What Can We Do With This Angle Grinder?

The angle grinder is a versatile tool used widely for grinding metal, routing out the mortar, cutting tile/rebar/stucco, polishing, sharpening and sanding. Although, it comes in different sizes but we use 4 – 4 ½ inch grinder to complete most of the tasks. It is a must-to have tool for any service garage, auto repair shop, workshop or home hobbyist.

There are some risks involved while using this tool but most of the modern models will ensure safety along with delivering performance. Now let’s know, for what purpose we use this grinder mostly.

  • Cleaning – A wire cup is attached to this power tool for cleaning caked on cement and rust from various tools. But be sure that to spin the brush away from the edges of tool or else you may experience kick back.
  • Cutting Rebar – Simply, attach a metal cutoff wheel to the angle grinder for cutting tough rebar in concrete, but make sure the tool is tightened securely. Drop this cutoff wheel after cutting through metal to reduce the weight of the tool. Angle grinders is much quicker and easier to use than hacksaws. Also, you can use a high-quality metal cutting saw to do this cutting.
  • Sharpening Blades – An angle grinder has its ease of use and power while sharpening other tools. Simply secure the blade in a vise and position the tool. Try to adjust the blade guard to prevent sparks and align the angle grinding wheel on the blade and start grinder. Apply slight pressure while moving the wheel across the blade to sharpen it.
  • Scoring Tile – One can easily score through the middle of a tile by using a diamond blade. For example, if you want to cut a hole in an outlet then you have to mark the outline of the hole size. Now secure the tile with a clamp to the workbench. Score about 1/8-inch deep on the front of tile with the grinder. It is much easier than using a tile cutter.
  • Grinding Out Mortar – The tuck pointing wheel of the angle grinder will allow you to grind out the old, loose mortar. Simply make 2 – 3 ½ inch deep drills to clear out the joint completely and keep 1/8-inch away from brick.

What we need to consider when Buying Angle Grinder?

Here we are providing some buying considerations that help you to choose the best angle grinder, which suits perfect for all your future projects.

1. Power Source:

Based on the power source, we can categorize this angle grinders into three different types – corded, cordless & pneumatic.

Although, most of the angle grinders are battery powered (cordless) but you can find corded (electric-powered) or compressed air powered options. So, you have to consider the power source before buying the grinder.

A. Cordless (OR) Battery – Powered:

  • A cordless grinder is handy tool for completing various onsite jobs.
  • The lithium-ion battery and modern brush less electric motors will make it last longer for a working in between recharges.
  • It has an easy access to tight spots but comes with a drawback of battery charging, as it may cause some pause to your work session for few hours to recharge again.
  • So, we always suggest you to carry an extra set of batteries while planning to use this cordless angle grinder, especially outside the workshop.
  • The latest models come with a quick-charge technology of at least 30 minutes to grab a decent charge for the drained 6 Ah battery.
  • It weighs at least 2 – 3 pounds more than small corded models.

B. Corded:

  • Are you looking for high power output for long lasting operation? Then simply go with corded angle grinder, where you won’t need to recharge or replace the battery.
  • Simply, you have to plug in the corded grinder into a standard power outlet to make it work efficiently.
  • The indefinite running time and consistent power are main advantages of this corded model.
  • They are lightweight and inexpensive when compared with cordless models.
  • Its drawback is that it has limitation of the work area, as one can work within the range of its outlet and also has slight risk of sawing into the power cord accidentally.

C. Pneumatic Angle Grinders:

  • It is a modern version of corded electric model, as it takes the corded model to a whole new level.
  • All you need is to plug the tool into a suitable air compressor unit to make it function properly.
  • It is the lightest and cheapest angle grinder than above two types, why because it runs without any electric motor or battery.
  • The air pressure will supply the power source to make it run effectively but make sure to check it properly before investing in this model.

2. Disc Type:

The angle grinders come with different types of discs or wheels, which includes wire discs, cutting discs, flap discs & grinding discs. However, each disc or wheel serves for different purposes, in which you have to interchange them regularly by depending upon the type of your welding job.

  • Grinding Discs are 5 mm or more thicker and thus used to smooth rough surfaces or clear slag.
  • Cutting Discs are thinnest among other discs and are widely used for cutting metals.
  • Flap Discs are coated with sandpaper, which makes it suitable for creating smooth surfaces.
  • Wire Discs help to clean the sensitive surfaces and thereby allows you to polish the metal surface without decaying metal. They remove the rust from metal and remove old paint from metal or wood surfaces with the paint stripping discs.

3. Disc Size:

The power and overall capacity will be indicated by the disc or wheel of the grinder. The larger discs are widely used for high volume work to produce a smooth finish in less time, and thus it indicates a more powerful tool. The small compact one is optimal for focus tasks or jobs, where it requires precision and having a lot of tight angles or small spaces. So, while selecting the disc size, one has to consider for what type of work, they are using this grinder.  Generally, we can see discs that comes within 4 – 9 inches in size.

  • For DIY projects / General tasks, we have to use the discs that comes with disc size of about 4 – 4.5 inches. The reason is that, they can be easily fitted into different surfaces, easy to use and lightweight.
  • For Industrial purposes, use angle grinders that uses disc size of 9 inches or larger, depending up on the type of surfaces.

4. Disc Speed in RPM:

How the grinder performs ultimately will be determined by its speed. An average grinder may have speed range of 5000 – 10,000 revolutions per minute. The faster the speed, the more it produces desired results. But you should handle the speed properly, which you will get through experience or else it may wind up damaging the whole workpiece.

So, to get relief from this problem, choose an angle grinder with variable speed settings. This speed setting will allow you to select various speed ranges to optimize the tool, as needed to complete your project. In case, if you don’t have access to this speed setting then simply choose the grinder with a speed range which you can handle easily.

