End Mills! (Your questions answered)

A slot drill is a two flute version of an end mill. They are specifically designed to plunge into material in the Z axis when milling a slot, e,g, for a keyway. Having only two flutes increases the space in the spiral of the tool which gives more room for chips to evacuate. This helps prevent the tool from clogging up and breaking when plunging.

Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
