Makita Releases Two New 5'' Flathead Grinders For The XGT System

New Flathead Grinders feature a lower profile for more access in tight spaces

Makita U.S.A., Inc., manufacturer of high-quality professional tools, power equipment, and accessories, has released two new 40V max 5” Flathead Grinders (GAG15 with slide switch, and the GAG16 with a paddle switch, each sold separately) that deliver the power of a 13 AMP corded grinder and have a category-leading low profile design for work in tight spaces.

The GAG15 and GAG16 give users two powerful and portable grinders that feature a low-profile 39° flathead design that delivers up to 45% more access in tight spaces when compared to a conventional full-profile angle grinder. Both Grinders have a variable 5-speed control dial for RPM adjustments (3,000-9,000 RPM) to match the speed of the application.

"The two new Flathead Grinders have a low-profile design that allows users to get into tighter spaces, making it an ideal solution for commercial welders, pipe fitters, and metal workers,” said Nicole Tougas, senior product manager for commercial products, Makita U.S.A., Inc. “With 13-amp corded power, and variable speed adjustments, these new low-profile grinders offer users greater versatility and efficiency on the job site.”

  • 40V max XGT 5" Paddle Switch Flathead Grinder (GAG16)

Additional Features
Both the GAG15 and GAG16 feature Active Feedback-Sensing Technology (AFT), which turns the motor off if the rotation of the wheel is suddenly forced to stop. They also feature anti-restart protection that is engineered to prevent motor start-up when the battery is inserted with the switch locked on.

Convenience Features
The new Flathead Grinders feature a tool-less wheel guard designed for faster guard installations and adjustments. They also have a removable dust cover that helps protect the motor from dust and debris. The Side Handle Adapter (327405-2) is also included, which extends the grip length for increased user maneuverability.

XGT is engineered to deliver high power to take on high-demand applications, allowing users to completely transition to a cordless job site.
