100 million pounds of cobalt and 150 million pounds of nicke 1 (1., .§.)3 is of enhanced importance because the cobalt and nickel content can be upgraded as a result of mill-ing operations. Although the ore contains an average of less than 0.04 pct Co plus Ni, 50 to 55 pct of this content is concentrated

So I put a NEW Shars 3/8" M42 cobalt 4-flute end mill into my knee mill and began to mill the surface. The surface to mill is about 1" square. As the End mill began "cutting" it began shreaking....right from the start. I did not cut even a 1/4" of the area when I decided to look at the end mill cutting end. It was already damaged.
I use cobalt drill bits a lot through. Have a lot of carbide ones as well, but cobalt drill bits seem to hold up much better then cobalt EM. Drilling in general is not as "intense" as milling. Also its easier to quickly sharpen drill bits - not so easy with EM. "Just for curiosity I did a look up on KBC. 3/8 4 Flute end mill. KBC branded.

Cobalt chrome molybdenum alloy is considered as one of the advanced materials which is widely gaining popularity in various engineering and medical applications. However, it is categorized as difficult to machine material due to its unique combination of properties which include high strength, toughness, wear resistance and low thermal conductivity.
Grinding to achieve greater liberation was necessary. The copper concentrate from the mill was about 50 to 58 pct minus 400 mesh, or an average particle size of 34 µm. After grinding 30 min in an 8-inch, laboratory steel-ball mill, the average particle size was 10 µm, and after a 45-min grind, the average particle size was 7.5 µm (fig- 3).
©2016 MachiningCloud, Inc. End Mill Materials | 7 End Mill Materials End mills are made out of either cobalt steel alloys (known as high speed steel, or HSS), or from tungsten carbide in a cobalt lattice (shortened to "carbide"). High Speed Steel (HSS): Provides good wear resistance and costs less than cobalt or carbide end mills.
