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
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
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
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
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
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.
