Below is a quick comparison of our top picks tested for the UK market:
| Model | Type | Disc Size | Best For | Key Standout Feature |
| DeWalt DCG405N | Cordless (18V) | 125mm | Heavy-duty DIY & Trade | Brushless motor & Electronic Brake |

Key Things to Consider Before Buying
- Disc Size: A 115mm disc size handles standard metal cutting and grinding tasks easily. If you need deeper cut capacity for thick paving slabs, consider upgrading to a 125mm or 230mm model.
- Power Supply: Cordless grinders offer unmatched portability, but if you already own tools on a specific platform (like Einhell’s Power X-Change system), sticking to that brand will save you money on batteries.
- Safety First: If you are new to power tools, make sure to check out our step-by-step guide on how to use an angle grinder safely or read our beginner guide on angle grinder discs explained to ensure you buy the right accessories for metal or masonry work.
Note: Prices and specifications can change over time. Always check the seller’s current specifications and battery compatibility (Body Only vs. Full Kit) before purchasing.

| No-Load Speed: | 9,000 RPM |
| Weight: | 1.75 kg (Bare Unit) |
| Key Safety Features: | Electronic Brake & E-Clutch Anti-Kickback |
The DeWalt DCG405N is one of the most popular cordless angle grinders in the UK. Powered by an efficient 18V brushless motor, it delivers performance close to corded equivalents without the hassle of trailing cables.
Key Features & Performance
Because it runs on DeWalt’s standard 18V XR platform, it’s an ideal addition if you already own DeWalt cordless batteries. Its standout feature is its built-in safety pack: an electronic brake that stops the disc in under 2 seconds, and an E-Clutch system that automatically shuts down the motor if the wheel pinches or stalls.

Pros & Cons
- Pros:
- Brushless motor provides excellent runtime and tool life.
- Fast-acting electronic brake for enhanced user safety.
- Rubber over-mould body makes it comfortable for extended work.
- Seamless integration with DeWalt 18V XR batteries.
- Cons:
- Sold as a bare unit (battery and charger bought separately).
- Adding a heavy 5.0Ah battery increases overall working weight.

If you prefer continuous mains power over managing batteries, the Makita GA4530R is one of the best budget-friendly, compact corded grinders on the UK market.
Key Features & Performance
Driven by a reliable 720W motor, this unit features a slim barrel grip (179mm circumference) that makes it exceptionally easy to control during one-handed sanding or precise cutting tasks. At just 1.8 kg, it is significantly lighter than most cordless alternatives fitted with large batteries.
Crucially, the “R” suffix in GA4530R indicates the inclusion of Makita’s anti-restart safety switch, which prevents the tool from kicking back into life unexpectedly if power is cut and restored while plugged in.
Pros & Cons

Key Features & Performance
The standout feature on this model is its 5-stage variable speed dial. Lower RPM settings allow for precise material removal on stainless steel or delicate rust scraping without overheating workpieces, while high RPM settings handle fast slicing.
It also includes Milwaukee’s top-tier safety suite: a deadman paddle switch, RAPIDSTOP™ braking that halts the disc in under two seconds, and a FIXTEC system for fast, tool-free disc changes.
Pros & Cons
- Pros:
- Variable speed dial provides superior control on sensitive materials.
- Rapid braking and anti-kickback features make it exceptionally safe.
- Tool-free disc changes save time in the workshop.

How to Choose an Angle Grinder: Buyer’s Guide
Choosing the right angle grinder comes down to three main factors: power source, disc size, and safety features.
1. Corded vs. Cordless: Which Is Right for You?
| Feature | Corded (240V / 110V) | Cordless (18V Battery) |
| Best For | Garage/workshop DIY & long continuous jobs | Outdoor jobs, gardens, and jobsite mobility |
| Pros | Unlimited runtime, lighter (no battery), lower price | Complete mobility, no tripping hazards |
| Cons | Trailing cables, restricted by socket location | Battery adds weight, limited runtime, higher setup cost |
💡 Battery Platform Tip: If you already own 18V batteries from brands like DeWalt XR, Makita LXT, or Milwaukee M18, buying a bare-tool cordless grinder is highly cost-effective. If you don’t, factor in £60–£120 extra for a battery and charger.
UK Site Voltage Note: If buying a corded grinder for UK trade sites, remember that commercial building sites mandate 110V tools (fitted with yellow CTE plugs). DIY home users should stick to standard 240V UK 3-pin plugs.
2. Disc Size Explained: 115mm vs. 125mm vs. 230mm
The disc size dictates the maximum depth of cut you can achieve:
- 115mm (4.5″) – General DIY & Beginners: Smallest, lightest, and easiest to control. Perfect for cutting bolts, rust removal, and light metal fabrication.
- 125mm (5″) – The Versatile Upgrade: Offers ~35mm cutting depth. Highly recommended if you plan on tackling thicker steel tubing or patio cuts.
- 230mm (9″) – Heavy-Duty & Trade Masonry: Deep cutting for concrete beams and thick paving slabs. Unsuitable for basic DIY due to high kickback risk and heavy tool weight.

