Great price for the amount and it's easily available. Easy to dispense. Not much instructions on exactly how much and where to apply it, but it's really just needed in the splines of the bit to help lubrication back and forth so it doesn't seize if it's never been lubricated and then gets brick or stone dust in it grinding it. Not really needed on the end that gets hammered, but a little ending up there doesn't hurt. From what I'd read elsewhere I was expecting it to be black/dark grey grease which contains moly (to be rubber safe) but it looks like normal lithium grease. I expect this is compatible with the rubber sleeve on the SDS chuck of my Bosch drill, as it is made by Bosch and I presume it is universal, not just for one model of drill. I've never used grease on my SDS shanks up to now, although light use of the drill for drilling and chiselling over the years, I thought I'd better start using it. First use on a 5.5mm bit for a few small holes in brick, appeared to help with lubrication of the drill chuck and feel of drilling, the hammering sound was just slightly less harsh metallic sounding which I think is a good sign. It will ast a while because you don't need much, just on the splines. Maybe less than half a pea spread across all the splines. I will probably add a small amount to each size of bit and chisel (I have a few) as I use them to keep them lubed but they don't need it every time.
