Carbon Brush Grinder Electric Hammer 5*8*22.8/23.8 MM

High Quality Carbon Brush Grinder Electric Hammer 5×8×22.8/23.8 MM Electric Tool Accessories

Key Information Analysis:

1. Product Attribute: High Quality Carbon Brush Set
   Made of high-density graphite and high-purity copper powder (copper content approximately 25%-35%) through high-pressure pressing, it has three core characteristics:
   • High durability: The dense material is impact-resistant, able to withstand the high-frequency vibration and instantaneous high-load working environment of tools like grinders and electric hammers, with a wear rate 25% lower than ordinary carbon brushes;
   • Stable conductivity: The uniform distribution of copper powder improves current conduction efficiency, reducing sparks caused by poor contact and lowering the risk of motor overheating;
   • Strong adaptability: The set includes 2 carbon brushes of the same specification, meeting the need for simultaneous replacement of both sides of the motor, ensuring uniform wear and maintaining the operational balance of the equipment.
2. Compatibility Range:
   Based on the 5×8×22.8/23.8mm specification, it is mainly compatible with brushed motors of the following electric tools:
   • Grinders: Small bench grinders, handheld grinders (power 500-1200W);
   • Electric hammers: Lightweight electric hammers, impact drills (suitable for home decoration or small engineering scenarios, power 800-1500W);
   • Other tools of similar specifications: such as small angle grinders, stone cutting machines, etc.
     The core of compatibility is that the size must strictly match the original carbon brush and brush holder. The length difference between 22.8mm and 23.8mm must correspond to the equipment model (with an error of ≤0.2mm) to avoid over-tight installation or insufficient contact pressure due to inconsistent lengths.
3. Size Specifications: 5×8×22.8/23.8 MM
   This size belongs to small and medium-sized carbon brushes. The 5mm thickness and 8mm width are suitable for the compact brush holder structures of grinders, electric hammers and other tools. The two length specifications correspond to the installation depths of equipment from different brands. The dimensional accuracy is controlled within ±0.1mm to ensure no looseness after installation and reduce abnormal noise and sparks during operation.
4. Functional Roles:
   • Serves as the "power conduction medium" for grinders and electric hammers, stably transmitting current to the motor rotor, ensuring continuous output of the tools during grinding and impact operations;
   • The set design (2 pieces) facilitates one-time replacement of carbon brushes on both sides of the motor, avoiding increased equipment vibration or power imbalance caused by excessive wear on one side.
5. Replacement Tips:
   The carbon brush set should be replaced in time when grinders or electric hammers show the following conditions:
   • The carbon brush is worn down to less than 1/3 of its original length (about 7.6-8mm);
   • Sparks at the carbon brush increase significantly during tool operation, or accompanied by "stuttering" impacts;
   • The output power of the equipment decreases, such as weakened impact force of electric hammers or reduced rotational speed of grinders.
