We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.

Ball milling is a key step in the processing of tungsten carbide parts. It ensures a good distribution of the different powders and reduces the crystallite size in the nanometer range by "mechanical alloying". The study of the influence of the rotation speed and the milling medium on the sinterability of the WCCo composite is important.

In addition, there may be a very thin end mill coating to further enhance performance. More about end mill coatings below. As one would expect, it is the tungsten carbide and not the binder that does the serious cutting. Hence, a lot of the quality of the carbide is a function of how much tungsten carbide grains there are versus how much binder.

Prepare tungsten: Grind your tungsten to a point. When welding on aluminum, the tungsten will begin to form a ball. If the ball grows to the same diameter as your tungsten, repoint the tungsten. Grind in the long direction and make the point roughly two and a half times as long as the diameter. Use a 200 grit or finer grinding wheel.