3. Essential Safety Features to Look For
Angle grinders operate at up to 11,000 RPM. When shopping, prioritize tools with these modern safety functions:
- Anti-Kickback Electronic Clutch: Instantly cuts power if a disc pinches or stalls, preventing the tool from jumping out of your hands.
- Electronic Brake / RAPIDSTOP™: Stops the spinning disc in under 2 seconds after releasing the trigger.
- Restart Protection (NVR): Prevents corded grinders from restarting automatically after a power cut if the power switch was left “ON”.
- Tool-Free Guard Adjustment: Allows you to reposition the safety guard on the fly without searching for a screwdriver.
- Anti-vibration: Look for models featuring rubberised or spring-loaded side handles. These significantly reduce vibration transmission to your hands and wrists, allowing for safer, and more comfortable use for extended grinding tasks.
🔗 Safety is paramount. Before using your grinder, read our step-by-step guide on how to use an angle grinder safely.
Cutting vs. Grinding Guards:
- Grinding Guards: Open-bottomed to allow material removal at an angle.
- Cutting Guards: Feature a clip-on attachment or full enclosure around the wheel edge to contain flying debris if a thin cutting disc shatters. Always ensure you use the correct guard clip when switching from grinding to slicing metal!
4. UK Price Expectations
- Under £50: Entry-level corded 115mm grinders (ideal for light, infrequent DIY).
- £50 – £100: Mid-range corded tools and entry-level 18V bare-unit cordless grinders.
- £100 – £200: Brushless bare-unit cordless grinders with electronic safety brakes and variable speed control.
- £200+: Premium trade-spec cordless kits including high-capacity batteries and heavy-duty cases.
Essential Angle Grinder Accessories
Using the right accessory for the job is critical for safety and performance. Never use an accessory outside its intended design or manufacturer RPM rating.
1. Metal Cutting Discs
- Best For: Cutting bolts, threaded rod, metal pipe, angle iron, and box section.
- Key Rule: Never use a cutting disc for side grinding. Applying lateral pressure to a thin cutting disc can cause it to shatter.
2. Grinding Discs
- Best For: Smoothing welds, removing heavy burrs, shaping metal edges, and rapid material removal.
- Key Rule: These are thicker than cutting discs and built to handle lateral load for surface shaping.
3. Flap Discs (Sanding & Finishing)
- Best For: Blending welds, removing rust, stripping old paint, and surface finishing.
- Grit Guide: Use 40-grit for fast material removal, 60-grit for general shaping, and 80-grit+ for smooth finishing.
4. Diamond Cutting Discs
- Best For: Cutting hard mineral materials including paving slabs, concrete, bricks, tiles, and stone.
- Tip: Always follow wet-cutting recommendations where required and wear appropriate respiratory protection against silica dust.
5. Wire Wheels & Wire Cups
- Best For: Stripping loose rust, scale, old paint, and cleaning weld joints before painting.
- Safety Warning: Wire bristles can fly off at high speed—always wear eye protection and a face shield.
6. Polishing Pads & Backing Plates
- Best For: Buffing stainless steel and specialized metal restoration.
- Note: Standard high-speed angle grinders can burn vehicle paintwork due to excessive heat; use a dedicated variable-speed polisher for automotive work.
7. Multi-Material Discs & Wood Safety
- Specialist Discs: Some multi-material blades can cut approved mixed materials if explicitly rated by the manufacturer.
- ⚠️ Crucial Warning: Never use a standard metal cutting disc on wood. Wood can bind and cause violent kickback. For general woodwork, use a circular saw or jigsaw instead. (Read our guide on can you cut wood with an angle grinder?).
8. Safety Accessories (Mandatory PPE)
- Essential Kit: Safety glasses, a full face shield, ear defenders, a dust mask (for masonry/metal dust), and sturdy steel-toe footwear.
Frequently Asked Questions (FAQ)
1. What size angle grinder is best for home DIY?
For general home maintenance, a 115mm (or 125mm) grinder is ideal because it is lightweight, easy to control, and compatible with a huge range of accessories. (Read our 115mm vs 125mm comparison guide).
2. Are cordless angle grinders powerful enough?
Yes. Modern 18V brushless grinders match the power of traditional 700W–800W corded tools while offering total portability for outdoor work and remote jobs.
3. Can I put a 125mm disc on a 115mm grinder?
No. Never force a larger disc onto a grinder unless it is explicitly manufactured and rated for that size, and never remove or modify the safety guard. (Read our full breakdown on can you put a 125mm disc on a 115mm grinder?).
4. Why does my angle grinder keep cutting out?
This is usually triggered by thermal overload protection, low battery voltage under heavy load, or tripping a circuit breaker due to high startup draw. (Read our troubleshooting guide on why does my grinder keep cutting out?).
5. Why is my angle grinder sparking?
Minor sparking inside the motor brush housing is completely normal for brushed tools. However, excessive showers of sparks from the disc usually indicate incorrect pressure, a damaged accessory, or cutting inappropriate materials. (Read our guide on why is my angle grinder sparking?).
Final Thoughts & Where to Buy
Choosing the right angle grinder comes down to balancing your power preference (corded vs. cordless), disc size, and safety requirements. For most UK DIYers, an entry-level 115mm tool provides more than enough capability for metal fabrication, rust removal, and occasional cutting.
