- What this part does - Replacement carbon brushes designed to restore reliable motor function and electrical braking in compatible power tools. - Directly replaces worn brushes (examples: parts 999043, 999033) to eliminate intermittent operation and reduce motor arcing. - Key benefits — why you need these brushes - Restore motor performance: Replacing worn brushes reduces sparking, restores smooth, consistent motor speed, and helps the tool run as intended. - Recover electric brake function: New brushes can fully restore the motor’s electrical braking, improving safety and control during stops. - Durable construction: Made from a material engineered for durability and long life under normal operating conditions, so you replace brushes less often. - Important attributes - Function: Carbon brush for motor commutation and electrical brake recovery. - Compatibility: Suitable as a replacement for worn brushes identified by part numbers 999043 and 999033. Confirm fit for your specific tool model before purchase. - Performance: Designed to reduce intermittent operation and improve braking response when used as intended. - Maintenance: Brushes wear naturally from friction and use; routine inspection and timely replacement keep tools performing optimally. - Typical applications / use scenarios 1. Routine service for a bench grinder or handheld grinder showing reduced braking or uneven rotation — replace the brushes to restore braking and smooth operation. 2. Repair of a drill or driver that intermittently cuts out or sparks under load — installing new brushes can eliminate intermittent function and extend motor life. 3. Preventive maintenance on workshop tools that rely on electric braking (saws, sanders) to maintain safe stopping performance and precise control. - Installation and compatibility notes - Replace worn brushes promptly to avoid further motor wear. - Check your tool’s parts list or existing brush part number (e.g., 999043, 999033) to confirm compatibility. - If unsure, consult your tool manual or contact the tool manufacturer for fit confirmation. - Why choose these brushes - Purpose-built replacement for common worn brush issues: intermittent operation, loss of braking, and increased arcing. - Clear compatibility references (999043, 999033) and a construction focused on durability and reliable performance. For best results, inspect brushes regularly and replace both brushes at the same time to maintain balanced motor performance.
