Efficient Brushless motor is electronically controlled to optimise battery energy use for up to 50% longer run time per charge A brushless electronic motor runs more efficiently than brushed types. This can help reduce the tool's energy consumption. Extreme Protection Technology (XPT™) is engineered for improved dust and water resistance for operation in harsh conditions

Variable speed control dial allows manual RPM adjustment (3,000-8,500) to match the speed to the application. The BL Brushless Motor eliminates carbon brushes, enabling it to run cooler and more efficiently for longer life The electronically-controlled Brushless Motor efficiently uses energy to match torque and RPM to the changing demands of the application

Automatic Torque Drive Technology: Automatically changes the cutting speed according to load condition for an optimum operation The electronically-controlled Brushless Motor efficiently uses energy to match torque and RPM to the changing demands of the application. Efficient Brushless motor is electronically controlled to optimise battery energy use for up to 50% longer run time per charge. The Makita DGA463 is a 115mm (4.5"), slide switch, variable speed angle grinder that's part of the ever expanding Makita 18V LXT lithium-ion battery cordless range.

Equipped with battery protection circuit: designed to protect the battery from damages due to overdischarge, high temperature or overload currentIt's powered by a Makita brushless motor for longer run time, increased power and speed, and longer tool life. For the most demanding applications, Makita’s exclusive "Automatic Torque Drive Technology" or ADT technology, automatically adjusts speed and torque during operation for optimal performance. The DGA463 is ideal for grinding and cutting a wide range of materials including tile, concrete, pipe, conduit, and more. Anti-restart protection engineered to prevent motor start up when battery is inserted with paddle switch in the on position Automatic Torque Drive Technology" adjusts speed and torque during operation for optimum performance. The Makita DGA454 is equipped with a highly enhanced Brushless DC motor. A built-in controller changes the cutting speed automatically according to load condition, enabling users to obtain high speed rotation on light duty application / high torque on heavy duty application. Battery fuel gauge LED's that also warn that anti-restart function and current limiter have been activated
