The EIV5 series from Millstar is revitalizing conventional practices for machine shops. With its combination of radial grind, variable helix, variable pitch and radius preparation, the EIV5 is a versatile endmill engineered for diverse machining applications.
Reinforced cutting edge allows increased chip load without risk of edge failure.
Variable pitch accommodates large step-overs with no bottom vibration.
Variable helix eliminates side vibrations while achieving greater DOC.
Corner radius preparation allows longer machining times without radius failure.
Exceptional performance with high-temperature alloys like titanium at 300sfm 2xD with 20 percent step-over and a 0.6 percent chip load.

- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- endmill
endmill
Milling cutter held by its shank that cuts on its periphery and, if so configured, on its free end. Takes a variety of shapes (single- and double-end, roughing, ballnose and cup-end) and sizes (stub, medium, long and extra-long). Also comes with differing numbers of flutes.
- pitch
pitch
1. On a saw blade, the number of teeth per inch. 2. In threading, the number of threads per inch.
- step-over
step-over
Distance between the passes of the toolpath; the path spacing. The distance the tool will move horizontally when making the next pass. Too great of a step-over will cause difficulty machining because there will be too much pressure on the tool as it is trying to cut with too much of its surface area.
