Product Description

Three Flute Ball Nose End Mill / High Efficient Aluminum Ball Nose Drill Bit


KTC Ball Nose End Mills for Aluminum




Ball end mills are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. Because of the shapes required in these products it’s common that multi axis machining centers are used for this work. They can also be used in a secondary way to form a radius at the juncture of perpendicular surfaces. A ball end mill will produce a radius one half the diameter of of the tool used. A square end mill with a radius ground on the corner can provide a small radius at the juncture if reduction of stress is the desired objective.




A380CR high gloss aluminum milling cutter series adopt domestic high-quality fine grain tungsten steel material, flexural strength: 4100mpa, grain size: 0.8 μm, not easy to break the edge. A new special aluminum milling cutter with color coating is introduced, which increases the wear resistance of the cutter. The unique groove design and the polishing treatment of the front cutting edge and groove are adopted to increase the cutting performance. It is especially suitable for efficient and high gloss machining of aluminum alloy (6 and 7 series aluminum) materials.
