Angle grinders are one of the most essential power tools for both DIYers and professionals. Their ability to cut, grind, polish, sharpen, and remove material makes them incredibly versatile. Whether you’re trimming metal pipe, cutting bolts, shaping paving slabs, cleaning up welds, or removing rust from old tools, an angle grinder can handle the job quickly and efficiently.
In the UK, angle grinders are available in a wide range of sizes, power levels, and configurations. The most common disc size is 115mm, which is ideal for general DIY use. Larger 125mm and 230mm grinders are typically used for heavier cutting tasks such as masonry, concrete, and thick steel.
Choosing the right grinder depends on your needs, budget, and whether you prefer corded or cordless tools. Cordless grinders have become extremely powerful thanks to modern brushless motors and high‑capacity lithium batteries, while corded models still offer unbeatable value and continuous power for long grinding sessions.

1. Dewalt DCG405N 18V Brushless Angle Grinder
Best Overall Angle Grinder UK
The Dewalt DCG405N is one of the most popular cordless grinders in the UK. Its brushless motor delivers excellent power while remaining efficient, giving you longer runtime and better durability.
Why the Dewalt DCG405N Stands Out
The DCG405N uses Dewalt’s brushless motor, which is more efficient, runs cooler, and lasts longer than older brushed designs. This means you get more cuts per battery charge and less wear on the tool over time. For cordless grinders, efficiency is everything — and Dewalt absolutely nails it here.

Essential Angle Grinder Accessories
1. Metal Cutting Discs (1mm Thin Discs)
Thin 1mm metal cutting discs are the most commonly used accessory for angle grinders. They’re ideal for fast, clean cuts through metal with minimal heat and resistance.
Best for:
- Cutting bolts, screws, and threaded rod
- Trimming metal pipe
- Cutting angle iron and box section
- Automotive repairs
Why they’re essential:
Thin discs cut faster, cleaner, and with less effort than thicker discs. They’re also inexpensive, so it’s worth keeping a pack in your workshop.
2. Grinding Discs (Thick Abrasive Discs)
Grinding discs are thicker and designed for removing material rather than cutting. They’re perfect for shaping metal or cleaning up rough edges.
Best for:
- Smoothing welds
- Removing burrs
- Shaping metal edges
- Heavy material removal
Tip:
Grinding discs remove material quickly — use with care to avoid taking off too much.
3. Flap Discs (Sanding/Finishing Discs)
Flap discs are one of the most versatile accessories you can buy. They combine grinding and sanding into one disc, giving you a smoother finish than a standard grinding wheel.
Best for:
- Smoothing welds
- Rust removal
- Paint removal
- Shaping and finishing metal
- Cleaning up rough cuts
Grit guide:
- 40 grit → heavy removal
- 60 grit → general shaping
- 80 grit → finishing
Flap discs are ideal for beginners because they’re more forgiving than grinding wheels.
4. Diamond Cutting Discs
Diamond discs are designed for cutting hard materials that abrasive discs struggle with.
Best for:
- Paving slabs
- Concrete
- Brick
- Tiles
- Stone
Why they’re worth it:
Diamond discs last far longer than abrasive discs and cut more cleanly through masonry.
5. Wire Wheels & Wire Cups
Wire wheels are excellent for cleaning metal surfaces without removing too much material.
Best for:
- Rust removal
- Paint stripping
- Cleaning welds
- Preparing metal for painting
Types:
- Wire wheel → flat surfaces
- Wire cup → larger areas
- Wire brush → tight spaces
Always wear eye protection — wire strands can break off at high speed.
6. Polishing Pads & Backing Plates
With the right backing plate, your angle grinder can be used for polishing metal and even automotive detailing (with caution).
Best for:
- Polishing stainless steel
- Buffing metal surfaces
- Automotive detailing (low speed only)
Note:
Use variable‑speed grinders for polishing whenever possible.
7. Multi‑Material Discs
These hybrid discs can cut through metal, plastic, wood, and more. They’re useful for quick jobs where you don’t want to keep swapping discs.
Best for:
- Quick cuts
- Mixed‑material demolition
- General DIY
Caution:
Avoid using standard metal discs on wood — always choose a disc rated for wood to prevent kickback.
8. Safety Accessories (Highly Recommended)
Angle grinders are powerful tools, so proper PPE is essential.
Must‑have safety gear:
- Safety glasses or face shield
- Cut‑resistant gloves
- Ear protection
- Dust mask or respirator
- Sturdy footwear
Optional but useful:
- Anti‑vibration gloves
- Apron or work jacket
Safety gear is inexpensive and dramatically reduces the risk of injury.
