Is it Possible to Convert a Small Angle Grinder into a Table Saw for Cutting Mild Steel Sheets?

Yes, it is technically possible to create a setup that uses an angle grinder as a cutting tool similar to a table saw for making straight cuts in sheets of mild steel. However, it requires careful planning, proper equipment selection, and stringent safety measures. Below, we discuss the key steps involved in creating such a setup.

1. Angle Grinder Selection

When choosing an angle grinder for this project, consider the following:

Size: Opt for a small angle grinder, typically measuring 4.5 to 5 inches in diameter. This size is manageable and can be mounted securely on a table setup. Power: Ensure the grinder has a power rating of at least 10 amps to handle cutting through metal effectively.

2. Mounting the Grinder

The grinder needs to be mounted securely and adjusted to control the depth of the cut. Consider the following:

Table Design: Construct a sturdy table with a flat surface. You will need to create a mounting bracket to hold the angle grinder securely in place. Height Adjustment: The grinder should be adjustable to allow for precise control over the depth of the cut.

3. Cutting Mechanism

For accurate and straight cuts, consider the following cutting components:

Cutting Disc: Use a metal cutting disc specifically designed for cutting steel. Ensure it is rated for the angle grinders RPM. Guide Rail: Implement a guide rail system to ensure straight cuts. This could be a straight edge clamped to the table or an adjustable fence.

4. Safety Precautions

Ensure you take all necessary safety measures to protect yourself and nearby personnel:

Protective Gear: Always wear safety goggles, gloves, and a dust mask while operating the grinder. Dust Collection: Consider using a dust collection system or a vacuum attachment to minimize metal shavings and dust. Stability: Ensure the table and grinder are stable to prevent movement during cutting.

5. Alternative Solutions

For more precise and efficient cutting, other dedicated tools might be a better choice:

Plasma Cutter: If precision is critical, especially when cutting thicker materials, a plasma cutter may be a better tool to use. Dedicated Metal Cutting Saw: There are dedicated metal cutting saws designed for this purpose which might be more efficient and safer than using an angle grinder.

While using an angle grinder in this manner can be effective, it requires careful planning and adherence to safety considerations. If you are not experienced with such setups, it may be beneficial to consult with someone who has expertise in metalworking or to consider purchasing a dedicated metal cutting saw.
