or if the rotation speed suddenly drops. This protection serves to reduce the risk of motor burnout and controller failure.

When using this tool, please remember to always follow safety precautions, such as: Always wear a face shield and gloves, unplug the tool when switching wheels, position the work so the debris flies downward, and the wheel spins away from, not into, sharp edges, always secure the piece you are working on, and most of all, keep everyone away from your project while you are working.

Other safety tips to make your work environment safe, include decluttering your workspace – make sure that the floor where you’re working is free from scattered tools, timber, and power cables that could cause trips and falls. Proper lighting and adequate ventilation is also paramount to safe operation in your workshop. And finally, remove all flammable materials, including paper and oily cloths. Make sure you have a fire extinguisher on hand in the event a fire should erupt.

Some tasks are better off handled with different tools. For example for cutting bigger objects, you may want to look into, and invest, in a high quality electric chainsaw.
