![]() They produce a much finer finish than two and three flute tools. Four/Multiple Flute designs allow for faster feed rates, but due to the reduced flute space, chip removal may be a problem.They are used for pocketing and slotting ferrous and nonferrous materials. Three Flute designs have the same flute space as two flutes, but also have a larger cross-section for greater strength.They allow for more chip carrying capacity and are used primarily in slotting and pocketing nonferrous materials. Two Flute designs have the most amount of flute space.Single Flute designs are used for high-speed machining and high-volume material removal.End mills with less flutes on the cutting edge will have more chip space, while end mills with more flutes will be able to be used on harder cutting materials. ![]() A higher number of flutes increases the strength of the tool and reduces space or chip flow. They have ground cutting tips that strengthen the end of the tool and reduce edge chipping.įlutes feature grooves or valleys that are cut into the body of the tool. Corner rounding end mills are used for milling rounded edges.They remove heavy material while providing a smooth finish in a single pass. Roughing and finishing end mills are used in a variety of milling applications.Both types provide longer tool life than square end mills. Corner chamfer end mills have an angled cutting edge and are used where a specific radius size is not required. Corner radius end mills have a rounded cutting edge and are used where a specific radius size is required.The tooth design allows for little to no vibration, but leaves a rougher finish. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. ![]()
