Heavy Duty 4-1/2" 10Amp grinder with dust ejection and kit box

10.0 Amp AC/DC 11,000 rpm motor designed for faster material removal and higher overload protection. Dust Ejection System™ provides durability by ejecting damaging dust and debris particles that enter the tool through the air intake vents. Low profile, jam-pot gear case provides precise gear alignment for a smoother, quieter transmission while allowing access to tight spaces. One-piece brush arm prevents brush hang-up due to dust ingestion. Quick-Change™ Wheel Release allows tool free wheel removal without need for a wrench. Keyless adjustable guard provides tool-free guard adjustments, increasing productivity. Auto-off brushes shut the tool down when the brushes need replacing to avoid tool damage.
