3/8" DRIVE BREAKER BAR PARK TOOL SWB-15

The Park Tool SWB-15 is the 3/8" drive breaker bar designed to give extra leverage on seized or particularly stubborn bicycle fasteners. When a bolt refuses to budge, this 3/8" drive breaker bar lets you free it by applying force progressively and under control. It is the right tool for anyone who often works on high-mileage bikes, where fasteners tend to seize over time.

The body is made of forged steel and measures 368 mm (14.5"): a length that provides the leverage needed on the most stubborn fasteners. The 3/8" square drive head pivots 180°, so you can find the most comfortable angle around the component you are working on. The bar accepts any 3/8" drive tool: sockets, bits and bicycle-specific tools, including many Park Tool BBT bottom bracket tools. Thanks to the pivoting head, the bar can work in line with the bolt or at an angle, adapting to the space available around cranks, bottom bracket and hub.
