Buying Guide
Choosing an Angle Grinder for Mower Blade Sharpening
Sharpening your mower blades with an angle grinder is a cost-effective way to maintain a clean cut. When selecting an angle grinder for this task, consider these key factors:
Power and Size
Look for an angle grinder with a motor rated between 4.5 and 5 inches with at least 6 amps of power. This will provide sufficient power to grind the blade quickly and effectively. A smaller size improves maneuverability.
Safety Features
Prioritize grinders with a guard to protect you from flying debris. A two-handed grip is also important for control. Consider models with a lock-on button for continuous operation.
Disc Type
Youll need a grinding disc designed for metal. Look for discs specifically labeled for sharpening. These discs are typically abrasive and durable.

Is using an angle grinder the best way to sharpen my mower blade?
An angle grinder is a convenient and effective method for sharpening mower blades. Its often faster than using a file and allows you to restore a sharp cutting edge quickly. However, it requires a steady hand and proper safety precautions.
What type of grinding wheel should I use with my angle grinder?
You should use a grinding wheel specifically designed for metal, preferably one made of aluminum oxide. A coarser grit, such as 24 or 36 grit, will remove material quickly for efficient sharpening. Always ensure the wheel is rated for the speed of your angle grinder.
How do I safely sharpen a mower blade with an angle grinder?
Always wear safety glasses, gloves, and a dust mask when using an angle grinder. Secure the blade in a vise and grind at a consistent angle along the cutting edge, following the original bevel. Avoid overheating the blade, which can damage the metal.
What angle should I sharpen my mower blade to?
Generally, aim for an angle between 25 and 35 degrees. This angle provides a sharp cutting edge while maintaining the blades strength. Using a blade angle guide can help you achieve consistent results across the entire edge.
How often should I sharpen my mower blade?
Sharpen your mower blade at least once per season, or more frequently if you mow a large lawn or encounter a lot of obstacles. Dull blades tear grass, making the lawn appear brown and susceptible to disease. Regular sharpening promotes a healthier lawn.
