Bosch 36618-02 18-Volt 1/2-Inch Compact-Tough Litheon Drill ...
The 36618-02′s Durashield Housing is constructed with ABS/Nylon composite, which makes the housing flexible and impenetrable. Durashield housing, unibody construction, and a steel-reinforced collar help you withstand real-world conditions, like temperature extremes, rain, dirt, debris, and drops. Additionally, the 36618-02 boasts an exclusive steel-reinforced collar that protects the nose of the drill. This ensures that the gears never separate from the motor, and it keeps the drill functioning even after drops. It provides extra reinforcement in the event of drops on the chuck and prevents the chuck from bending or breaking off.
