Pump Jack Scaffolding Rapid Descent Drill Bit Adapter

[Keith William Knull]

This adapter bit locks onto the crank shaft of a pump jack lowering mechanism. Made from a 1/2" socket with the sides ground off. Most effectively used with a variable speed drill that has a low-speed high-torque setting. It doesn't save a lot of time but it definitely saves a lot of effort.
