To completely eliminate the possibility of making any mistakes when you make a purchase, it is essential that you look into certain specs and features.
| Spec/Feature |
How It Helps |
| Grinding Wheel Size |
It shows what is the power offered by the motor and for what type of jobs it is intended. Common grinder wheel sizes range from 4.5 inches to 9 inches, the smaller diameter wheels being best suited for small jobs, while bigger diameter wheels are intended for larger jobs. Thus, to make the right purchase, take into consideration the type of projects you need to use it for. |
| Motor – Amperage and Power |
Each of these power tools features a different type of motor, thus offering certain amp and power ratings. What you will most likely come across in terms of amperage is a range from 4 to 15, while when it comes to motor output power rating, it generally ranges from 500 to 2500 watts. Lower ratings indicate the tool should be used for small projects around the house, while higher ratings show it can be used in big projects at auto garages, construction sites, and so on. |
| Revolutions per Minute Rating |
The revolutions per minute or RPM rating indicates how powerful the tool is, and obviously, for what type of projects you can use it. Higher RPM ratings indicate you are dealing with a powerful and reliable tool for heavy-duty use on large projects, while lower ratings show that it is better suited for household use. Just be aware of the fact that higher revolutions per minute increase the risk of injury when the tool is not used correctly as well, so extra caution is recommended. We advise you to make your choice in terms of RPM rating depending on the use you intend for it. |
| Compact Design |
Obviously, the design it boasts directly affects how convenient it is to use and how comfortably you handle it. Considering you will most likely use it often, it is important to take comfort in use into consideration. A smaller and more compact tool translates to ease of use for long periods of time, a desirable trait especially for those who work in construction or auto garages as they are reliant on the tool most of the day. |
| Vibration Output |
Just like the design of the power tool, the vibration output it delivers is important as it shows how comfortable it feels during use. Also, it is a good indicator of how long you will be able to use it without feeling your hands get tired. The lower the vibration output the better, so we recommend you take this aspect seriously into consideration if you know you need to use the power tool for long periods on a regular basis. |
- The most common use of the tool is sanding or grinding away excess or unwanted metal or stone. An often encounter in construction sites, workers need the tool to make notches or cuts. You most likely need the power tool to perform these tasks, but there are other uses for it as well, as you will find out immediately.
- Aside from the common and obvious tasks you will use it for, it can be used to sharpen gardening tools and other tools you use around the house. Secure the blades to the work table by tightly clamping them for no unpleasant incidents to occur, and you can proceed to sharpen tools like axes, shovels, hatches, the blades of the lawnmower, and so on.
- Another surprising use is removing mortar. If you attach a diamond tuck-pointing wheel to it, you can remove old, loose mortar with it, all without risking damage being done to the brick. Strenuous labor is avoided this way as you will not be dependent on using the hammer or chisel anymore.
