SDS Plus drill drive shaft cover / lubricator

SDS Plus drive shafts need periodic lubrication in order to perform. According to Wikipedia, ["The drill bit is not held solidly in the chuck, but can slide back and forth like a piston. [...] The shank must be lubricated with grease to allow it to slide in the chuck."](https://en.wikipedia.org/wiki/Drill_bit_shank#SDS_shank)
