Power tools 100mm Angle grinder speed

The speed of a power tool, such as a 100mm (4-inch) angle grinder, is typically measured in revolutions per minute (RPM). The appropriate speed for your angle grinder will depend on the type of material you're working with and the type of accessory (like grinding disc or cutting disc) you have attached.

As a general guideline:

1. Grinding Discs: For grinding applications, such as smoothing or shaping metal surfaces, the recommended speed is usually around 9,000 to 11,000 RPM. However, always check the manufacturer's specifications for the specific grinding disc you're using, as different discs can have different speed recommendations.

2. Cutting Discs: When using cutting discs to cut through materials like metal, including stainless steel, the recommended speed can vary. For most cutting discs, the typical speed range is around 10,000 to 13,000 RPM. Again, it's crucial to follow the manufacturer's recommendations for the specific cutting disc you're using.

Remember, operating your angle grinder at the appropriate speed is essential for both safety and achieving the desired results. Operating at speeds significantly higher than the manufacturer's recommendations can cause the disc to wear out faster, potentially leading to failure and posing a safety risk.

Always consult the angle grinder's manual and the documentation provided with your grinding or cutting discs for the exact speed recommendations. If you're unsure about the correct speed or how to use the tool properly, it's a good idea to seek guidance from someone experienced or consult the manufacturer for clarification.
