For general reference cement is usually shipped in sacks containing one cubic foot of material. A barrel usually holds 4 cubic feet. Cement will deteriorate with age and will quickly absorb moisture so it should be stored in a dry place. For best results the sand and gravel used should be carefully cleaned free of humus, clay, vegetal matter, etc.

End Mill Cut Varieties: Centre-cutting end mills are those that can be plunged straight down into the material. They can mill, and they can drill. (They have cutting edges on the end face and the sides) These are usually the 2 flutes or 3 flute endmills, and occasionally you can find some 4 flutes that are centre cutting as well.
