FEATURES AND BENEFITS: Electric Brake stops the grinding or cut-off wheel in 2 seconds or less for maximum productivity "Active Feedback sensing Technology" turns the motor off if rotation speed suddenly slows or wheel is forced to stop The BL Brushless Motor eliminates carbon brushes, enabling it to run cooler and more efficiently for longer life Variable speed control dial allows manual RPM adjustment (3,000-8,500) to match the speed to the application Slide switch with lock-on for operator convenience Soft start suppresses start-up reaction for smooth start-ups and longer gear life The electronically-controlled Brushless Motor efficiently uses energy to match torque and RPM to the changing demands of the application 3-stage L.E.D. gauge indicates battery charge level Spiral bevel gears for smoother rotations and a more efficient transfer of energy Rubberised soft grip provides increased comfort on the job Compact and ergonomic design at only 382mm long SPECIFICATIONS: Voltage: 18v
