Can a 100MM Angle Grinder be used for cutting stainless steel?
As a supplier of 100MM angle grinders, I often get asked whether our product can be used for cutting stainless steel. The answer is yes, but with certain considerations and precautions.


Stainless steel is a popular material due to its corrosion - resistance, strength, and aesthetic appeal. It is used in a wide range of applications, from kitchen appliances to construction projects. When it comes to cutting stainless steel, a 100MM angle grinder can be a viable tool, but it's important to understand its capabilities and limitations.
How Does a 100MM Angle Grinder Work?
A 100MM angle grinder is a handheld power tool with a rotating abrasive disc. The disc spins at high speeds, usually between 6000 and 11000 revolutions per minute (RPM), depending on the model. When the disc comes into contact with the material, it grinds, cuts, or polishes it through the abrasive action of the particles on the disc's surface.
Suitability for Cutting Stainless Steel
Advantages
- Portability and Maneuverability: The 100MM angle grinder is relatively small and lightweight, making it easy to carry around and use in various locations. This is especially useful for on - site construction or maintenance work where large, stationary cutting machines may not be practical.
- Cost - effective: Compared to some specialized stainless - steel cutting equipment, a 100MM angle grinder is an affordable option. This makes it accessible for small businesses, DIY enthusiasts, and contractors on a budget.
- Versatility: Besides cutting stainless steel, the angle grinder can be used for other tasks such as grinding, polishing, and removing rust. With different types of discs, it can handle a variety of materials, not just stainless steel.
Disadvantages
- Heat Generation: Stainless steel has relatively poor thermal conductivity. When using an angle grinder to cut it, a significant amount of heat is generated at the cutting point. This can lead to several problems, such as discoloration of the stainless steel, hardening of the cut edges, and even damage to the abrasive disc.
- Limited Cutting Thickness: The 100MM angle grinder is generally suitable for cutting thinner stainless - steel sheets or bars. For very thick stainless - steel sections, the cutting process may be slow, and the grinder may struggle to make a clean cut.
Choosing the Right Disc
To cut stainless steel effectively with a 100MM angle grinder, selecting the appropriate cutting disc is crucial.
- Resin - Bonded Discs: These are the most commonly used discs for cutting stainless steel. They are made of abrasive grains bonded together with a resin. Resin - bonded discs offer a good balance between cutting speed and disc life.
- Diamond - Tipped Discs: For cutting harder grades of stainless steel or when a very smooth cut is required, diamond - tipped discs are a better option. However, they are more expensive than resin - bonded discs.
Precautions When Cutting Stainless Steel
- Safety Gear: Always wear appropriate safety gear, including safety glasses, gloves, a dust mask, and ear protection. The cutting process generates sparks, dust, and noise, which can pose risks to your eyes, hands, lungs, and ears.
- Workpiece Fixing: Secure the stainless - steel workpiece firmly before cutting. This ensures stability and helps prevent the workpiece from moving during the cutting process, which could lead to uneven cuts or accidents.
- Cooling: To reduce heat build - up, you can use a coolant or cutting fluid. Some operators also prefer to cut in short intervals and allow the workpiece and the disc to cool down between cuts.
Applications in Different Industries
- Construction: In the construction industry, 100MM angle grinders are used for cutting stainless - steel pipes, rails, and brackets. Their portability allows workers to make quick cuts on - site, adapting to the specific requirements of the project.
- Fabrication Workshops: Small - scale fabrication workshops often rely on 100MM angle grinders for cutting and shaping stainless - steel components. They are used to create custom - made parts for furniture, kitchen equipment, and decorative items.
