A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. AC, or flint stones. The size reduction is accomplished by the impact of these balls on the material as they fall back after being lifted by the rotating chamber.

Often used for slotting and pocketing cuts in mold and die making, these end mills have a 90° profile and rounded corners, which reduce flute breakage and chipping. All are center cutting, allowing plunge cuts into a surface. End mills with two flutes provide better chip clearance for high volume, highspeed plunge, slotting, and roughing cuts.

An end mill's overall reach, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It's measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deeppocket milling applications.
