Best 4 1/2 Angle Grinder Grinder Power Tool

Bosch is a leading company combining technology to develop powerful tools that make work easier in industrial, energy, and building areas. Some of the products made by Bosch include range cookers, dryers, and grinders, among other appliances. We will review one of its products: the Bosch 1375A Corded Angle Grinder. You will love the metallic build and the design of this machine. Here are more of its features.  


The first thing you will notice about this angle grinder is its design. It is made of metal but only weighs 3.75 pounds, making it suitable for professionals who want to fabricate cars, work on metal, or for plumbers who want to cut metal pipes. In addition, its weight makes it easy to carry around from one workstation to another. 

Nothing can go wrong with this angle grinder. Through the Minder Brush System, the machine automatically stops any functions whenever any repair or maintenance is required. In addition, it has 5/8 inches to an 11-inch spindle that can fit well with other metal and woodwork accessories.

This grinder will give you years of impressive functionality thanks to its epoxy-coated body covering it from abrasive materials that can reduce its quality. In addition, it has a sealed switch that keeps dust and other foreign materials from entering the machine’s insides.

Professional metal workers will love the power output of this machine. Through its 6.0AMP motor, the grinder can produce 11,000 load RPM. This RPM makes it possible to cut through metal and other grinding tasks. In addition, thanks to the grinder’s small field meter, you can easily cut any wood or metal. 

Grinding is not easy, so having the right equipment is essential. The good thing with this piece of equipment is that it is easy to hold it thanks to the two-position handle, which provides the user with maximum comfort. In addition, the top handle is ergonomically designed, ensuring that you don’t become fatigued when working for long hours while still being able to cut the desired material with excellent precision. 

On the downside, some customers have found it challenging to assemble the grinder parts. A detailed user manual would help assemble the grinder in less time. 


  • Durable body can be used for all projects
  • Ergonomic design is easy to hold
  • High power output
  • Easily portable for on-the-go work


  • Hard to assemble the parts

2. Black + Decker 7750 Small Angle Grinder

Best 4 1/2 Angle Grinder Grinder Power Tool

The company’s focus is to help resolve the globe’s skilled trades shortage. A great example of equipment that will assist you in your day-to-day work is the Black + Decker 7750 Small Angle Grinder. This piece of equipment has a powerful motor that makes cutting metal easier. 


This angle grinder comes with a powerful motor that produces 10,000 RPM. The power output is enough for cutting metal pipes and fabricating, among other applications. 

In addition, you don’t have to worry about fatigue when working with this machine. The good news is that this piece of equipment has a two-position side handle that lets you hold the grinder with a solid grip ensuring you can cut metal with excellent precision. With the contoured body grip, you are also assured that no injuries can happen as the grip prevents the slipping of the machine. 

Moreover, this angle grinder comes with a two-year limited warranty. The good thing with this type of warranty is that you will not fully pay for any repair as you will share the repair cost with the manufacturer. 

Another good thing about this grinder is that it is cheap for what it has to offer. So this machine will work well within your budget if you want a grinder that can do an impressive job for home repairs.

On top of that, this piece of equipment has a metal gear shift. This ensures that the body does not wear out due to the tasks it can do. With the metal gear shift, you’re sure of an extended life of this grinder.  

However, this grinder is mainly meant to be used for light work and quickly wears out when used on metals like aluminum. 


  • Powerful motor for all projects
  • Convenient for home repairs
  • Two-year limited warranty
  • Cost-effective – great price for great quality


  • Not fit for heavy grinding work

3. Makita 9557PBX1 Angle Grinder

Best 4 1/2 Angle Grinder Grinder Power Tool

You cannot talk about the best tool brands without hearing the name Makita. This is because the company invests its resources in making the most resilient and innovative power tools you can find in the market today. An excellent example of a product made by Makita is the Makita 9557PBX1 angle grinder. This product has a lot to offer, from its powerful torque to its lock/off feature. 


It can take some time to grind or fabricate metal. The good news is that this machine has a lock-on or off feature that lets you continue to work as long as you need. So, you don’t have to keep on pressing the ‘ON’ button while you can take advantage of the lock-on feature. 

You don’t have to worry about the grip with this machine. It has a small diameter barrel grip that makes it convenient for many users. The barrel grip’s size is about 2 ½ inches, so you don’t have to worry about the machine slipping from your hand. 

Moreover, this angle grinder has labyrinth construction. The good thing about such a structure is that it protects the electric parts of the grinder from dust and other foreign materials that can damage it. In addition, zig-zag varnishing on the grinder’s body protects the machine from dust and wear. This protection extends the product life of the appliance. 

The AC/DC switch ensures you can work with the machine wherever you go. For example, a client might call you to work on some metal and you find that the area uses an AC power supply. The good news is that you can switch to AC and begin your work with just the press of a button.  

Nevertheless, this product is not free from flaws. For example, although the grinder comes with a tool case, the case needs to be bigger to fit the grinder with its accessories. Another problem with the grinder is that it overheats after using it continuously for some time. Therefore, you should watch the time the machine stays on as it can destroy the grinder’s internal parts. 


  • Comes with AC/DC switch for different power sources
  • Sturdy build for many years of use
  • Good grip is easy to hold
  • Lock-on feature for continuous operation


  • Overheats after continued usage
