This is a complete set with the pneumatic rock crusher and the mortar.
7.75" x 2" with a .400" outside diameter end that mounts in hammer. This air hammer attachment is custom made for the modern day gold prospector or miner. Fits in the average hand held pneumatic air hammer. Pulverizes hard quartz easily. Stands up to abuse of crushing hard rock. Makes sampling ore a piece of cake. Will crush rock below a 60 mesh in seconds. Takes the work out of crushing rock before panning, processing, or chemical or fire assaying. Very heavy and rugged. Requires little effort for anyone to crush hard rock.
6" tall by 6" inside diameter (6.5" OSD), 1/4" thick steel pipe with 1/4" heavy duty welded bottom. Weld is on the outside of the mortar. Mortar is painted black on the exterior only to prevent rusting during handling (not painted on the inside, expect some surface rust, which will not affect rock crushing.)
USE PROPER EYE AND RESPRITORY PROTECTION WHEN USING THIS EQUIPMENT!

This Pneumatic rock crusher and mortar works very well ,Crushed the material as expected.Now just to find the ore with the gold in it.
I bought the rock crusher for my son for Christmas. He was very excited his new rock crusher was able to be used with his air tools as he is a mechanic. He loves it.
I purchased this for crushing Coral Rock into powder for making custom aquascapes. Crushing Coral is like a knife through butter for this thing! Couldn't be happier. Wish I'd have bought this before I tried all the other methods that cost almost the same
