The Makita angle grinder, renowned for its high quality, excels at cutting a variety of materials. However, when using a thin blade, the cutting wheel may stop unexpectedly. This situation can be caused by several factors, including blade selection, material to be cut, operation method, and more. This article will analyze these factors and offer some solutions and product recommendations to help users better address this problem.
Blade selection and material compatibility
Different materials require different blade thicknesses to achieve optimal cutting. Choosing the right cutting wheel thickness is crucial to ensure cutting efficiency and safety. Thin blades (usually around 0.04 inches) have the advantage of faster cutting speed, but are also more prone to warping or damage, especially when cutting hard or thick materials. On the other hand, thicker blades (over 0.1 inches) are more durable, but may reduce cutting speed.
In practice, if the material to be cut is hard, such as steel, the thin blade may not withstand the stress generated during cutting, causing the blade to stop or break. In this case, it is recommended to use thin cutting wheels such as the Makita A-93859 5-inch, designed for cutting steel, which combines the high efficiency of a thin blade with increased durability.
Cutting wheel diameter and power compatibility
The compatibility between the diameter of the cutting wheel and the power of the grinder is critical. If the grinder's power is not sufficient to drive a large cutting wheel, or if the wheel used is too thin, it may stall during high-intensity cutting. For example, when using a thin 4.5-inch cutting wheel on a low-power grinder to cut hard materials, the wheel may overheat or build up resistance, leading to it stalling.
To solve this problem, you can opt for a machine whose power is more suitable for the diameter of the cutting wheel. For example, the Makita GA7021 7-inch angle grinder, equipped with a 15-amp motor, is ideal for use with larger cutting wheels and performs excellently when cutting thick materials.
Method of operation and safety
The operation method also has a significant impact on the performance of the cutting wheel. Incorrect operation, such as applying too much pressure or an improper angle, will increase the risk of damage to the thin sheet, which could cause it to stop during cutting. When operating, it is important to maintain a proper angle between the cutting wheel and the material, and avoid applying too much pressure to prolong the life of the blade.
Safety is also important. When using cutting wheels, protective equipment should always be used and the angle grinder's rotation speed should be ensured to match the maximum safe speed of the cutting wheel. When using thin cutting wheels, it is especially important to avoid applying excessive pressure or uneven distribution of force to prevent blade breakage.
Recommended models and parameters
When choosing cutting wheels, it is essential to consider the thickness of the blade, the hardness of the material, the power of the grinder and the method of operation. Below are some recommendations for models and parameters:
1.Makita A-93859 5-Inch Thin Diamond Cutting Wheel
- Thickness : 0.045 inches
- Diameter : 5 inches
- Suitable materials : Stainless steel, carbon steel
2.Makita B-46165 7-inch coarse cutting wheel
- Thickness : 0.095 inches
- Diameter : 7 inches
- Suitable materials : High strength steel
3.Weiler 58059 4.5-Inch Thin Cut-Off Wheel
- Thickness : 0.04 inches
- Diameter : 4.5 inches
- Suitable materials : Thin-walled tubes, aluminum alloys
Conclusion
In summary, cutting wheel stopping when using a thin blade on a Makita grinder can be caused by improper blade selection, insufficient grinder power, or incorrect operating method. By selecting the appropriate blade thickness, ensuring compatibility between the equipment and the blade, and employing the correct operating method, users can significantly reduce the likelihood of this occurring and improve work efficiency. During use, it is recommended to opt for models such as Makita A-93859 and Weiler 58059 for better cutting results and longer blade durability.
