How to Cut and Grind Aluminium
Aluminium is one of the most widely used metals in fabrication, engineering, automotive, marine and architectural industries. Its lightweight strength, corrosion resistance and versatility make it a favourite across countless applications — but cutting and grinding aluminium correctly presents very different challenges compared to working with steel or stainless.
Using the wrong tools can lead to clogged discs, poor finishes, excessive heat build-up and wasted time. In this guide, we’ll explain how to cut and grind aluminium properly, the common mistakes to avoid, and why Pferd abrasives are widely regarded as the best choice for aluminium cutting and grinding.
Why Aluminium Needs Special Cutting & Grinding Tools
Aluminium behaves very differently from ferrous metals:
- It is softer and more ductile, causing standard discs to clog quickly
- Aluminium dust tends to stick to abrasive grains
- Excessive heat can smear the metal instead of cutting it cleanly
- Poor abrasives lead to rough edges, burrs and tool glazing
This is why professional fabricators and welders always use abrasive tools specifically designed for aluminium and non-ferrous metals, rather than general-purpose cutting or grinding discs.
How to Cut Aluminium Properly
When cutting aluminium, the objective is to achieve:
✔ Clean, burr-free cuts
✔ Minimal heat build-up
✔ No disc loading or clogging
✔ Safe, controlled cutting
Best Practices for Cutting Aluminium
- Use thin, purpose-made aluminium cutting discs
- Avoid excessive pressure — let the disc do the work
- Maintain a steady cutting angle
- Allow airflow to cool the disc
- Always wear suitable PPE
Standard steel cutting discs clog very quickly on aluminium, making cuts slow and uneven. This is why professional users choose tools like the Pferd SG ALU aluminium cutting discs, which are specifically engineered for aluminium and other non-ferrous metals.

These discs use a special abrasive and bond formulation that prevents loading, allowing for fast, clean, clog-free cutting, even on soft aluminium alloys.
How to Grind Aluminium Correctly – Grinding aluminium requires a different approach to cutting. Grinding is used for:
- Weld preparation
- Deburring
- Chamfering
- Surface smoothing
- Finishing
The key challenge when grinding aluminium is preventing the disc from loading with material, which causes vibration, heat build-up and poor surface finishes.
Best Practices for Grinding Aluminium
- Use aluminium-specific grinding wheels
- Keep the disc moving to avoid overheating
- Avoid steel grinding wheels on aluminium
- Clean grinding surfaces regularly
- Use light, controlled pressure
For professional results, Pferd SG ALU aluminium grinding discs are purpose-built for this task.

Pferd is globally recognised for engineering premium abrasive tools for specific materials and applications. Their SG ALU range is not a modified steel disc — it is purpose-designed for aluminium and non-ferrous metals.
What Makes Pferd SG ALU Tools Superior?
✔ Special abrasive and bond technology prevents clogging
✔ Excellent cutting and grinding performance on soft aluminium
✔ Longer disc life and fewer disc changes
✔ Cleaner surfaces ready for welding or finishing
✔ Consistent quality and safety standards
Pferd invests heavily in research and development, ensuring that their aluminium abrasives outperform generic alternatives in both productivity and safety.

Common Mistakes When Cutting & Grinding Aluminium
Avoid these costly errors:
❌ Using steel discs on aluminium
❌ Applying excessive pressure
❌ Allowing discs to clog before replacing
❌ Ignoring dust management
❌ Skipping PPE
Aluminium dust is fine and potentially flammable, so good housekeeping and extraction are critical when working with non-ferrous metals.
Preparing Aluminium for Welding
One major advantage of using Pferd SG ALU abrasives is that they contain no fillers that contaminate the surface, meaning aluminium cut or ground with these tools is ready for welding immediately — with no need for additional cleaning or degreasing.
This makes them ideal for:
- TIG welding preparation
- MIG aluminium fabrication
- Marine and automotive repairs
- Structural aluminium work
