4 ½ Angle Grinder Buying Guide
Angle grinders are tools used to cut, grind and polish different materials by rotating an abrasive wheel. These tools come in five sizes such as 4 ½ inches, 5 inches, 6 inches, 7 inches, and 9 inches.
A 4 ½ inch angle grinder is the best size, as it is too easy to handle. You can use it for various home DIY projects. As the best size of an angle grinder, 4 ½ inch angle grinders dominate the market.
The designs of these angle grinders are pretty the same. So, what to look for before buying a 4 ½ Inch angle grinder from these extensive choices?
Read on the following buying consideration to find the perfect one for your projects:
a. Power Source
The power source should be the first consideration for a power tool. The angle grinder can be corded, cordless, or even pneumatic, depending on the power sources. Pneumatic ones use an air compressor to operate.
Cordless angle grinders are primarily battery-powered. These are very convenient and hence quite pricey. However, cordless ones are best to reach tight spots. These are portable, so you can carry them when power outlets are unavailable.
On the other hand, corded angle grinders are the most potent option. It requires a power source that restricts your range of motion. But in return, it gives the power to handle heavy-duty jobs.
So, What is Good for You, Corded, or Cordless?
Definitely, for a 4 ½ angle grinder, cordless models are the best choice. The power of a cordless grinder is compatible with this wheel size. Also, the cordless one is easy to handle because it is absolutely lightweight.
If you prefer versatility and portability, you should opt for a cordless model. But, cordless models require an extra battery which adds costs. Besides, these are heavier due to the added weight of the batteries.
Cordless models cannot handle high power output like corded counterparts. If your project requires much power, you should go for a corded angle grinder as it can be used for an extended period.
b. Fixed or Variable Speed?
The speed of angle grinders is measured in rotation per minute (rpm). Most 4 ½ inch angle grinders operate at 10,000 rpm or 11,000 rpm.
Fixed speed is never a good option for a powerful grinder. It doesn’t allow to change the speed limit according to the job. Alternatively, variable speed allows selecting between different speed ranges.
You can change the RPMs of angle grinders for comfortable maneuver. A few angle grinders in the market come with variable speed. Those can be used to run slowly for buffing or polishing purposes.
c. Disc Guard
When the disc rotates, it generates sparks and dust. Here a disc guard comes in handy. The position of the disc guard is easily adjustable. You can change its position to protect yourself from sparks and dust during work.
d. Disc Type
The discs of angle grinders are what serve different purposes. Hence, it comes in many types ranging from cutting discs, grinding discs, wire discs, and flap discs. Cutting discs are the thinnest among all and used for cutting metals.
Grinding discs are 5mm thick and used to smoothen rough surfaces. Then, wire discs are used to remove paints and polish different metals. Lastly, flap discs are sandpaper-coated and are utilized to smooth coarse surfaces; choose accordingly.
Wattage indicates the angle grinder’s power level. A high wattage doesn’t necessarily mean that it’ll be faster. This also does not mean that the grinder can withstand heavy use, excessive friction, and other abuse.
f. Check Arbor Size
The arbor denotes the shaft on which the disc is mounted. It also determines which type of discs will be compatible with the grinder. The standard arbor size of a 4 ½ angle grinder is 3/8″ -24. It means 3/8″ diameter and 24 threads in each inch.
g. Does It Make Loud Noise?
Angle grinders tend to create noise while cutting or polishing through the metals. That’s because it causes friction. So Not worry if it makes some sound. It will make noise when you are grinding, cutting, or polishing. There is no way to prevent it.
h. Avoid Slow Start
Most angle grinders run at speeds of 10,000 rpm, though. But you don’t want that speed level to kick it when you start the tool. It is not suitable for the motor itself. A slow start feature prevents it from reaching speeds of 10,000 rpm right away.
An ergonomic tool fits comfortably in the human hand. You may think every powerful tool is ergonomic and designed to fit the human hand. But in reality, some tools cause too much stress on hands, arms, shoulders, and back.
An ergonomic angle grinder will be more comfortable to use. This will not likely cause long-term stress injuries like inflammation. Also, the ergonomic tool is lightweight and well-balanced. It is easier to control and ensures well-finished results.
j. Other Features
A featured 4.5-inch grinder will also come with additional features for ease of use and safety:
- Quick change wheel release allows changing the disc rapidly and conveniently,
- Dust sealed feature that funnels dust away from the tool,
- Special hand guard to protect your hands from sparks or splinters,
- Safety features like vibration control, auto-brushoff, anti-kickback, etc.
1. Can I Use a 4-Inch Blade on a 4 1/2 Angle Grinder?
Yes! You can do that as long as the 4-inch blade is compatible with the 4 ½ angle grinder arbor. A 4-inch blade mostly fits into the arbor of a 4 ½ angle grinder. However, make sure the disc is rated to withstand the speed of the 4 ½ angle grinder.
You can generally use a small disc on a more giant grinder without worrying about crushing the disc. But a larger disc tends to change its shape when used on a smaller sized grinder. Using a 5-inch disc on a 4 ½ angle grinder will eventually become a 4-inch, then 3 ½.
2. What is the Best 4 1/2 Inch Angle Grinder under $100?
DEWALT DWE402K is one of the best that comes under $100. It is the most convenient grinder available in the market. Also, the power is up to the mark. Then, Makita 9557PBX1 Angle Grinder is another one on the list.
3. What are the Safety Considerations When Using an Angle Grinder?
It is not safe to use an angle grinder without using protective equipment. Always wear safety goggles, masks, helmets, ear protection, leather apron, and gloves. Also, make sure all this equipment is in a good state when you use it.
A 4 ½ inch disc size is the most favored for an angle grinder among DIYers. These are compact and are not exceptionally heavy. Most 4 ½ inch angle grinders are 12-inch long, which can get into tight spaces. Moreover, a 4 ½ angle grinder includes a maximum cut of about 2 ½ inches.
Admittedly, finding the best 4.5” angle grinder from the available options is tough. Luckily, you don’t need to check a bunch of angle grinders anymore. We have added 10 high-performing angle grinders.
We believe that DEWALT DWE402K would be the best choice for you. You can use it at home, in an auto shop, or construction site. If it doesn’t suit your budget, check more options.
