Special roughing end mills with serrations to break up chips are among the best tool types for removing material. However, they do produce a poor finish when compared to standard end mills. A final finish pass with a standard or finishing end mill will improve the surface finish. If space allows it, use a helical motion when plunging into a pocket.

When a ball-nose tool is used, smooth finish requirements may call for coolant's use. Here, the coolant serves as a lubricant. The problem with a ball-nose tool is that the tip of the tool has no surface speed. When a typical ball-nose tool takes very light finishing cuts, material can become trapped in the "web" design in this low-speed region.

Excess materials need to be stored safely and effectively to be ready for use. The flip side of this, of course, is a delay in delivery. If you don't have the materials and components ready for use, this causes a bottleneck before manufacturing can even begin. But forecasting goes beyond this.
