Rock Crusher and Mortar Combo Kit - Heavy Duty Gold Ore Crusher with Pestle - Perfect for Prospecting, Mining, and Geology Enthusiasts | Great for Crushing Rocks, Minerals, and Gemstones at Home or in the Field

This is a complete set with the pneumatic rock crusher and the mortar. Rock Crusher Details: 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 (specifically designed for use with the inexpensive Kobalt Model # SGY-AIR132 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. Mortar Details 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.)
