DeWalt DWE402
Best OverallPros
- Powerful 11-amp motor for heavy cuts
- Durable all-metal gear case
- Low vibration design
Cons
- No variable speed
- Spindle lock can wear over time
The DeWalt DWE402 is a corded angle grinder that delivers 11 amps of power and 11,000 RPM, making it one of the strongest in its class. It features a narrow grip zone for better control and a two-position side handle for comfort. Owner reviews consistently praise its ability to handle thick metal without bogging down.
While it lacks variable speed, the fixed high RPM is ideal for cutting and grinding. The dust-sealed switch helps prolong motor life. For anyone who needs reliable, sustained power, this is the top choice.
Makita XAG17Z
Best Cordless PowerPros
- Brushless motor for longer runtime
- Compact and lightweight

Cons
- Battery and charger sold separately
- Higher price point
The Makita XAG17Z is a brushless 18V cordless grinder that provides near-corded power. It has a slim body for access in tight spaces and a variable speed dial (3,000 to 8,500 RPM) for different materials. Users report long battery life with a 5.0 Ah battery, making it suitable for all-day use.
It is part of the extensive Makita 18V LXT platform, so it works with over 300 tools. The main drawback is the cost, especially if you are not already in the Makita ecosystem. For cordless performance, it is hard to beat.
Bosch 1375A

The Bosch 1375A is a compact 6-amp corded grinder that is perfect for light to medium tasks like cutting bolts or sharpening tools. It weighs just 4.5 pounds, reducing fatigue during extended use. Owner reviews highlight its reliability and value for the price.
It is not meant for heavy-duty metal removal, but for the casual user, it offers enough performance. The slim barrel grip is comfortable. For a budget corded option, this Bosch is a solid investment.
Milwaukee 2780-20
Best Battery LifePros

It includes a flexible battery system that works with all M18 tools. The main downside is the high cost for the bare tool. For those who need long cordless sessions, this is the best option.
Ryobi P423
Best Budget CordlessPros
- Great value for the Ryobi system
- Accepts all Ryobi 18V batteries
- Good for light to medium tasks
Cons
- Brushed motor less efficient
- Not for heavy professional use
The Ryobi P423 is an affordable cordless grinder for the Ryobi 18V ONE+ system. It runs at 8,500 RPM and is suitable for cutting rebar, grinding small welds, or sharpening. Owner reviews note it is a great entry-level cordless option.
It is not as powerful as brushless models, but for the price, it offers solid performance. The battery compatibility with over 300 Ryobi tools is a major plus. For DIYers on a budget, this is the best cordless value.
What to check before buying an angle grinder
Power is the most critical factor. Corded grinders typically range from 6 to 15 amps, with 10 amps or more recommended for heavy metalwork. Cordless models depend on voltage (18V or 20V max) and brushless motors for efficiency. Wheel size is also key: 4-1/2 inch is the most common and versatile, while 6 inch or 7 inch models are for larger cuts. Safety features like a paddle switch, anti-kickback, and a spindle lock are essential. Finally, consider the brand ecosystem if you already own batteries from DeWalt, Makita, Milwaukee, or Ryobi.
Mistakes to avoid
One common mistake is buying a grinder with too little power for the intended job, leading to stalling and frustration. Another is ignoring the battery system: a bare tool is only useful if you have compatible batteries. Do not overlook safety: always use a guard and wear eye protection. Finally, avoid cheap no-name brands that lack replacement parts or reliable warranties.
