High Speed Cordless Angle Grinder

Industrial Velocity and Torque for Metalworking Professionals

The high speed cordless angle grinder is a cornerstone of any professional metalworking or construction kit, providing the raw power needed for rapid material removal, cutting, and surface finishing. Traditionally, cordless grinders struggled with high-demand tasks like grinding welds or cutting thick rebar, often overheating or draining batteries in minutes. Our 20V high-speed model shatters these limitations by utilizing an industrial-grade brushless motor optimized for high-velocity output. Delivering up to 10,000 RPM, this tool provides the peripheral speed necessary for abrasive wheels to cut efficiently and for grinding discs to remove metal with the same aggressiveness as a corded 1000W tool. For the professional tradesperson, this means no longer being tethered to a generator or wall outlet, even for heavy-duty grinding applications.

The technical excellence of this grinder lies in its electronic control system. The brushless motor is governed by a sophisticated controller that provides "constant speed under load." This prevents the tool from bogging down when pressure is applied, ensuring a consistent finish and maximum efficiency. Safety is equally paramount; the grinder features an electronic brake that stops the wheel in less than 2 seconds, and an "Active Feedback-sensing Technology" (AFT) that shuts the motor down instantly if the wheel is suddenly forced to stop, protecting the user from dangerous kickback. An anti-restart function prevents the tool from starting if a battery is inserted while the switch is in the "on" position, a vital safety requirement for commercial job sites.

Durability and ergonomics were the primary focus of the mechanical design. The grinder features a high-strength aluminum gear case for superior heat dissipation and internal durability. The air intake is protected by a removable mesh screen that prevents metal filings and dust from entering the motor housing—extending the service life of the tool in harsh workshop environments. The handle is slim and rubber-overmolded for a secure grip, and the 3-position side handle allows for maximum control in any orientation. The tool-less guard adjustment allows the operator to reposition the safety shield in seconds without needing a wrench, improving site efficiency and encouraging the constant use of safety equipment.