9. Tool‑Free Disc Change Systems
Some grinders support quick‑change systems like:
- Quick‑release nuts
- Keyless guards
- Push‑button spindle locks
These make disc changes faster and safer, especially if you switch between cutting and grinding frequently.
Summary: The Accessories You Should Always Have
For most UK DIYers, the essential starter kit includes:
- 1mm metal cutting discs
- 60–80 grit flap discs
- A diamond disc for masonry
- A wire wheel for rust removal
- A grinding disc for heavy shaping
With these five accessories, your grinder can handle almost any task around the home or workshop.
Frequently Asked Questions About Angle Grinders
1. What size angle grinder is best for home use?
For most UK homeowners, a 115mm angle grinder is the best choice. It’s lightweight, easy to control, and compatible with a huge range of cutting and grinding discs. A 115mm grinder can handle almost all DIY tasks, including cutting bolts, trimming metal pipe, removing rust, and sharpening tools.
If you need slightly deeper cuts, a 125mm grinder is a good step up. Larger 230mm grinders are only recommended for heavy‑duty masonry or construction work.
2. Are cordless angle grinders powerful enough?
Yes — modern 18V brushless cordless grinders are extremely capable. Models from Dewalt, Milwaukee, Makita, and Bosch can easily match the performance of mid‑range corded grinders.
Cordless grinders are ideal for:
- Outdoor work
- Garden projects
- Quick cutting tasks
- Jobs where dragging a cable is inconvenient
However, for long grinding sessions or heavy steel cutting, a corded grinder still offers the best value and unlimited runtime.
3. Can I cut wood with an angle grinder?
You can, but you must use a disc specifically designed for wood. Never use a metal cutting disc on wood — it can grab, bind, and cause dangerous kickback.
Safe options include:
- Carbide‑tipped wood discs
- Multi‑material discs rated for wood
- Chainsaw‑style discs (only for experienced users)
For most DIYers, a circular saw or reciprocating saw is safer for cutting wood.
4. What PPE should I wear when using an angle grinder?
Angle grinders are powerful tools, so proper safety gear is essential.
Minimum recommended PPE:
- Safety glasses or a full face shield
- Cut‑resistant gloves
- Ear protection
- Dust mask or respirator
- Sturdy footwear
Optional but useful:
- Anti‑vibration gloves
- Long sleeves or a work jacket
- Apron for sparks
Never use an angle grinder without eye protection — sparks and debris travel fast.
5. Why does my angle grinder kick back?
Kickback happens when the disc binds or catches on the material. Common causes include:
- Twisting the grinder during a cut
- Using the wrong disc for the material
- Cutting too aggressively
- Poor disc alignment
- Damaged or worn discs
To reduce kickback:
- Let the disc do the work
- Keep the grinder straight
- Use a disc rated for the material
- Maintain a firm grip
- Choose grinders with anti‑kickback features (Milwaukee, Dewalt, Bosch Pro)
6. How long do angle grinder discs last?
It depends on the type of disc and the material you’re cutting.
Typical lifespan:
- 1mm metal cutting discs: 1–5 cuts (thin discs wear quickly)
- Grinding discs: 10–30 minutes of continuous grinding
- Flap discs: 20–60 minutes depending on grit
- Diamond discs: Months or even years for DIY use
Diamond discs last the longest and are worth the investment for masonry.
7. Can I use a 125mm disc on a 115mm grinder?
No — discs must match the grinder’s rated size. A 125mm disc will not fit safely on a 115mm grinder and can be extremely dangerous.
Always use discs that match:
- The grinder’s disc size
- The grinder’s RPM rating
Never modify discs or guards.
8. Why does my grinder get hot?
Angle grinders naturally generate heat, but excessive heat can indicate:
- Overloading the motor
- Using too much pressure
- Poor ventilation
- Blocked dust filters
- Worn bearings
- Low‑quality discs
Cordless grinders may also heat up if the battery is struggling under load.
Let the tool rest if it becomes too hot to hold comfortably.
9. What’s the difference between cutting discs and grinding discs?
Cutting discs are thin (usually 1mm) and designed to slice through material. Grinding discs are thick and designed to remove material.
Never use a cutting disc for grinding — it can shatter under sideways pressure.
10. How do I know when to replace a disc?
Replace the disc if:
- It’s worn down significantly
- It’s chipped or cracked
- It vibrates excessively
- It cuts slowly
- It feels unbalanced
Damaged discs are dangerous — always inspect before use.
