Don’t Let a Cracked Shell Ruin Your 18V Drill
The Bosch GSR18V-50 (Drill/Driver) and GSB18V-50 (Hammer Drill) are legendary for their tough brushless motors and compact power. However, accidents happen on the job site. When a drill is dropped onto hard concrete, the heavy internal metal components survive, but the exterior plastic casing often cracks, splitting the handle or breaking the battery rail.
Operating a drill with a compromised housing is dangerous, as the battery can fall out and debris can short-circuit the trigger board. The FixPartHub Replacement Housing Shell is the ultimate, cost-effective aftermarket solution.
Why Precision Internal Molding Matters
Look closely at the internal structure of this replacement shell. Swapping the “guts” of a high-torque 18V drill requires absolute precision. Every single groove, screw boss, and bearing seat is molded to exact factory specifications. If a replacement shell is off by even a millimeter, the planetary gears will grind, and the motor will vibrate excessively. Our housing ensures that your internal components align flawlessly, restoring smooth and powerful operation.
Stop Taping Your Tools!
We see it all the time: tradesmen wrapping their cracked drills in electrical tape or duct tape. This is a fatal mistake for brushless tools. The housing is geometrically designed to channel cooling airflow over the motor stator. Taping over cracks restricts this airflow, causing the motor to overheat and die prematurely. By installing a fresh, structurally sound housing, you restore proper ventilation and extend the life of your tool by years.

👨🔧 FixPartHub Pro Repair Tip: Before you disassemble your broken drill, use your smartphone to take several clear, well-lit photos of the internal wire routing. The thick power wires must be tucked exactly into their designated channels in the new shell. If they are out of place, you risk pinching a wire when screwing the two halves together!

Yes. This premium aftermarket replacement housing (clamshell) is manufactured to the exact factory dimensions to perfectly fit the Bosch 18V Professional brushless series. It is specifically compatible with both the GSR18V-50 (Cordless Drill/Driver) and the GSB18V-50 (Cordless Hammer Drill) models, providing a seamless fit for your original brushless motor and electronic module.
While a shattered case from a high ladder drop is the most common reason, internal heat damage is the silent killer. Pushing a drill too hard can overheat the motor, which melts the internal plastic bearing mounts and gearcase supports. If your motor wobbles inside the drill, or if the two halves of your handle no longer clamp together tightly, this new aftermarket shell will restore your tool’s structural integrity.
Brushless drills have extremely tight wiring. Crucial Pro Tip: Take detailed photos of the internal wire routing before you remove the old motor and trigger assembly! You must also remember to transfer the small, easily forgotten original pieces into this new shell: the top 2-speed gear selector switch, the forward/reverse shuttle, and the metal nut for the belt clip. When closing the new shell, double-check that no delicate control board wires are pinched.
