Replacement 5x8x15mm Motor Carbon Brushes for Angle Grinders & Power Tools

Restore sluggish motors, eliminate excessive sparking, and bring sputtering power tools back to full operational power. Designed for standard compact angle grinders, rotary hammers, and power tool motors, these 5x8x15mm replacement motor carbon brushes deliver consistent electrical contact between stationary wiring and spinning commutators. Formulated with dense, fine-grain graphite-carbon composite, each brush provides excellent thermal stability and minimal surface friction, ensuring smooth commutating performance with reduced electrical arcing. High-purity flexible braided copper wire leads maintain low resistance and steady current transfer under heavy tool loads, while matched coil springs supply optimal forward tension against the armature to prevent contact chatter. Supplied as a convenient 10-piece workshop pack, this power tool motor carbon brush set keeps your essential grinders, polishers, and shop tools running at peak performance.

Key Features

• Smooth Commutator Contact: High-density graphite-carbon block minimizes electrical arcing, motor vibration, and commutator ring wear.

• Low-Resistance Braided Copper Leads: High-purity flexible copper shunts handle high motor current draw without overheating or work-hardening.

• Consistent Spring Tension: High-resilience coil springs maintain even forward contact pressure as the brush block wears over time.

• Standard 5x8x15mm Dimensions: Matches universal brush holders across standard angle grinders, circular saws, and rotary power tools.

• Cost-Effective Tool Maintenance: Simple swap restores full motor RPM and torque, saving you from premature motor failure or costly tool replacement.

• Convenient 10-Piece Workshop Pack: Provides multiple replacements to service several workshop tools or keep backup spares ready in your toolbox.
