Hello Sean,

I had a core sample taken from a large angrite (NWA 4931) I took to MIT for
magnetism analysis a few years ago. They used a 1/2" diamond-tipped bit with
water coolant and drilled in about 3" to get to the center of the stone. We
clamped the stone onto a drill press and made a makeshift 'girdle' to
collect the cutting sludge. The same process could be used dry but depending
on the type and density of the meteorite, you may have limited success.

Best Regards,
Greg

Folks,

Does anyone have experience taking a core sample from a chondrite for
repository / classification. The purpose would be to preserve certain
exterior characteristics by taking ~25 grams in a core and keep the 5gm
crusted plug. As a side note, considering most cores I found online
were marble cutting using water or a coolant, I would also be interested
if the process could be done dry, even if the cutting bit is wasted in
process.

Sean
