Rescue Your Makita Grinder: The Ultimate Housing Replacement
Your Makita 18V LXT Brushless Angle Grinder is the workhorse of your tool arsenal. But when it takes a nasty fall off a workbench or gets crushed in the back of a work van, the plastic exterior takes the hit. While the incredibly tough brushless motor usually survives, a cracked or split housing renders the tool unsafe. Taping it up isn’t an option—grinders spin at 8,500 RPM, and you need 100% structural rigidity to control them safely. The FixPartHub Replacement Housing Shell allows you to rebuild your grinder for a fraction of the cost of buying a new bare tool.
Why You Must Replace a Cracked Grinder Shell
Angle grinders generate highly conductive metal dust and abrasive debris during operation. The factory housing is specifically designed with air intake vents that channel cooling air over the motor while keeping heavy debris out. A crack in the casing breaks this airflow seal, allowing metal dust to bypass the internal filters and land directly on the sensitive electronic control board, leading to an inevitable and expensive short circuit. Replacing the shell immediately saves your internal electronics from destruction.
Precision Molded for Brushless Guts
Transferring the “guts” of a Makita DGA series grinder requires a shell with flawless internal geometry. Our replacement housing features exact-match screw bosses, trigger switch channels, and motor mounts. The battery slide rail is molded tightly to ensure your 18V LXT battery clicks into place securely without any power-interrupting wobble.

👨🔧 FixPartHub Pro Repair Tip: Angle grinders pack wires very tightly around the base of the motor. Before you pull the trigger switch or controller board out of your broken Makita shell, snap a few clear photos with your phone. Ensuring the wires are routed in their exact factory channels is critical so they don’t get pinched when you screw the two halves of this new shell together!
