New Metabo HPT 4-1/2” and 5” grinders

Metabo HPT launched two New 12Amp AC Brushless Grinders to its lineup; a 4-1/2” Paddle Switch Disc Grinder with Lock-Off Switch (model G12BYEQ) and a 5” Paddle Switch Disc Grinder with Lock-Off Switch (model G13BYEQ).

Metabo HPT G12BYEQMetabo HPT AC Brushless products permit the use of extra-long extension cords with reduced power loss, eliminating maintenance of armatures or carbon brushes, and delivering superior performance when powered by a generator due to internal inverter circuits for ultimate jobsite convenience. The AC Brushless motor results in the ultra-slim grip circumference of these grinders; reducing fatigue and improving control during continuous use applications.

Metabo HPT’s AC Brushless motors are more efficient; leading to longer run time, increased power, and extended durability with essentially no maintenance. Eliminating the need for carbon brushes means freedom from issues with the motor armature burning out and experiencing layer shorts or commutator wear in severe environments. Also, brush wear and resulting armature damage from lack of maintenance is the most common service issue. This is eliminated by the Brushless motor resulting in more uninterrupted run times.

Additionally, Metabo HPT’s Brushless tools integrate electronic controllers that compensate for reduced power loss due to voltage drop. The G12BYEQ & G13BYEQ AC Brushless Grinders are also designed for compatibility with a generator thanks to Metabo HPT’s compact and highly efficient inverter circuit. This circuit cleans up and modulates the electricity before it is used in the motor providing steady, stable operation and greatly reducing the risk of damage to the internal circuits. This is ideal for mobile contractors without a permanent power source on the jobsite.

These two new grinders offer 12 Amp high torque motors with 1,600 Max Watts Out to power through the toughest cutting and grinding applications. The no-load speed on both models is 10,000 RPMs. A soft-start function reduces the load felt by the user at start-up. The paddle switch cannot be activated unless the lock-off lever is pushed down for added safety. They accept 4-1/2” (G12BYEQ) and 5” (G13BYEQ) wheel accessories to tackle a multitude of applications, and easy-to-manipulate spindle locks located at the front of the grinders make it simple to change out the accessories (5/8 11-UNC spindle thread) as needed. The included side handles can be moved to either side of the grinders for added control and maneuverability. Both weighing just 4.6lbs, are lightweight for easy operation.

These grinders come with electric brakes, kick-back reduction, fine mesh dust filters and zero voltage restart protection. The electronic brakes stop the motors when the paddle is released. Kick-back reduction quickly shuts off the power in the event of a bound wheel to extend the life of the gears and protect the user from potential harm. The fine mesh dust filters prevent dust particles from entering the motor housing. Lastly, zero voltage restart protection prevents the grinder from restarting if power is temporarily cut during operation.
