63 degree solid carbide end mills, 4flute end mill cutter, end mill tool, flat end mill

    Flat end mill can remove large quantity of workpiece blank material quickly, can semip-finish or rough milling of horizontal plane, profile, groove. Because of the general application character, flat end mill is more popular then other type of end mill.

There are 2 flute(for key slot milling), 3 flute(for aluminum or copper milling), 4 flute(general milling), 6 flute(special application most in customize) flat end mills. 4 flute flat end mill is the most general flat end mills.

For milling workpiece of which hardness is below HRC 55 to 60 degree, carbide grade BT55 is applied as raw material(ground carbide rod), BT60 has below physical characters:

    Because of the very wide application of carbide flat end mill,different carbide grades are applied as the material to different work piece materials, accordingly, carbide end mills can be classified by work piece hardness, there are flat end mills for milling HRC45(+/-3degree), HRC50(+/-3degree),HRC55(+/-3degree),HRC60(+/-3degree). Different coatings are applied to fit difference hardness material milling. They are copper TiSiN coating for HRC45, black NaCo4 coating for HRC50, light copper nACXCo4 coating for HRC55, blue nACo4 coating for HRC60. And for specific materials milling, there are specific design, specific coating combines specific carbide grades. For example, there are carbide flat end mills specially for aluminum and copper(BT50 carbide grade,no coating, AD coating or DLC coating), there are carbide flat end mills for stainless steels(BT50 or BT55 carbide grade, grey black TiAlSiN coating).
