Replacement 0.2 x 0.31 x 0.47 in Motor Carbon Brushes for Angle Grinders & Power Tools

Revive sluggish motors, stop erratic cutouts, and eliminate intense sparking to bring your favorite workshop tools back to life. Designed for compact angle grinders, electric hammer drills, and circular saws, these replacement motor carbon brushes deliver seamless electrical conductivity between stationary wiring and high-speed spinning commutators. Formulated with high-density, fine-grain graphite-carbon composite, each brush provides excellent thermal endurance and minimal surface friction, ensuring smooth commutating performance with reduced contact arcing. High-purity flexible braided copper wire leads maintain low electrical resistance and steady current transfer under heavy tool loads, while matched coil compression springs deliver optimal forward pressure against the armature to eliminate contact bounce. Supplied as a convenient 2-piece set, this power tool motor graphite brush set restores full RPM, torque, and reliability to keep your projects on schedule.

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 down naturally.

• Precision Universal Fit: Sized to 0.2 x 0.31 x 0.47 in to fit standard brush holders across angle grinders, hammer drills, and rotary tools.

• Cost-Effective Tool Restoration: Simple DIY swap restores full motor RPM and torque, saving you from expensive tool repairs or replacements.

• Convenient 2-Piece Set: Provides a matched pair to complete a full motor brush service in minutes.
