WARNING: All cutting tools can shatter and break during use. Government regulations require that safety glasses be worn during use. We also recommend wearing a simple respiration mask.

As the degree of taper increases, you may have to use the large diameter provided to calculate the appropriate RPM, instead of tip size. This usually isn’t necessary until seven degrees. At that time, the tip size would be used to calculate the needed feed per tooth. Tapered end mill usage can be tricky if the proper settings are not adhered to. Please follow these endmill usage charts as closely as possible.

The following tables are starting parameters only. Every application is different and may require varying feeds and speeds from this chart.
