Makita GA4530R
Best OverallPros
- Superb build quality for the price
- Compact and lightweight design
- Labyrinth construction protects motor from dust
Cons
- No soft start feature
- Spindle lock can be stiff initially
The Makita GA4530R is a classic workhorse that consistently receives high praise from owners for its durability. It delivers 720W of power through a 115mm disc, which is sufficient for cutting metal, tiles, and grinding welds. The labyrinth construction seals the motor and bearings from debris, a feature usually found on more expensive models.
Aggregated reviews highlight its reliability over years of use. While it lacks a soft start or anti-vibration handle, its ergonomic grip and manageable weight make it comfortable for extended tasks. It is the safest bet for anyone wanting a no-nonsense, corded grinder that will last.
Bosch GWS 750-100 S
Best for CuttingPros
- Slim grip for better control
- Soft start prevents kickback
- Restart protection for safety
Cons
- 100mm disc limits depth of cut
- Slightly less torque than 115mm models
The Bosch GWS 750-100 S is designed for precision cutting with a 100mm disc. The 750W motor spins at 11,500 RPM, making it very fast for cutting metal or tiles. The slimline housing is a standout feature, allowing a comfortable grip even for users with smaller hands.
User reviews frequently mention the soft start and restart protection as key safety advantages. The main trade-off is the smaller disc size, which reduces cutting depth compared to 115mm grinders. For jobs requiring fine control and safety, this Bosch is a top contender.
DeWalt DWE4117
Best for Heavy DutyPros
- High 800W motor for tough materials
- One-touch guard adjustment
- Durable epoxy-coated field
Cons
- Heavier than competitors
- Vibration levels are average
The DeWalt DWE4117 is built for heavy grinding tasks. Its 800W motor provides the highest power in this roundup, making it ideal for removing thick welds or cutting through rebar. The one-touch guard adjustment is a convenient feature that speeds up job changes.
Owner reviews note that it feels very solid and handles sustained use well. The trade-off is weight; at 2.1 kg, it is noticeably heavier than the Makita or Bosch. This makes it less suitable for overhead work but excellent for bench or floor-level tasks where power is the priority.
Einhell TE-AG 18/115 Li
Best Cordless BudgetPros
- Very affordable entry to cordless
- Lightweight and portable
- Part of the Power X-Change system
Cons
- Lower RPM than corded models
- Battery and charger sold separately
The Einhell TE-AG 18/115 Li is a bare tool that offers cordless convenience at a low price. It runs on the popular Power X-Change battery platform, which is shared with many other Einhell tools. Its lightweight design makes it perfect for quick jobs and working in tight spaces.
Owner feedback indicates it is good for light to medium tasks like cutting bolts or grinding small areas. The 8,500 RPM is lower than corded grinders, so it struggles with heavy continuous use. For DIYers who already own Einhell batteries, this is the most cost-effective cordless option.
Ryobi R18AG-0
Best Cordless PowerPros
- Stronger brushless motor option
- Ergonomic grip with anti-vibration
- Compatible with Ryobi 18V range
Cons
- Battery life is limited under load
- Higher price than Einhell
The Ryobi R18AG-0 is a cordless grinder that offers better performance than many budget cordless models. It features a brushless motor that provides more power and runtime compared to the Einhell. The anti-vibration side handle and ergonomic body make it comfortable to use for longer periods.
User reviews praise its power for a cordless tool, noting it can handle most DIY grinding and cutting tasks. The main limitation is battery life; a 4Ah battery will last for moderate use but drains quickly under heavy grinding. It is the best choice for users already invested in the Ryobi ONE+ system.
What to Check Before Buying an Angle Grinder Under £100
Choosing the right angle grinder involves more than just looking at the price tag. You need to consider the power source, motor type, and safety features to ensure the tool matches your tasks.
Power Source: Corded grinders offer unlimited runtime and consistent power, making them ideal for heavy tasks. Cordless grinders offer portability but have limited battery life and less sustained power.
Motor Power: For corded models, look for at least 700W for general DIY use. Higher wattage means more torque for grinding and cutting thicker materials.
Disc Size: 115mm is the most common size for general purpose work. 100mm discs are lighter and better for precision cutting, but offer less depth.
Safety Features: Soft start reduces kickback on startup. Restart protection prevents the grinder from starting unexpectedly after a power cut. These are valuable safety additions.
Mistakes to Avoid
Buying the cheapest model: Very cheap grinders often have weak motors and poor build quality, leading to failure under load. Stick to reputable brands like Makita, Bosch, or DeWalt.
Ignoring disc size: A 100mm grinder is not suitable for cutting through thick steel pipes. Match the disc size to your typical work material.
Forgetting about accessories: Ensure replacement discs and accessories are readily available and affordable for the brand you choose.
Overlooking ergonomics: A heavy grinder can cause fatigue. If you have multiple tasks, consider the weight and grip comfort.
