About this item

Product Description Restore smooth motor performance with these CB-440 carbon brushes for Makita power tools—precision-sized for stable contact, efficient commutation, and dependable replacement when brushes wear down. Ideal for drills/impact drivers using compatible Makita models. Key Features Stable electrical contact: Designed to move freely in the brush holder with recommended clearance ( 0.1–0.3mm ) to reduce rolling and improve commutation. Better switching performance: Helps maintain consistent power transfer for motors, generators, and similar rotating equipment. Wear-resistant build: Copper + carbon material supports long service life and durability in daily tool use. OEM-style replacement: Compatible replacement for MAKITA CB-440 carbon brush sets used in many 18V tools. Maintenance-friendly: Replace when worn; avoid mixing new and old brushes to help keep current distribution uniform. Correct orientation matters: Proper contact surface direction helps prevent low output due to insufficient contact area.
