Longlasting Material Carbon brushes constructed from durable materials to deliver longlasting performance and reliable operation. Commonly Replaced Part Carbon motor brushes are common wear items in power tools. Friction and use gradually wear them down, making replacement to maintain tool performance. Improves Motor Function Replacing worn brushes helps prevent intermittent motor operation, improves electrical braking, and restores motor power for consistent, dependable performance. Compatibility and Size Designed as replacement carbon brushes for power tools that use this standard component. Check your tool's model and brush holder specifications to ensure correct size and compatibility. Material and Size Details Material: carbon brush. Size varies by model; refer to your tool's brush holder specifications to ensure proper fit. Performance and Use Scenarios Applications: suitable for drills, drill drivers, grinders, routers, jigsaws, circular saws, and other tools that use carbon brushes. Scenario 1: A tool runs intermittently or loses power during use; replacement brushes can restore steady operation. Scenario 2: A tool's electrical braking feels weak or inconsistent; installing brushes can improve braking performance. Scenario 3: For tools subjected to heavy or extended use, replacing worn brushes helps maintain peak motor performance and reliability.
