How We Selected the Best Angle Grinder Under £50
We focused on published motor power, build quality from owner reviews, and the reliability of the brand. For cordless models, the battery ecosystem is critical as it affects long-term cost. We avoided any models with consistent complaints about spindle lock failure or excessive vibration. Every pick here has a solid average rating of 4.0 stars or higher from verified buyers.
What to Check Before Buying an Angle Grinder
First, decide between corded and cordless. Corded models offer unlimited runtime and more torque for the money, while cordless provides portability. Check the disc size: 115mm is standard for DIY, but 125mm offers more cutting depth. Look for a two-position side handle and a spindle lock for easy disc changes. Safety features like a paddle switch and anti-restart protection are also important, especially for beginners.
Mistakes to Avoid
Do not buy a grinder with a proprietary battery system that has few tools available. Avoid the cheapest no-name brands as they often have poor build quality and no warranty support. Never use a grinder without a guard, even for small jobs. Also, do not ignore the weight: a heavy grinder will cause fatigue quickly. Always check that the side handle can be mounted on both sides for different cutting angles.
Einhell TE-AG 18/115 Li
Best Overall CordlessPros
- Excellent Power X-Change battery system
- Lightweight and well balanced
- Soft grip handle reduces vibration
Cons
- Battery and charger sold separately
- Guard adjustment can be stiff
The Einhell TE-AG 18/115 Li is the best angle grinder under £50 for anyone already in the Power X-Change ecosystem. It offers a no-load speed of 8,500 RPM, which is sufficient for cutting metal and grinding welds. Owner reviews highlight its comfortable grip and low vibration, making it suitable for extended use.
The main drawback is that it is sold as a bare tool, so you need an existing Einhell battery. However, the ecosystem is one of the largest in the budget category, covering over 200 tools. The spindle lock is robust and the paddle switch design is intuitive. For the price, it is hard to beat for cordless flexibility.
Bosch Professional GWS 660
Best Corded PowerPros
- High 11,000 RPM for fast cutting
- Compact and lightweight design
- Bosch build quality and reliability
Cons
- Short power cable (2m)
- No variable speed control
The Bosch Professional GWS 660 is a classic corded grinder that delivers consistent power for cutting and grinding. Its 660W motor spins at 11,000 RPM, which is faster than many budget competitors. Owner reviews consistently praise its smooth operation and low vibration, even after years of use.
The main limitation is the 2-metre cable, which may require an extension lead for larger jobs. It also lacks variable speed, but for metalwork, the fixed speed is fine. The slim body makes it easy to hold for long periods. For a corded option under £50, this is the most reliable choice from a professional brand.
Ryobi R18AG-0
Best for Ryobi UsersPros
- Compatible with all Ryobi ONE+ batteries
- LED work light for visibility
- Tool-free guard adjustment
Cons
- Heavier than some competitors
- Battery drains quickly under load
The Ryobi R18AG-0 is a solid cordless grinder for anyone invested in the Ryobi ONE+ system. It features an LED light and a tool-free guard, which are rare at this price. Owner reviews note that it handles most DIY tasks well, from cutting rebar to grinding rust.
It is slightly heavier than the Einhell at 2.0kg, and the 8,000 RPM speed is adequate but not class-leading. The battery life is moderate, so having a spare 4Ah battery is recommended. For Ryobi users, this is the logical choice for a budget grinder.
Draper Storm 750W
Best Budget CordedPros
- High 750W motor for the price
- Includes grinding and cutting discs
- Two-position side handle
Cons
- Build quality feels less premium
- Vibration can be higher than Bosch
The Draper Storm 750W is the most powerful corded option on this list for the money. It spins at 11,000 RPM and comes with a set of discs, making it a great value starter kit. Owner reviews are positive for occasional DIY use, such as cutting bolts or sharpening tools.
The build quality is not as refined as the Bosch, and some users report higher vibration levels during prolonged use. The plastic housing feels durable enough for home use. For the lowest possible price, this is a capable performer.
Sealey CP1202
Best Compact DesignPros
- Very lightweight at 1.5kg
- Compact for tight spaces
- Good for light trimming and polishing
Cons
- 12V battery limits power for heavy grinding
- Battery and charger sold separately
The Sealey CP1202 is the lightest grinder on this list, making it ideal for overhead work or detailed tasks. It uses a 12V battery system, which keeps the weight down to just 1.5kg. Owner reviews appreciate its small size for getting into awkward spots.
It is not suitable for heavy grinding due to the lower voltage, but it excels at light cutting, polishing, and removing rust. The Sealey brand has a good reputation for workshop tools. For users who prioritise portability and comfort, this is a unique option.
FAQs
Can I use a 125mm disc on a 115mm grinder?
No, it is not safe. The guard will not cover the larger disc, and the motor may not handle the extra load.
What is the best angle grinder under £50 for cutting metal?
The Bosch Professional GWS 660 is best for cutting metal due to its high 11,000 RPM speed and reliable motor.
Is a cordless or corded grinder better under £50?
Corded models offer more power and unlimited runtime, while cordless provides portability. Choose based on your need for mobility.
Do I need a variable speed grinder?
Variable speed is useful for polishing or working on softer materials, but for general metal cutting and grinding, fixed speed is fine.
How long does a battery last on a cordless grinder?
With a 4Ah battery, expect 10-15 minutes of continuous heavy use. Light cutting can last up to 30 minutes.
Can I use a grinder for wood carving?
Yes, with a specific wood carving disc, but it is not recommended for beginners due to kickback risk.

No, it only works with Einhell Power X-Change batteries. It is not compatible with other brands.
