Makita GA4530R
Best OverallPros
- Compact and lightweight design
- Durable aluminium gear housing
- Low vibration for comfortable use
Cons
- No soft start feature
- Spindle lock can be stiff initially
The Makita GA4530R is a staple in the angle grinder market, known for its compact 66mm grip diameter and robust 720W motor. Owner reviews consistently praise its reliability for cutting and grinding metal, with many reporting years of trouble-free use. The labyrinth construction protects the motor from dust and debris, extending its lifespan.
While it lacks a soft start mechanism, the GA4530R compensates with smooth operation and a side handle that offers three positions for better control. It is a solid choice for tradespeople and serious DIYers who want a dependable corded tool without spending extra on features they may not need.
DeWalt DCG412B
Best CordlessPros
- Brushless motor for longer runtime
- Compact and lightweight
- Compatible with DeWalt 18V system
Cons
- Battery and charger sold separately
- Not as powerful as corded models
The DeWalt DCG412B is a brushless cordless grinder that offers excellent portability for site work and remote jobs. Owner reviews highlight its long runtime on a single 5Ah battery, making it suitable for cutting rebar or grinding welds without being tethered to a power outlet. The tool-free guard adjustment is a welcome convenience.
It is a bare tool, so you need existing DeWalt 18V batteries to use it. While it lacks the raw torque of a corded grinder, the DCG412B delivers consistent power for most metalworking tasks and is a top pick for those already invested in the DeWalt ecosystem.
Bosch GWS 7-115
Best ValuePros
- Affordable price point
- Flat head design for tight spaces
- Safety switch prevents accidental start
Cons
- Vibration levels higher than premium models
- Plastic gear housing
The Bosch GWS 7-115 is a budget-friendly corded grinder that delivers reliable performance for light to medium tasks. Owner reviews note its flat head design allows for flush cutting in corners, making it useful for metalwork and tile cutting. The 720W motor handles most DIY jobs, from removing rust to cutting bolts.
It has a plastic gear housing, which keeps weight down but may not withstand heavy abuse as well as aluminium alternatives. For home users who need a capable grinder for occasional use, the GWS 7-115 offers strong value without breaking the budget.
Einhell TE-AG 115
Best BudgetPros
- High power for the price
- Includes grinding and cutting discs
- Adjustable guard without tools
Cons
- Heavier than competitors
- Build quality feels less premium
The Einhell TE-AG 115 offers a 750W motor at a very low price, making it an attractive option for budget-conscious DIYers. Owner reviews indicate it handles basic tasks like cutting metal and grinding mortar well, and it comes with a set of discs to get started. The tool-free guard adjustment is a practical feature at this price point.
It is heavier than the Makita or Bosch, which can cause fatigue during extended use. The plastic housing and lower overall build quality mean it may not last as long under heavy use, but for occasional projects, the TE-AG 115 provides excellent value.
Milwaukee M18 CAG115B
Best Heavy-Duty CordlessPros
- Powerful brushless motor
- Long warranty period
- Excellent dust protection
Cons
- Battery and charger sold separately
- Higher price within budget
The Milwaukee M18 CAG115B is a Fuel brushless grinder that delivers near-corded power in a cordless form. Owner reviews highlight its ability to handle heavy grinding and cutting tasks without bogging down, and the REDLINK intelligence system protects the tool from overload. It is a bare tool, so you need Milwaukee M18 batteries.
It is the most expensive option under £150, but the 5-year warranty and robust build make it a worthwhile investment for professionals. The tool is slightly heavier than the DeWalt, but the extra power and durability justify the weight for demanding applications.
What to Check Before Buying an Angle Grinder Under £150
When shopping for an angle grinder in this price range, focus on power, disc size, and ergonomics. Most models use 115mm discs, which are standard for cutting and grinding metal. A motor between 700W and 800W is sufficient for DIY and light trade work.
Check the weight and grip diameter. Lighter models reduce fatigue during extended use. Look for a side handle that can be mounted on either side for better control. Safety features like a two-finger trigger or paddle switch are important to prevent accidental starts.
Mistakes to Avoid When Choosing an Angle Grinder
One common mistake is buying a grinder with too little power for the intended tasks. A 500W model may struggle with cutting thick metal, leading to overheating and poor results. Stick to at least 700W for reliable performance.
Another mistake is ignoring the availability of spare parts and accessories. Brands like Makita and Bosch have wide support networks, while lesser-known brands may be harder to service. Also, avoid buying a cordless grinder without checking if you already have compatible batteries, as buying a new battery system can increase the total cost.
