The Metabo 18V Cordless WVPB 18 LT BL 11-125 Quick 4-1/2” / 5” Variable Speed Paddle Switch Angle Grinder is German engineered and manufactured for safety, productivity, and extreme durability in a broad range of industrial grinding, cutting, beveling, and deburring applications. Metabo's 2nd generation BRUSHLESS Motor technology pushes true 1,100 Watt/11.0Ah corded power equivalent with a speed range of 2,800 – 10,000 RPM. In addition, it runs cooler and maximizes the energy transfer from the battery to the spindle, creating highest efficiency for extended run time, and maximum continuous power and productivity. The grinder's safety is enhanced by the patented Metabo S-Automatic safety slip clutch and electronic safety shut down, reducing the likelihood of kickback, immediately stopping the tool, and therefore helping the user maintain control if the accessory jams. The ergonomic non-locking paddle switch is designed to reduce fatigue and de-energize the motor immediately upon release, activating the electronic Metabo Brake System and stops the wheel in a matter of seconds. Grinding and cutting downtime is minimized with the M-Quick System for fastest tool-free wheel change at the touch of the large spindle lock button. The detachable dust filter and fully encapsulated motor ensure extreme durability by protecting the motor from dust and debris. Electronic features include vario-tacho-constamatic (VTC) speed stabilization for highest productivity, soft start for smooth start up and restart protection for unintentional restart after the power supply is interrupted. For additional user convenience the tool also features a 4-position locking rotatable battery pack, (1) tool-free burst proof adjustable guard (4-1/2” / 5"), dual-position reduced vibration side handle.
