- Material and durability: These carbon brushes are made from carbon and metal materials to deliver durable, long-lasting performance. They are designed to be wear-resistant and to withstand friction and use in power tools and motors. - Replacement part: Among the most commonly replaced parts in power tools, these carbon brushes are essential spare parts. Over time brushes wear and must be replaced to maintain optimal motor function, electrical braking, and motor performance. - Wide compatibility and applications: Widely used in various power tools and motors, including circular saws, miter saws, electric drills, electric hammer drills, dust extractors, motorcycles, fan motors, cutting saws, angle grinders, and more. Compatible with multiple models and brands. - Optimal size: The carbon brush measures approximately 16 mm x 5 mm x 6.5 mm (L x W x H). The spring length is about 25 mm, providing a secure and stable connection. - Use scenarios: 1) Replace worn brushes in circular saws or miter saws to restore motor power and reliable braking. 2) Install in electric drills or hammer drills to maintain smooth operation and performance. 3) Use in fan motors, dust collectors, or motorcycle starters to preserve motor function across various brands and models.
