Angle grinders, also known as disc grinders or side grinders, are convenient and helpful tools to use for grinding, including abrasive cutting as well as polishing. Following is a detailed angle grinder comparison review: Makita vs. Dewalt vs. Bosch vs. Porter Cable vs. Hitachi.
1. Makita 9557PBX1 Angle Grinder
- Powerful 7.5 AMP motor for high output power in a more compact tool (only 4.5 pounds)
- Small diameter barrel grip (only 2 to 1/2 inches) for added comfort
- Labyrinth construction seals and protects the motor and bearings from dust and debris for longer tool life
- Lock on/off feature for continuous operation
- AC/DC switch for use with alternative power source
This angle grinder is made of plastic. It comes with a powerful 7.5-amp motor which helps to deliver 11,000 rpm, ensuring high output power.
Its labyrinth construction protects and seals its motor from the dirt and debris. This helps provide the tool longer life and durability. The heat and energy loss is reduced by the closely wounded thick coil.
It also includes a spindle lock for easy wheel changes, special lock-on feature, a side handle that can be installed on either side of the grinder and a wheel guard.
The best thing is that it also includes an extra diamond wheel and comes with an aluminum case which makes it easy to maintain and carry.
The Makita 9557PBX1 has a customer rating of 4.5 out of 5, which means it is quite satisfactory in use. The customers have rated it to be one of the best angle grinders out there as its paddle switch runs the entire length which makes it easy to hold from any point.
2. Dewalt DWE402 Angle Grinder
- Next Generation 11 Amp AC/DC 11,000 RPM motor of angle grinder provides the best power to weight/size ratio available
- Dust Ejection System provides durability by ejecting damaging dust and debris particles that enter the metal grinder
- Oversized brushes of this DEWALT angle grinder provide 2 times brush life over previous model (D28402)
- Large spiral bevel gear provides long transmission life
- One-Touch Guard allows for 360 degree rotation of the guard with a single action
This 4-1/2” angle grinder comes with an 11-amp motor giving out 11,000 rpm. It runs on both AC and DC power supply at 120V and is comparatively more powerful than the Makita angle grinder. It has oversized brushes and a large spiral bevel gear. Its exclusive Dust Ejection system protects it from dirt and debris.
This angle grinder includes the Quick-Change wheel release that provides for the freewheel removal without using a wrench. The top-mounted spindle lock button helps with a deep cut without compromising durability.
Its One-Touch Guard allows for 360-degree rotation at a single push, which is definitely a promising feature and makes the tool faster.
It has a 3-year manufacturer warranty. Also, the single Allen wrench that comes with the grinder is a simple solution instead of using two different wrenches to change the wheel/discs, as is the case with many angle grinders.
The Dewalt DWE402 is rated 4.6 on a scale of 5. Generally, the customers are really happy with the one-guard feature and the power, which is immediately noticeable. This model is the best out of all other Dewalt angle grinders as well as among other companies as it provides the best power to weight/size ratio (horsepower) available.
3. Bosch 1375A Angle Grinder
- Compact: Weighing only 3.75 pounds, the Bosch 1375A Angle Grinder is lightweight, compact, and ideal for metal workers, vehicle fabricators, plumbers and other professionals who use grinders on a daily basis
- Power: The angle grinder features a Powerful 6.0 amp motor to produce 11,000 no load rpm for professional cutting and grinding applications; The Efficient motor was designed with an extremely small field diameter, letting the user grind or cut with ease
- Comfort: The 1375A offers a 2 position side auxiliary handle specifically designed to angle to a natural position for maximum operator comfort; The top handle of the angle grinder is also ergonomically designed
- Convenient: The angle grinder also features Bosch’s Service Minder Brush System to eliminate guesswork and stops the tool when preventative maintenance is required; A 5/8 inches to 11 inch spindle works with a wide array of sizes, mounting the most popular accessories
- Durable: The 1375A angle grinder features an epoxy coated design to protect the tool from abrasive debris; It was also designed with a sealed switch to keep dust and debris from entering the switch mechanism
The Bosch 1375A is lighter than the Makita and Dewalt. Its 6-amp motor delivers 11,000 rpm and is equally as powerful as an 11-amp motor due to the slim housing grip designed for easy handling.
It comes with a dust-resistant switch to ensure protection and a two-position side handle to make it easy to hold from any position for maximum control and comfort. Its Service Minder brushes stop the grinder when preventative measures are needed to be taken. Moreover, it also includes a guard, a flange kit, a wrench, and a wheel.
Despite the lighter weight and high power, it is rated 4.4 out of 5, as there is a newer 7.9-amp model which promises to be more powerful. The customers have further complained about the guard, whose position is difficult to change and requires an Allen wrench to change it. Also, it has ribbed plastic switches that make them harder to move. Therefore, in my view, there are better angle grinders out there.
4. Porter Cable PC60TAG Angle Grinder
- 11,000 RPM angle grinder is designed for high speed material removal
- Durable 6-amp motor of metal grinder powers through jobsite tasks with ease
- Cast metal gear case increases jobsite durability and tool longevity of the hand grinder
- Tool-free change guard provides fast and easy guard removal
- Spindle lock feature allows for single wrench bit changes
The Porter Cable PC60TAG comes with a durable 6-amp motor that delivers 11,000 rpm. It includes the wheel, a wrench, tool-free guard, spindle locks and a 3-position side handle which allows greater control of the guard on different angles.
Its power cord has a good length of 6’ and is quite flexible but not very heavy (6 amps do not need a super heavy wire anyway). The fact that it does not allow variable speed makes it useful only for small tasks such as wood cutting.
It is rated 4 out of 5. The customers have wished for a power switch that would be easier to control and operate. Also, the handle needs to be padded or rubber-lined and not on the forward angle. This makes it come in the way for granite and ceramic cuts.
It does not come with a case, which makes it difficult to carry, and does not allow variable speed. Comparatively, there are better options available.
5. Hitachi G12SA3 Angle Grinder
- Hitachi Power Tools has renamed to Metabo HPT. Same great tools, with only a new name.
- 8 Amp motor, with Max output power of 1,900W for the toughest grinding jobs
- Tool rest, conveniently located to protect the switch from accidentally turning on and prolonging tool life
- Auto stop brushes, tool will shut off automatically to indicate brush wear is too low and avoid damage to the armature
- Hitachi Original Armature Coil Protection to protect from abrasive particles entering the motor to extend tool life
The Hitachi G12SA3 is a specially designed angle grinder that delivers a powerful 1900-watts output power. This makes it easier to grind through the hardest material with quiet comfort. It comes with an improved cooling mechanism which helps achieve the highest overload durability. This feature makes this tool the most efficient and highest in resistance as compared to the other angle grinders mentioned above.
The on/off switch is mounted on the top, which makes it equally helpful for the left and right-handed users. It allows for the side handle to be fixed at either right or on the left depending upon the user’s convenience.
The side handle is projected on 70 degrees rather than 90 so that it does not come in the way while using the stretcher for a longer time. It has a one-touch quick-off mechanism which ensures safety. Exclusively, it is designed to draw in the air from the rear side in order to prevent the air from being discharged from the front directly on the user’s face.
It is rated 4.6 on a scale of 5. The customers are, generally, very satisfied with the advanced and compact features of this tool.
It can be seen from the above discussion that each angle grinder has its own pros and cons. Overall, in a comparison of Makita vs. Dewalt vs. Bosch vs. Porter Cable vs. Hitachi, we recommended Makita 9557PBX1 and Dewalt DWE402.