The revolutions per minute (RPM) is also termed as no load speed, which means the fastest rotation a grinder makes without any disc installed. The smaller discs will handle faster RPM than large ones.

Verdict If you want to distinguish two angle grinders with same amp rating, then simply choose the one that comes with high RPM (as it provides most torque).

5. Motor Power:

Generally, the power of the grinder will be measured in terms of wattage (Watts, W). The input power in corded models is rated in terms of Amps (A). For cordless one, the input is specified in Volts (V). The input power for pneumatic models is termed as cubic feet per minute (CFM) with operating pressure in pounds per square inch (PSI).

In general, a higher wattage won’t mean the motor can able to stand up against excessive friction, heavy use, and other situational stress, in which a well-used power tools will incur the job. But the high amperage is used to perform heavy projects rather than counterparts with low power outputs.

Novices can try 7 – 8 amps initially and then upgrade to standard amps of 9 – 10. For heavy projects (like welding thick pipe) requires high wattage and large discs. The available voltage for corded angle grinder will be 110V, 240V whereas the rechargeable cordless models has 18V as best.

Verdict – When comparing two grinders with same RPM, then simply choose the one with high amp rating which have most torque. For instance, while comparing two grinders with same RPM of 1100 but different voltage like 7 amps and 12 amps then go with grinder that comes with 12 amps, which has more torque.

6. Weight:

The weight of the tool will decide its usability. The user won’t require a bulky angle grinder, especially for those who are using this tool for weekend projects. Also, remember a grinder which is light in weight will won’t last longer for usage over years. So, its always recommended to stick for an angle grinder that comes with a weight range of 3 – 10 pounds.

7. Safety Features to Consider:

Welding is a high-risk activity, especially if you won’t follow safety measures. So, one should follow adequate safety -enhancing measures like wearing safety goggles and gloves while handing these grinders. Grinder with heavy weight will come with increased risk of injuries, as they are more than your handling capacity. Its recommended to check out some items like safety guards, disc brake, locking system and switches before buying an angle grinder.

  • Adjustable Disc Guard – Generally, the disc guard protect the user from sparks and other debris which may fly-off while working on a work piece. This adjustable disc guard will let you change the disc guard position in a convenient way to protect yourself from sparks and debris.
  • Disc Brake – To slow down or stop the disc, we need a brake that operated in trigger/paddle. It is an essential safety feature and without a brake, the disc will spin till gravity stops it. The angle grinders will run at high speeds and without any trigger/paddle to control will make it dangerous. So, a disc brake will protect you from any injuries.
  • Locking Functionality – The lock on/lock off feature will let the user to lock and unlock the paddle in place without having to depress the paddle to control the grinder’s movement. Designed specially for those who has constant use of this grinder. This will lock the paddle when the grinder is not in use and thereby increases safety.
  • Dust Sealed – Grinders will produce a lot of dust while operating and without this dust sealed, the dust may find their way into inner working parts and destroy motor and thereby tool. So, its essential to have special dust protection like a seal or a unique pattern to clear away the dust from the device (especially from electrical inner workings).
  • Hand Guard – To protect the user’s hands from sparks and splinters, some models are specially designed with hand guards. Also, one can find adjustable hand guards to alter the grinder that suits all your needs of your project.
  • Spindle Lock – One can easily and quickly change the disc with a button to prevent the spindle from turning. This lock will helpful whenever the disc retaining nut is tightened or unscrewed.
  • Vacuum Attachment – We came to know that grinders will create a lot of dust while it is used. So, manufacturers designed a few models with vacuum attachment. This will allow you to connect the grinder to a vacuum and thereby reduce the dust in the workplace.
  • Movable Side Handle – A movable side handle will allow grinder to operate either with left or right-handed. This option will allow you to work in different positions with this grinder to complete your task.
  • Anti-Vibration Handle – This will allow the grinder to use comfortable over extended periods. This will reduce fatigue, improves control and maneuverability.
  • Type of Switch – Always pay attention while choosing grinders that are based on the switch types. The paddle switches will turn on by the fingers that makes it ideal to use for welders. Usage of slide up switches will be appropriate if you want to turn off the grinder with ease.

8. Other Disc Attachments:

Here are a few other forms of disc attachments which are used for operating angle grinder in various tasks. Have a look on it.

  • Silicon Carbide Discs – Used to grind down welding, clean sheet metal, around the edges of steel pipes, sharpen metal tools and shape the metal.
  • Cutoff Disc – Designed specially to cut harder stuff such as bolts, rods, metal pipes and rebars.
  • Sanding Pads – Used to clear old paint as surface preparation step and used for coarse and fine sanding.
  • Grinding Discs – Suits best for sharpening garden tools and shaping their edges quickly.
  • Wire Brush Wheels – Used widely to strip off pain and rust along with clearing off the burrs from rough-cut metal surfaces.
  • Diamond Cutting Blades – Used to cut concrete, masonry, tile or granite. These diamond blades are designed for both dry cutting and wet cutting.
  • Aluminum Oxide Wheels – This versatile disc is used for wood working and cutting crumbly materials such as particle boards.
  • Flap Disc – It works similar to wire brush but comes with flaps rather than wires. Ideal for blending a weld bead into the rest of metal. It deburrs rough cuts and finish metal and used to remove the large amounts of wood, including sanding pad.

9. Price & Warranty:

Angle grinders are available in a wide range of prices. This comes relatively at an inexpensive price. So, choose the high quality and long-lasting angle grinder that suits perfect to deal effectively with your project. Also, look for the warranty (of at least a year) provided by the manufacturer to make an add-on to your purchase.
