55degree Solid carbide end mill,4flute end mill cutter,8mm carbide end mill, square cutting end mill
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).
Betalent carbide stocks lots standard end mills in its warehouse for fast shipping, and accept customization order by order for not common used flat end mills, or special design end mills.

Remark:
1,Betalent carbide keeps stock for standard size listed, ready to ship in most situations.
2,Size beyond this list can be customised as per drawing or sample.
For milling workpiece of which hardness is below HRC 60 to 65 degree, carbide grade BT60 is applied as raw material(ground carbide rod), BT60 has below physical characters:
| Grade | Co% | Grain Size | Density (g/cm) | Hardness(HRA) | TRS N/mm2 | Application |
| BT60 | 9 | 0.2 | 14.35 | 94.1 | 5000 | For cutting tools machining quenched materials (HRC60-65), hardwood and high polishing cutters. Finish machining 316L stainless steel.
