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.
